The Hidden Risks of High-Frequency Noise

December 13, 2023

The Hidden Risks of High-Frequency Noise…

Noise, often underestimated, can pose significant risks to our well-being. Here is the second part of what you need to know:

🔹 Hearing Damage:

Exposure to harmful noise, especially in the workplace, can lead to permanent and disabling hearing loss. This damage can occur gradually over time or suddenly due to extremely loud noises. Such hearing loss can make it challenging to comprehend speech, engage in conversations, or even use the telephone. But that’s not all – noise can also trigger distressing conditions like tinnitus, disrupting our sleep patterns.

🔹 Safety Concerns:

Noise doesn’t just affect our hearing; it can create safety hazards at work. It interferes with communication, making warnings harder to hear, and reduces awareness of our surroundings. In essence, noise can compromise safety, putting people at risk of injury or


🌟 Health and Safety Regulations:

To mitigate these risks, companies must take action. Depending on the level of risk, they should reduce noise exposure and provide personal hearing protection to employees. The regulations also require companies to ensure that legal limits on noise exposure aren’t exceeded, maintain noise control equipment, provide education and training, and monitor workers’ hearing ability.

🌟 Identifying Noise Problems:

Companies need to ask themselves if they have a noise issue in the workplace. If any of the following conditions apply, action must be taken:

  • The noise is intrusive, akin to a busy road, vacuum cleaner, or a crowded restaurant, for most of the working day.High-Frequency Noise
  • Employees need to raise their voices to have a conversation.
  • Noisy-powered tools or machinery are used for extended periods.
  • The industry involves noisy tasks, like construction, woodworking, or foundries.

🌟 Safety Considerations:

Safety concerns related to noise arise when warning sounds are used to avoid danger, work practices rely on verbal communication, or when work is near mobile machinery or traffic.

🌟 Taking Action:

If you’ve identified noise-related risks at your workplace, it’s crucial to conduct an assessment and develop a Hearing Loss Prevention Plan to protect your employees’ well-being.

The RIGHT hearing protection for Machinists, Steelwork & Fabrication workers

February 24, 2023

dB Blockers™  for Machinists, Steelwork & Fabrication workers

“Workers in the shipping and steelwork industries are exposed to the highest levels of occupational pollution because they work close to heavy industrial blowers that produce sounds of up to 112 dBA or higher.” Industrial noise pollution is caused by plants and factories – it can have an impact on the people working within as well as those living around these industrial buildings.

Machinists, Fabricators and maintenance people need to hear their machinery sound a certain way to ensure that it is running properly, so they don’t often wear their earplugs correctly.

Without the proper protective equipment, steel workers become prone to hearing damage which hinders their ability to detect a machine’s problems before it breaks down, resulting in costly consequences. dB Blockers provide your workers with the complete protection and audible range needed efficiently doing their job.

Learn more about how dB Blockers fit perfectly and come in with a convenient handle (The Grip) for clean, easy insertion and removal. For welders, disposable earplugs are not only inadequate but also dangerous as they melt, and even burn when hot slag hits them.dB Blocker - The Grip

March is Hearing Loss Prevention Safety month.

March 23, 2020

Occupational hearing loss is the most common work-related injury in the United States.  Approximately 22 million U.S. workers exposed to hazardous noise levels at work, and an additional 9 million exposed to ototoxic chemicals.

An estimated $242 million is spent annually on worker’s compensation for hearing loss disability.

NIOSH recommends that all worker exposures to noise should be controlled below a level equivalent to 85 dBA for eight hours to minimize occupational noise induced hearing loss. NIOSH also recommends a 3 dBA exchange rate so that every increase by 3 dBA doubles the amount of the noise and halves the recommended amount of exposure time.

  • Four million workers go to work each day in damaging noise. Ten million people in the U.S. have a noise-related hearing loss. Twenty-two million workers are exposed to potentially damaging noise each year.
  • In 2008, approximately 2 million U.S. workers were exposed to noise levels at work that put them at risk of hearing loss.
  • In 2007, approximately 23,000 cases were reported of occupational hearing loss that was great enough to cause hearing impairment.
    Reported cases of hearing loss accounted for 14% of occupational illness in 2007.
  • In 2007, approximately 82% of the cases involving occupational hearing loss were reported among workers in the manufacturing sector.

