Can Your Profession be Causing Hearing Loss?

June 24, 2016

You love your work but does your work love your ears?

If you are involved in these professions you may be at increased risk for NIHL (Noise Induced Hearing Loss).

  • Aviation – ground workers – factory workers – Within 25 meters of Jet take-off the noise level will reach 150 dB. That is loud enough to rupture eardrums. A Boeing 707 or DC-8 before landing is measured at 106 dB. A helicopter at 100 ft is 100 dB. Exposure to dB levels between 100 and 110 will lead to serious damage in as little as an 8 hours exposure
  • Construction Industry – jackhammers (100 – 120 dB), hand drill, belt sander or table saws (95-105 dB),air guns or pneumatic riveters at 125dB, compacting machines or sand blasting at (110 – 115 dB)
    Construction
  • Dentistry – Dental office equipment can also be a source for concern with ultrasonic cleaners at 90 dB, ultrasonic scalers and stone mixers at 85 dB.
  • Emergency / First Aid Responders / Firefighters – 110 – 140 dB of noise is produced by Ambulance or Fire truck sirens causing immediate pain to humans and can also rupture eardrums.
  • Farming – equipment operators can be exposed to noise from tractors (75-110 dB), Combine machines (80-105dB), Crop dusting aircraft or Orchard spray at 85-115 dB). Animals at feeding time in enclosed spaces such as a pig shed at 105dB.
  • Factory – In industry settings, the noise levels can average up to 90-125dB. A textile loom at 103 dB, riveting metal at 130dB, electric and pneumatic tools along with industrial heaters, coolers and venting machines all add to the noise exposure in industrial settings over the 90 dB levels.
  • Forestry Industry – Logging – Mill Workers – a Chain saw is approximately 120 dB – a painful level to endure. Noise from idling trucks and log moving and sorting equipment can expose workers to levels far above safety levels.
Forestry Mill
  • Gardeners & Landscapers – leaf blowers, snow blowers, power mowers (85 to 100 dB), hedge clippers, weed eaters all in very close contact can be a worrisome downside of the job.
  • Garbage Truck Driver – Sanitation workers can be exposed to 85 – 100 dB of noise from their truck – enough to cause tinnitus or possible damage in an 8 hour exposure.

  • Hunting or Target Shooting – A cap gun at 155 dB ,a 12 gauge shotgun blast at 160-165 dB or a .357 magnum revolver at 165 can all cause immediate and irreversible damage.
  • Military – An Aircraft carrier deck can reach 140 dB levels and a military jet aircraft take-off with afterburner can reach 130 dB both loud enough to cause immediate and permanent damage. A howitzer cannon at 175 dB or a rocket launch at 180dB can have devastating effects on hearing.
  • Music Industry performers and stage crew – singers. Rock concert speakers are measure at 110 – 140dB – again enough to cause human pain or even rupture eardrums. Stadium crowd noise can even reach 130 dB. Some professional singers have expressed their concern over hearing loss and some are being proactive in protecting their hearing
  • Motorsport Industry – Mechanics – pit crews – drivers. A single motorcycle at 100 dB, 114 dB for a driver inside a car during practice or noise levels in the pit of130 dB are all levels of concerns.
  • Road crews / Maintenance / Construction Sites – an auto horn measured at 1 meter can cause pain at 110 dB, an idling diesel truck 80 – 90 dB. Add that to road construction equipment and your exposure levels are dramatically increased.

What dB levels are cause for concern?

Hearing damage can occur at the following levels when exposed for these lengths of time.dB Metre

  • Higher than 85 dBa for 8 hours or more

 

 

 

 

 

 

 

 

Hearing protection over these far reaching professions and industries is a concern that affects directly or indirectly most people.

You may be directly affected or your hearing loss may have a negative impact on your personal and working life. Understanding the impact that noise can have on your hearing is the first step to taking action. The second is actually protecting your hearing under these conditions.

Monster Truck Jam is on! How much noise can you handle?

Monster Truck Jam is on! How much noise can you handle?

You grab your tickets, pack up the lunch and snacks, hustle the kids out the dMonster Truckoor and head out to the Monster Truck Jam, but wait… what’s missing? What about packing the hearing protection?