Over the past few decades, much has been learned about the implementation of hearing loss prevention programs. The eight components of a successful hearing loss prevention program include:

1) noise exposure monitoring,

2) engineering and administrative controls,

3) audiometric evaluation,

4) use of hearing protection devices,

5) education and motivation

6) record keeping,

7) program evaluation, and

8) program audit.

Business in the Gig Economy

December 13, 2019

The gig economy is coming, and the manufacturing sector needs to prepare.

The gig economy is coming, and the manufacturing sector needs to prepare.

In this type of system, independent workers are paid by the gig, typically a specific project, and when that project is complete, the worker moves on. It’s a setup that is particularly appealing to millennials and is widespread in the IT and entertainment industries.

It is expected that within the next two years millennials will become the largest portion of the workforce demographic, and many of these workers will be employed as independent contractors. This is a dramatic change from the status quo, and it requires companies to form a strategy on managing what could be a constantly changing workforce.

Gig workers have a clear understanding of the work-life balance that they want, and they put as much emphasis on the life side of the equation as they do on the work side.

But jobs in the manufacturing sector are rooted in the long-standing tradition of advancing along an established career path. While the apprentice/journeyperson/master model has been replaced by the worker/team leader/manager model in many shops, the progression still takes time and commitment from both the employee and the employer.

Gig workers simply parachute into a company for a set amount of time and then leave once the task is done.

It’s a foreign concept for many manufacturers.

In his paper “Independent Workers: What Role for Public Policy?” American economist Alan Krueger wrote that currently the number of gig economy workers in the manufacturing sector is low. However, the longer the skilled-trades gap remains an issue for manufacturers, the more desperate they will get to find any type of worker to fill open jobs.

Because the manufacturing sector is having such trouble finding workers to fill full-time jobs, the gig economy could be a way to solve this problem, at least on a project-by-project basis.

Hearing protection

To survive in the gig economy, manufacturers must blaze their own trail and not try to copy other sectors.

No matter what type of worker is employed, a focus on productivity and quality still must be maintained.

In the gig economy, manufacturers should focus on a worker’s skill set and ability to mesh with a team, rather than the amount of time they will stay with the company.



The Not-So-Quiet Dangers of Hearing Loss

June 4, 2019

Take steps to prevent hearing damage in the workplace before it happens.

Some of the most prevalent workplace hazards aren’t seen—they’re heard. The National Institute for Occupational Safety and Health (NIOSH) reports that 22 million U.S. workers are exposed to damaging noise levels at work, and according to the Centers for Disease Control and Prevention (CDC), workplace-related hearing loss is the most commonly reported injury.

It’s not surprising, then, that hearing loss disability accounts for an estimated $242 million in workers’ compensation payments each year, according to the Department of Labor.

Approximately 48 million Americans have some degree of hearing loss, according to the Hearing Loss Association of America. The National Institutes of Health estimates that 15% of those aged 20 to 65 are living with some level of noise-induced hearing loss.

Noises over 85 decibels (dB) warrant the use of protection. For reference, normal talking is 60 dB, city traffic is 85 dB and a rock concert or a tractor is about 100-115 dB. Without proper protection, prolonged noise exposure in a factory setting can compound the hearing loss incurred from everyday noises.

Because hearing damage is cumulative and permanent, it is vital—and in many cases required—for businesses to protect their workers’ hearing, especially for those with a workforce exposed to loud machinery, power tools, and heavy equipment. In this article, we’ll examine the top industries affected by hearing loss and identify opportunities to minimize noise through hearing conservation programs.


hearing at work

From office environments to busy construction sites, workplace hearing loss is a reality for many industries. However, there are workers in certain roles who are at increased risk of hearing damage, and the needs of these employees should be more closely monitored and accommodated.

Hearing Loss in the Manufacturing Industry

For workers in the manufacturing industry, hearing loss is the most commonly recorded occupational injury. Between compressed air, which is an estimated 92 dB, and loud machinery like grinders, drills and milling machines, which typically hit dB levels 95 and above, it’s important for employers to take extra care to protect workers’ hearing.

Hearing Loss in the Construction, Carpentry and Mining Industries

Loud power tools also make workers in construction, carpentry and mining industries particularly susceptible to hearing loss. In fact, some tools, like a jackhammer, can reach up to 130 dB—more than 45 dB above the recommended limit. When exposed to these sounds for extended periods of time during a shift, the risk of hearing damage increases.

Likewise, miners are regularly exposed to sounds related to drilling into rock in a confined work environment, and as a result most miners have some form of hearing loss by the time they retire, according to the CDC.
Other industries most commonly affected by hearing loss include entertainment and nightlife, military, agriculture and farming.


Hearing is the body’s built-in alarm system and plays a vital role in protecting a person from physical harm. Hearing picks up on possible dangers that may not be visible yet, like the sound of an approaching truck or the clanging of a broken machine. However, when hearing is compromised, the built-in alarm system isn’t as effective and may not pick up on incoming dangers as quickly, putting workers at risk.

Workplace accidents are common among workers with hearing damage due to reduced situational awareness or the inability to hear a warning siren or signal.

The risks associated with hearing loss don’t stop there. Not only does hearing loss contribute to workplace-related issues, but it can also take a toll on an employee’s quality of life. Hearing loss is permanent, and as it worsens, it can make interpersonal communication difficult and frustrating, putting a strain on relationships. In addition, ringing in the ears associated with hearing loss can be disruptive to normal sleep patterns and concentration, which sometimes can increase the risk of depression, anxiety, and stress. All of these factors may contribute to underperformance or dissatisfaction at work.

hearing protection


When it comes to hearing loss, prevention is key. Almost all work-related hearing loss is cumulative and permanent, so it’s important for employers to take steps to prevent damage before it happens.

A great step in preventing work-related hearing damage is to implement a hearing conservation program. Not only do these programs protect workers from occupational hearing loss, but they can also play a role in increasing employees’ sense of well-being and reduce the incidence of stress-related disease. Stress decreases blood flow that helps hair cells within the ear work properly. Therefore, reducing workers’ stress can help maintain the overall health of the ear.

Hearing conservation is an OSHA mandate that requires companies to take action and institute occupational noise and hearing conservation programs for employees who work in areas where the probable exposure to noise equals or exceeds an eight-hour time-weighted average (TWA) sound level of 85 dB.

An effective hearing conservation program includes regular, ongoing sound monitoring, audiograms, employee training and protective equipment.

Regular, Ongoing Sound Monitoring

Sound level meters and dosimeters are two important elements of an effective hearing conservation program. Sound level meters measure sound intensity at a specific moment, while dosimeters measure a person’s average exposure to noise over a period of time. Employers can monitor and record sound levels throughout the workplace to help employees understand areas where the risk of hearing loss may be higher.


An effective hearing conservation program includes taking a baseline audiogram, which takes place 14 hours or more after the employee was last exposed to occupational noise. Following the baseline audiogram, annual audiograms should be performed to record any changes. These results should be analyzed and compared to previous tests to provide insights into how an employee’s hearing has changed. These changes are recorded as a Standard Threshold Shift (STS) if the loss is greater than a certain level.

An STS is a detectable change in hearing when compared to the baseline audiogram. If a shift is identified, an employer is required to inform the employee within 21 days and refer them to an audiologist for follow-up testing and possible treatment. This also is a good opportunity for both employers and employees to assess hearing protection methods and make any needed changes.

Employee Training

Training workers is another essential step to educating a workforce about the risks associated with hearing loss and the importance of prevention. At a minimum, employers should conduct an annual noise training with all employees, but regular reminders throughout the year are also recommended. For example, hanging educational posters and noise maps, which highlight decibel levels throughout the workplace, is a great way to remind employees throughout the year to take steps to mitigate hearing damage.

It can also be helpful to offer one-on-one educational sessions with individual employees who may be exposed to louder noises on a regular basis.

Protective Equipment

db BlockersIn addition to monitoring and training, employers must also provide workers with suitable equipment to protect hearing while at work. In fact, this is an OSHA requirement for workplaces where the noise levels meet or exceed 85 dB.