Entering an extremely loud noise environment can not only wreck your whole day (kids covering their ears, crying and wanting to escape the noise and begging to leave early) but also negatively impact anyone’s (yours included) hearing.

The WHO (World Health Organization) states on their website that “half o
f all cases of hearing loss are avoidable through primary prevention”. They go on to state that acquired causes that may lead to hearing loss at any age can be from “excessive noise, including occupational noise such as that from machinery and explosions, and recreational noise such as that from personal audio devices, concerts, nightclubs, bars and sporting events”.

So how much noise is too much noise and how long an exposure can be too much exposure?

How can we judge for ourselves when the noise level and length of exposure could be damaging to our hearing? Studies tell us that noise levels higher than 85dBA (in a measurement unit called the A-weighted decibel (dBA)), have been shown to be a cause for concern of noise induced hearing loss. Statistics from Health Canada – Noise induced hearing Loss site are very alarming. Can you relate to being in any of these noise situations?

Due to the noise around you: Means the sound levels are probably: Means you’re at significant risk of permanent hearing loss if exposed daily for:
someone standing a metre away has to shout to be understood higher than 85 dBA 8 hours or more
someone standing 30 cm away has to shout to be understood higher than 95 dBA 45 minutes or more
someone has to shout into your ear to be understood higher than 105 dBA 5 minutes or more

In as little as 5 minutes you can be at significant risk of permanent hearing loss!

Health Canada goes on to warn that: “The sounds around you may also pose a risk of gradual, noise-induced hearing loss if you experience either of these signs after a loud noise has stopped:”

  • a temporary hearing loss – sounds seem muffled, quieter or less clear
  • tinnitus – a ringing, buzzing, roaring or rushing sound in the ear, which has no source outside the ear”

So, maybe you won’t take the kids to the Monster Truck Jam but what other activities can expose you, your family and friends to sound levels above the 85dBA range? Some everyday activities such as:

  • mowing the lawn, using a weed eater, table saw, chain saw or other loud mechanical device
  • even driving a car on the highway with the windows open can be a source of concern.

Add up some of the noise levels you are exposed to that would be considered above the 85 dBA level and how long you are exposed to them. This will have a cumulative effect on your hearing over time.

How can you protect your hearing?

Part of the suggested preventative measures from the WHO include: “reducing exposure (both occupational and recreational) to loud sounds by raising awareness about the risks; developing and enforcing relevant legislation; and encouraging individuals to use personal protective devices such as earplugs and noise-cancelling earphones and headphones”.

Ear plugs, ear muffs and headsets can all offer some forms of mechanical protection. They are not all created with equal protection and some may protect but also exclude your ability to hear conversations or low level noise that you want or need to hear.

The dB Blocker™ Classic (Vented) from CPE is an example of how you can have your fun and protect against devastating hearing loss. Not only can you enjoy your noise filled event but with this model of hearing protection you can actually communicate better than without them! No more shouting in someone’s ear to be heard. The unique proprietary frequency-tuned filter enhances interpersonal communication. No excuses that your kids can’t hear you any more J.

So remember your hearing protection devices when you head into your noise filled fun activities.

Why Must Hearing Protective Devices (HPDs) Be Tested?

April 18, 2016

Why Must Hearing Protective Devices (HPDs) Be Tested? Is It Just for Labelling Purposes?

The Good, The Bad and The Unknown About Testing HPDs (Hearing Protective Devices)

Here’s your problem: You have a noisy workplace or workplace activity and you have a person who works in that noisy workplace or conducts the noisy workplace activity. You want to protect the person’s noise-exposure level so you turn to the Noise Reduction Rating (NRR) value from a Hearing Protective Device label to guide you in your choice of product. You do your calculations and trust the testing procedures to again guide you to make the best choice of HPD.

What should the concerned industrial hygienist, audiologist, or consumer do to protect the person’s noise-exposure level?

Let these 5 rules guide you:hearing protection devices

Rule 1. Be informed. The primary problem with HPDs is that they vary widely in effectiveness from individual to individual. Recognize that whatever rating value is on the label, it is a lower boundary, not a benchmark.

Rule 2. Recognize that HPDs, the head, and the ear are complex systems. The acoustics of HPDs aren’t accurately described by the principles of acoustics that were derived for large-scale systems such as walls, doors, windows, churches, and concert halls. HPDs and the head and ear to which they couple are a complex system. Change one element, or one part of one element of that system, and the entire system changes affecting the effectiveness of the HPD.