There are a wide variety of options when it comes to hearing protection devices and employers can often find several appropriate options that fit the needs of employees and the workplace. Examples include earplugs and earmuffs that come in a wide variety of different styles, like disposable, custom molded and reusable, to fit employers’ and employees’ preferences.

When it comes to safety, nothing is common sense

May 8, 2019

Woman’s business helps companies stay OSHA compliant

by Joe Gamm

There is no such thing as common sense.

osha-safetyWhat is obvious to one person may not be obvious to another, according to Bethany Graves (Watson), a consultant specializing in occupational safety based out of Jefferson City. Graves specializes in helping companies conform to Occupational Safety and Health Administration guidelines. 


Occupational Safety and Health Administration guidelines

Graves recently presented a program to the Jefferson City Area Chamber of Commerce, in which she explained the agency’s requirements, including employer and employee responsibilities, record keeping, training, and written programs.

She explained some of OSHA’s standards and guidelines.
The organization has a lot of guidelines. It must, Graves said, if it is to keep workers safe from harm. Despite OSHA’s work, more than 4,500 U.S. workers die in work-related incidents in private industry every year. For calendar year 2017, there were 4,674 worker fatalities. Of those, 971 (one in five) were in construction. The leading cause of private-sector worker deaths in construction (excluding highway collisions) were falls, then “struck by an object,” electrocution and “caught in or between.”

According to the agency website,, the top 10 most frequently cited standards violations in 2017 were lack of fall protection, failure to provide hazard communication, failure to meet scaffolding requirements, lack of adequate respiratory protection, lack of lockouts or other controls to prevent electrocution, improper use of ladders, violations of “powered industrial trucks” (or forklifts) regulations, lack of fall prevention training, failure to provide machine guards (to keep employees from moving parts), and eye or face protection.

On its website, the agency provides its guidelines for all industries in a 270-page document. Additional training information may be found elsewhere, according to the document.

The agency divides its safety guidelines into four categories, Graves said, general industry (which is generally made up of businesses that are static and do not fall into the other categories), agriculture, construction and maritime.

“Each industry has specific requirements,” said Graves, whose company, 365 Safety Services, does safety consulting for companies. “Some standards (within those industries) have even more requirements.” For example, within fall protection standards, there is what is called the “competent person,” who is responsible for the fall protection program and equipment and making sure everyone is using it properly.

The website also provides safety and training materials.

Graves helps businesses prepare for what happens if the agency does an inspection, tells them about how it works and explains businesses record-keeping requirements.

Safety Glasses

Basically, OSHA says employers must train their employees on everything — even how to put on safety glasses.

“If they’ve never done it before, you do,” she said. “The big thing is teaching employees the limitations of those glasses. When you’re grinding, you need to have a face shield on, too. So, it’s the limitations of the types of protective equipment.”

Hearing Protection

If someone has never hammered a nail into a board, and that’s their new job, they need to be trained how to do that, she said. In noisy work environments, where ear protection is necessary, an employer has to train the employees on how to install earplugs. in some cases, it is vital to hearing safety that proper wearing instructions of custom hearing prodBBlocker ducts also be applied. 

“You need to train them in where earplugs are required in the facility or on a construction job site, or on when the employee is using specific tools or equipment,” she said.

She suggested if employers aren’t certain if hearing protection is required that they go online and download a noise app for their phones. There is a variety of such apps on the App Store for prices ranging from $1-$20. If the app produces a reading over 90 decibels, the employer may need to do a noise level survey, which basically determines an average of the noise over eight hours.

Respiratory Protection

Respiratory protection is determined in a similar survey.

Proactive companies that have components of respiratory hazards have very particular requirements for respiratory tests. They require new employees to fill out an extensive medical questionnaire, receive a pulmonary function test and be examined by a physician.

“All industries might need it, including construction,” Graves said. “The smart companies have baseline hearing tests done upon hiring of a new employee. If they already have hearing loss — let’s say they like to four-wheel, shoot guns and listen to loud rock and roll — they may have already experienced some hearing loss. That’s on the record and not attributable to the company.”

Graves said she always recommends that companies, except for those with an office atmosphere, do hearing tests.

Inspections/Compliance and Consultations

OSHA has two sides — inspections/compliance and consultations. The consultation side will come into a facility for free and do a comprehensive assessment if requested. The organization will then write up a report and tell the company what it needs to improve on.