Rule 3. Employ fit testing if possible. The so-called gold standard for determining the effectiveness of an HPD is Real-Ear Attenuation at Threshold (REAT). The any type of fit-testing procedure is referred to as FAES – Field Attenuation Estimation System. The purpose of FAES is to insure that whatever HPD is used is effective for the individual’s noise exposure level. 

Rule 4. Select the HPD with the lowest possible NRR or, if available, the best SNR(SF84) for the noise exposure levels of concern.  The trend for the past 50 years has been to select the HPD with the highest NRR. This has resulted in many HPDs on the market that at face value are horribly overprotective.

Rule 5. Check the testing laboratory and the date of the testing. In general, try to ascertain if the testing laboratory is independent from the manufacturer. . Also, confirm that the laboratory regularly tests HPDs. For some products the data may be more than 30 years old from a laboratory that tested only one product. Also beware of excessively small standard deviations on the label; values less than 3 dB are suspicious.

What is the new CSA Z1007 Hearing Loss Prevention Program Management (HLPP) and what does it address?

April 15, 2016

CSA Z1007 Hearing Loss Prevention Program Management (HLPP)

In Canada the Canadian Standards Association (CSA) develops and maintains standards and codes that
impact the safety, environment, global economy and foster wider acceptance and adoption of new or innovative technologies. Volunteer experts from industry, governments, academia, regulators and consumers contribute to make standards work for people and business.

With workers in many occupational sectors being exposed to high levels of occupational noise it was critically important to identify these hazardous situations and implement preventative measures to help protect the hearing of workers.

CSA Z1007 – Hearing loss prevention program (HLPP) management is the first in a series of standards on occupational noise control to help address these potential concerns to worker health and safety. It covers all aspects of the creation and management of hearing loss prevention programs.

The standard helps guide businesses in establishing a management process for an effective hearing loss prevention program

SA Z1007 Hearing Loss Prevention Program Management (HLPP)

“The idea is to make them knowledgeable managers of hearing loss prevention programs,” explained Jeffrey Goldberg – Custom Protect Ear / chair of the technical committee, on May 1 at Partners in Prevention, an occupational health and safety conference.

 

 

“The standard tells the non-professional they need to do a noise survey,” he noted. “It doesn’t necessarily tell them how to do it; it tells them how to know they’re getting an effective one from a service provider that is going to do it for them.”

Some of the concerns addressed were the fact that there were different criteria for Action Levels, Protection Levels and Exchange Rates. The difference between Canada & the U.S.A. show in the chart below:

USA Canada
Federally Regulated and Inspected Provincially Regulated and Inspected
Regulations are Uniform Across the Country Different Criteria in 14 Jurisdictions Across the Country
Action Level – 85 dBA Action Level(s) – 80 (4), 82 (2), 84 (1), 85 (1), Not Specified (6)
Protection Level – 90 dBA Protection Level – 85 (11), 87, 90 dBA
Exchange Rate – 5 dB Exchange Rate – 3 dB (11), 5 dB (3)

To reduce the incidence of NIHL Z1007 needed to target both the knowledgeable and uninformed Manager and in order to be effective needed to be referenced in regulation by the Jurisdictions in Canada. Long-term exposure to noise can result in both hearing loss and stress-related illness. In addition, noise can interfere with critical communications and warning signals.

The Scope of the Standard outlines the Elements of an HLPP from Education and Training to Record Keeping. Elements include:

  • Detecting the Noise Hazard
  • Controlling Noise Exposure
  • Hearing Protective Devices
  • Audiometry
  • Hazard Communication and
  • Monitoring Program Performance

Some things left unresolved and next steps are to start the revisions for the next version and to address:

  1. Is Hearing Acuity a Fit for Duty criteria?
    • If it is, how do you deal with hearing impairment created by the work environment
    • If it isn’t, how do you keep people safe?
  2. What is the Protocol for Persons with Hearing Aids
    • There isn’t a single protocol that can address this issue
  3. Transient, Temporary, and Short Term Workers need to be covered – How do we do that?
    • Is this the employer’s responsibility?
    • Is this the regulators responsibility?