OSHA isn’t the scary organization many people make it out to be, Graves said.

“They’ve evolved a lot even since I’ve been involved in safety,” she said. “They used to focus on the compliance side. Now, they focus a lot on the company side of things. They want to provide consultations. They want you to train your employees. They provide online training. And they’ll come out and train as well.”

Inspection Process 

  1.  Companies should never know when OSHA is going to show up for an inspection. It is illegal for the agency to notify a company of an impending inspection. There are numerous reasons the agency may show up at a work site or company — if there were a fatality, if the agency received an employee complaint, if the business were the site of a serious injury where someone was overnight hospitalized, if there was an amputation or even because it’s part of the agency’s local emphasis. If OSHA sees a rise in certain kinds of work-related injuries, it may focus on a particular industry. “One year, they focused on funeral homes. Why would they focus on funeral homes?” Graves asked. “Formaldehyde. People were being exposed to formaldehyde.”
  2. Upon arrival at a site for an inspection, OSHA officials would begin by showing their credentials. They would then conduct an “opening conference” to tell the employer why they are there, such as one of the aforementioned causes.
  3. The third part of the visit is the inspection itself. “I’ve known companies that — on the inspection — (investigators) just said, ‘We want to see your OSHA logbook,’” Graves said. “They may just want to see your paperwork.” Or they may simply want to see one portion of a plant. On the other hand, inspectors can also observe from across the street for two days and then walk in, completely unannounced. “Maybe they just saw a job site that looked terrible — a guy working on a third-story roof with no fall protection,” Graves said. “That’s terrible. That’s what’s called ‘imminent danger.’ In that case, they probably wouldn’t sit across the street for two days. They would actually go up right then. “They don’t want anyone to die on the job.”
  4. The fourth step of an inspection is called the closing conference. It doesn’t happen at the time of the inspection. The inspector takes the data back to an area director, who determines which citation, if any, will be issued to a company and the fine associated with it.

About Bethany Graves – a consultant specializing in occupational safety 

Graves said that when she’s consulting with companies, she talks about safety not only within the workplace, but also at home. A person can just as easily receive a serious injury at home as they can at work, and that would prevent them from receiving a paycheck.

Young people coming into a construction company who have never used a hammer or saw before may just want a paycheck, Graves said. They don’t realize that what they do today is going to affect them for the rest of their lives, especially if they maim or seriously hurt themselves.

“I’m very passionate about safety. I always feel like no one should go to work and not come home,” she said. “What’s common sense to you is not common sense to me.

“One thing I hear from employers is, ‘It’s just common sense. He should know not to do that.’ I don’t believe anything is common sense.”

What is OSHA

OSHA is part of the United States Department of Labor. The administrator for OSHA is the Assistant Secretary of Labor for Occupational Safety and Health. OSHA’s administrator answers to the Secretary of Labor, who is a member of the cabinet of the President of the United States.

With the Occupational Safety and Health Act of 1970, Congress created the Occupational Safety and Health Administration (OSHA) to assure safe and healthful working conditions for working men and women by setting and enforcing standards and by providing training, outreach, education, and assistance.

OUCH! Its Cold out there so protect your hearing…

January 2, 2019

Hearing protection in cold weather.  Are you trying to keep your ears warm and also protected from noise exposure?


These tips from an audiologist can help.

Cold weather can present unique challenges for hearing health and safety. Workers can be exposed to potentially hazardous noises in industries across British Columbia, from avalanche control to oil and gas, drilling, road construction, and forestry, among others. When equipment and tasks are at odds with hearing protection, workers risk permanent hearing damage and loss.

“Hearing loss occurs when hair cells in the inner ear are permanently damaged due to repeated exposure to hazardous noise, regardless of the type of noise,” says Sasha Brown, the occupational audiologist in WorkSafeBC’s Risk Analysis Unit.

“Both the level or intensity of noise, and the duration or amount of time someone is exposed to noise interact to create the hazard. This is why it is essential for employers to have a hearing conservation program and provide appropriate hearing protection equipment to workers.”

Heli-ski guides are particularly at risk of developing hearing loss because their work involves being in close proximity to helicopters. When the mountains become frosted with snow, they help clients get into the backcountry to chase fresh powder and adventure.