“Calling noise a nuisance is like calling smog an inconvenience. Noise must be considered a hazard to the health of people everywhere.”…. Former U.S. Surgeon General William Stuart

The Role of Standards in Making Occupational Hearing Loss Prevention Programs Effective

SUMMARY ON THE PRESENTATION

Workers in many occupational sectors – including manufacturing, mining, construction, transportation, and emergency services – often perform their jobs while exposed to high levels of occupational noise.

Long-term exposure to noise can result in both hearing loss and stress-related illness. Noise Induced Hearing Loss (NIHL) can be addressed with the implementation of a Hearing Loss Prevention Program (HLPP).

CSA Group has developed several standards that can help. This presentation will introduce the NEW Z1007 Hearing Loss Prevention Program Management – the first standard of its kind – which covers all aspects of creating and managing an organization’s HLPP, as well as review the important changes to the latest edition of Z94.2 Hearing Protection Devices. Your presenter, Jeffrey Goldberg is Chairman (formerly CEO) of Custom Protect Ear Inc. and the Director of Marketing and Public Relations for the National Hearing Conservation Association, in addition to serving as Chair of the Technical Subcommittee that wrote Z1007. Jeffrey will explain the content in Z1007, the changes to CSA Z94.2, and the cross-content between the two.

Sounds you can’t hear can still hurt your ears

March 10, 2016

All the shopping and socializing at this time of year can be enough to give you a headache, but could it actually be damaging your hearing?

On top of all the voices in busy stores and restaurants, many businesses pump up the music volume. So, when Global News received an email from a viewer concerned about noise levels, we decided to do an (admittedly unscientific) investigation.

Using a sound level meter and a smartphone app, we measured the decibel levels in various areas of an Edmonton mall with our viewer, Penny Jones

Sounds you can’t hear can still hurt your ears

What is it about Edmonton that makes them conscious of damaging our hearing. Several years ago, research done in Edmonton showed the noise levels at playoff hockey games exceeded what would be considered toxic in workplace.  Same thing happens with football games in Seattle.  Now, once again Edmonton has shone a light on this persistent problem.

too loud

Let me pose a question. What would be the response to 20% of the people of Edmonton, Chicago,  Paris, or London were all suffering from the same ailment; the same disease. I think the response would be significant.  

Over 20% of those working in noise suffer from some noise induced hearing loss (NHIL); an industrial disease. Contrary to popular belief, NIHL is not just the result of an  exposure to loud noise. It caused by the ears being tired from constant exposure to more sound than they can process in a 24 hour day.  Articles like this one, that alert the public to be aware of noise from all types of sources.  It increases our sensitivity to this problem. Imagine working all day in a loud workplace with proper hearing protection. Now add to that the noise from the mall or the game.  Your poor tired ears!

(The article talks about a smart phone sound measurement app. Very few of these apps are accurate enough to be used for more the curious interest). 

So please be aware of how often you are exposed to noise. Whenever you can, limit the level of exposure AND the time. When you get a break at work, move to quiet.  Let your ears “catch their breath”.  As my Jewish Grandma would say, “it couldn’t hurt”.   

Jeffrey Goldberg.

Reducing the Risk of Hearing Loss While Ensuring Compliance

November 13, 2015

Custom hearing protection might help you meet the hearing loss prevention trifecta: Fit, comfort and communication while wearing hearing protection.

At least 4 million workers go to work each day in damaging noise and 10 million people in the United States have a noise-related hearing loss. As many as 22 million workers are exposed to potentially damaging noise each year, according to the Centers for Disease Control and Prevention (CDC).

Occupational hearing loss is the most commonly recorded occupational illness in manufacturing accounting for one in nine recordable illnesses, according to NIOSH. Although a traumatic noise exposure may cause an immediate hearing loss in some cases, most occupational hearing losses occur so gradually that workers are unaware they are losing their hearing, adds the document. With continued exposure, the hearing loss spreads into those frequencies most needed to understand speech.

In many workplaces, disposable foam earplugs traditionally are used to block noise. However, their effectiveness depends not only on proper fit and the matching of the protector to their particular ear, but also on compliance. Do workers wear them consistently and correctly place them in their ears?

Most people wear disposable foam earplugs incorrectly, which limits their effectiveness. Each foam earplug is supposed to be rolled tightly, put deep in the ear canal then held in place with the index finger until it fully expands and the user can just see the outer edge. Instead, most people leave them hanging out of their ears.

Another challenge occurs when workers must talk in person or via two-way radio in high-noise work environments. To hear and communicate, they remove their earplugs, which exposes them to damaging noise for the duration of the conversation. Such cumulative exposure to harmful workplace noise is a leading cause of hearing loss.

People commonly remove earplugs to carry on a conversation. But if they remove them 20 percent of the time, they have reduced their effectiveness by half.

Essentially what is required to optimally protect workers is a hearing loss prevention trifecta: a device that delivers the proper fit, maximum comfort and the ability to communicate verbally or over radios without having to remove it.

To tackle the severe occupational hearing loss problem, it is helpful to consider the ideal solution, which requires allowing for all three factors.

The Hearing Protection Trifecta

First, an ideal hearing protection device would be customized to meet the needs of every employee or worker on the floor. That means fitting all ears regardless of differences in size, shape or depth. Like snowflakes, no two ears are the same – and they continue to grow throughout a person’s lifetime – so there is no such thing as one-size-fits-all when it comes to hearing protection. With better fit and comfort, workers probably would wear the devices correctly and compliantly.

Second, the hearing loss prevention device would prevent high-noise sounds from entering the ear at levels that could cause instant damage or damage over time. NIOSH recommends reducing worker noise exposure to 85 dB for eight hours, but this still can leave 12-15 percent with hearing loss over their work lives.

Third, the device would prevent high-noise exposure without limiting communication, and could be worn all day. In this way, the worker could wear it the entire workday, which would eliminate the hearing damage that occurs when typical earplugs are removed in high-decibel work settings to communicate.

Fortunately, a new generation of occupational hearing protection has been designed with the trifecta of custom fit, comfort and ability to communicate while wearing.

Custom Fit Might Be the Way to Go

If you make custom hearing protection available for everyone and ensure people know how to use it, studies have shown it can reduce occupational hearing loss to near zero in industry. Unlike one-size-fits-most disposable earplugs, some cost-effective hearing protectors are fitted to the individual worker so every worker receives the same high level of hearing protection.

Such custom hearing protection can be rendered quickly and cost-efficiently in an industrial setting. Companies that make personalized industrial hearing protectors custom mold hearing protection to each worker’s ear. The companies go to the plant to take impressions of each worker’s ear canal and outer ear in a process that usually takes about 10 minutes per worker.

The custom impression is sent to the lab for processing where the device, which is an exact replica of the wearer’s ear canal and outer ear, is manufactured.  This ensures the device seals the ear both in the canal and around the ear, preventing damaging noise from entering while eliminating ear pressure. Some companies are scanning the ear impression and moving into 3D printing of the casting for even closer fit.  Company representatives then return to the plant to train workers on how to ensure proper fit and fix any that do not fit perfectly.

A custom hearing protector fit can be a key part of preventing occupational hearing loss because everyone’s outer ear and ear canal is unique.  The closer the fit, the better the function and the less people take them out to relieve ear pressure or modify them as is common with disposable foam earplugs.

Comfort and Compliance

Since these unique custom hearing protection devices are made of a medical grade silicone, they are designed to be soft and flexible. The advantage of the softer devices is better comfort and function. They change shape slightly as the wearer’s ear canal changes shape when talking or chewing, thereby continuing to seal during those activities.

Greater comfort addresses a significant problem facing health and safety managers who oversee hearing loss prevention programs: getting people to wear hearing protection products and policing their use.

Communication While Wearing Hearing Protection

Since factory workers often need to communicate in person during their work shift, they typically remove disposable earplugs to talk. Some custom hearing protection includes a filter and vent to make speech more understandable by reducing attenuation at higher speech frequencies.

Talking by two-way radio is also common in manufacturing settings. But because a radio must be louder than factory noise for a worker to hear it, it usually is the loudest sound source in the work setting and must be protected against to avoid hearing loss.

To deal with this problem, manufacturers of certain custom hearing protection devices can connect incoming radio audio to the outside of the hearing protector so the device’s filter reduces dB volume and the worker does not have to remove the hearing protector to talk on a two-way radio. Because filters “squeeze” high and low frequencies to block potentially harmful sound waves, communication comes through but harmful noise does not.