Along with the excitement of this line of work, comes exposure to sound levels of around 100 decibels (dBA) from the helicopters they need to work in and around for long periods of time.

What is a safe level of noise?

Noise hazards are calculated by combining the dBA — the intensity of a sound measured in decibels on a sound-level meter — with the duration of time someone is exposed to the noise, Brown explains. Noise levels that exceed 85 dBA over an eight-hour time period are hazardous and could cause noise-induced hearing loss.

“Because decibels are a logarithmic scale, a three-decibel increase in noise doubles the amount of exposure.”

88 dBA is safe for 4 hours

91 dBA is safe for 2 hours

94 dBA is safe for 1 hour

97 dBA is safe for 30 minutes

102.4 dBA is safe for 8 minutes and 37 seconds

Safety talk

November / December 2018 | WorkSafe Magazine 17

“Heli-ski guides face additional risks because they are required to interact with their clients and listen for signs of avalanche danger,” says Brown. “This makes it difficult for guides to wear hearing protection throughout their entire work shifts. They, therefore, need hearing protection that can be easily placed and removed at will. “A further complication is that guides are required to wear ski helmets, and most noise-reducing earmuffs are not designed to fit around ski helmets. Guides might feel that they cannot wear both a helmet and hearing protection.”

heli skiing

The key, says Brown, is to understand the risks of hazardous noise exposure and protect yourself using the right hearing protection for your line of work. Heli-ski guides should use at least Class B-rated hearing protection because of the intensity and duration of noise to which they are exposed. In other industries, it may be necessary to test out different types of hearing protection to find the option that works best for you and your job.

Five tips you should know about protecting your hearing:

  1. Know your options for hearing protection. There is no one-size-fits-all when it comes to hearing protection. Investigate and test several different options with your employer to find the right fit for your hearing-protection and work requirements.
  2. Get an annual hearing test. This is an important way to gather information about whether your hearing protection is working effectively. Changes in your hearing ability could indicate a need to make some adjustments to your hearing protection, including its style, fit, and duration of use.
  3. Know the hazards of noise. Noise-induced hearing loss is both permanent and preventable. It has also been linked to cognitive decline and dementia, and can lead to social isolation. Get to know the risks associated with noise exposure, including the relationship between hearing loss and sound volume and duration of exposure. And always use sound protection when working around noises that exceed 85 dBA.
  4. Use well-fitted hearing protection. Hearing-protection needs vary by sector. If you choose to protect your hearing with earmuffs and also work in cold temperatures, you may need to remove your toque or beanie to ensure a proper earmuff seal — a thick toque can reduce hearing protection by up to 24 dBA. If you need to wear a helmet, make sure your earmuffs and helmet are compatible and do not compromise the earmuff seal. You may also opt for semi-insert canal caps or earplugs that fit underneath toques. These should not require a specific type of helmet.
  5. Frequently inspect your hearing protection. Work that involves a high degree of physicality and that takes place in an outdoor setting can speed up wear and tear on hearing protection. To prevent overexposure to noise from faulty or damaged equipment, inspect your hearing protection before each use.

Tips for protecting your hearing during the festivities.

December 14, 2018

Its that time of the year again. 

As a Hearing Conservation company we wanted to provide you with a few tips for protecting your hearing during the festivities:

  • Try to reduce as much background noise as possible. If you are having a conversation with a small group of people in a larger party, try to break off into a smaller section of the room that may not be as loud. Choose the calmest section of a restaurant or party to socialize in.
  • Sit in the center of the dinner table so you are close to people all around you. If you sit at the end of a long table, your chances of hearing the folks at the end of the table are minimal.
  • Try to keep good lighting to facilitate your ability to rely on facial cues to help fill in the blanks when you mishear something. We all lipread a bit. 
  • If the music is too loud at a party – as it often is – don’t hesitate to ask for the volume to reduced slightly or pull out your reliable dB Blockers to block some of that unwanted noise. 

You shouldn’t have to think about hearing over the holidays, however, if you find yourself constantly working hard to hear, or relying heavily on the tips above, it is time to have a hearing test. Contact us and we can help you protect your ears!
