Happy Canada Day from CPE !

July 1, 2016

Happy Canada Day!

July 1st Celebrations for Canada Day is here. Are you prepared? Do you have your BBQ ready for the summer backyard celebrations? Is your cooler stocked? Your Canadian flags flying?

Are you also prepared to protect your hearing when the fireworks begin? A firecracker going off in close proximity can have a decibel level of 145 dB, loud enough to cause immediate damage to your hearing! What about a popping balloon at 125 dB or crowded stadium or concert noise at 130 – 140 dB where damage can appear in as little as 1-4 seconds with no hearing protection.

Fireworks

Do you have plans that include young children attending a fireworks display? Make sure you protect their hearing as well as your own or other adults in attendance so you can continue to enjoy July 1st celebrations for many years to come.

Canada bday

Bring out your dB Blocker™ hearing protection for your whole family and tell your friends as well. They will thank you to the stars and back… or where those starburst fireworks 😉

 

Happy Canada Day from all of us at CPE – Custom Protect Ear.

What is a decibel and how is it measured?

June 29, 2016

What is a Decibel?

The decibel (dB) is a unit used to express the energy in a sound wave.

How is a Decibel Measured?

The measurement of a decibel is a logarithmic scale measurement. Named in honour of Alexander Graham Bell and originally used to measure output along telegraph cables it expresses a ratio or comparison of two quantities. One decibel is one tenth of one bel and is the common reference name.

Measuring to Protect our Hearing.

Used for acoustic purposes or defining how loud a sound is to the human ear the dB expresses sound pressure level. This gives us an indication of what the human ear can tolerate or how sensitive our hearing is to certain levels of noise. Knowing the levels that the human ear can tolerate and how long it will take to cause damage allows us to take preventative measure to protect our hearing. Being able to measure the dB levels of equipment, vehicles, and sound producing objects gives us an advantage to know what we need to avoid or how long we are able to tolerate certain levels of noise.

Starting at the lowest level or the quietest thing that can be heard the decibel is expressed as 0 or 0dB. At levels over 85dB hearing loss or tinnitus can occur. At the pain level or very loud level the decibel is expressed as 120dB. Over 140dB can cause immediate and irreparable damage.

Noise level X exposure level

Being exposed to decibel levels below 80dB will rarely be a cause for hearing concerns. However, being exposed to higher level can definitely be concerning. The higher the level, the shorter the time exposure will be before noise induced damage will take effect. The National Institute for Occupational Safety and Health (NIOSH) suggests time frames for safety exposure.

  • At levels of 85dB hearing damage can occur after 8 hour exposure
  • At levels of 90dB hearing damage can occur after 2 hours of exposure
  • At levels of 94dB hearing damage can occur after 1 hours of exposure
  • At levels of 100dB hearing damage can occur within 15 min of exposure
  • Over 112 dB hearing damage can be immediate and permanent

To get an idea of what dB levels are for different noises and what effect they can have on your hearing see the chart below:

  • Normal Breathing 10 dBNIOSH Decibel readings

  • Normal conversation 50-65 dB

  • City traffic noise 80 dB

  • Lawn Mower 85-90 dB

  • Garbage Truck 100 dB

  • Jackhammer 110 dB

  • Stereo or headset 110 – 130 dB

  • Rock Concert 120-140 dB

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.
    Screen Shot 2016-06-20 at 1.07.35 PM
  • 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.

What is 3D printing?

June 2, 2016

What is 3D printing?

We’ve all heard about 3D and understand the concept of 3 dimensional (3D) viewing but how does that translate into 3D printing?

3D printing is a process of making three dimensional solid objects from a digital file (picture). The descriptive term for 3D printing is “Additive Manufacturing” which gives us a visual clue as to the process behind 3D printing. The object is actually created through a layering process utilizing specialized 3D scanners and 3D printers.

How does the 3D Printing Process work?

The first step is to create a virtual design or blueprint of the object you want to create. This can be created using a 3D modeling program in a CAD (Computer Aided Design) An existing object can be copied with the use of a 3D scanner. This technology is being used by many technology companies such as Microsoft and Google who have developing hardware to perform 3D scanning. Microsoft’s Kinect is an example of what the future may hold for smartphones and other hand-held devices having integrated 3D scanners. In the very near future this digitalization of real objects into 3D models will be performed as easily as taking a picture on your smart phone is now.

The 3D printing software “slices” the final model into hundreds or even thousands of layers several microns thick in preparation for printing

The second step to the process is sending the finished design to the 3D Printer where the received data is now recreated by bonding very thin layers of resin together into a finished object. There are several different methods and materials used in 3D printing depending upon the object needeDigital Printing d to be manufactured but the one similarity is the use of a layering process.[1]

Depending upon your desired finished product there are several options or types of 3D printing. Some involve heating and solidifying granular material by laser technology with each slice in the needed pattern. This is repeated over and over again with each patterned layer bonding to the previous layer as it cools. Other 3D printers will spool out or deposit material much like an automated glue gun while others use UV light to cure layers of resin.

How does Custom Protect Ear (CPE) utilize this 3D Technology to help your ears?

CPE is using this “cutting edge” technology (literally!) to compliment their existing high quality custom hearing protection.

The digital 3D printing technology used by CPE creates an accurate and precise Hearing Protection Device (HPD). CPE utilizes DLP (Digital Light Processing) technology (the most precise in the market) through the EnvisionTEC ULTRA® 2 printer.  The technology provides benefits both to the wearer and to the product development process:

  • Quality in consistency during HPD modeling means accuracy and precision
  • Quality Control during product implementation ensures proper fit for the wearer
  • New designs can now be updated and printed in real time, improving implementation of new design developments.

The DLP technology allows for the ability to add more product features in ways which were not always possible before. For example, CPE can place an employee number or serial number of any size anywhere on the HPD, unlike being limited to the outer surface with traditional technology.

The traditional method of producing ear moulds includes manual physical cutting and grinding of the ear impressions to shape them close to the shape of the finished product. Plaster moulds are then created based on these impressions, and silicone is placed into the prepared moulds.

The final quality performance check (ensuring the HPD is accurate and precise) is completed when the original impression and the new 3D model are overlayed on screen Following this, the moulds are printed in the digital 3D printer. The final HPD is obtained by pouring silicone material into the mould.

The 3D Approach

3D Printing digital moulds

CPE has been using this new 3D approach for almost 3.5 years integrating it with their already custom design method of producing ear moulds for dB Blockers, dB Com and dB Life products. The ability to create complex objects is revolutionizing the manufacturing industry and improving quality and consistency in products produced using this 3D technology.

JUST MORE PROOF THAT CPE IS COMMITTED TO THEIR CUSTOMERS WITH ONGOING RESEARCH AND TECHNOLOGY IN THEIR BEST PRACTICES.

Can allergies play a role in hearing loss?

May 27, 2016

Can allergies play a role in hearing loss?

You are suddenly concerned that you have ringing in the ears or sounds appear more distant. You are asking people to repeat themselves and turning up the volume on your TV because you just can’t hear as well. Could these be symptoms of hearing loss? Yes, absolutely! Should you be concerned? Yes, absolutely! Are these signs of permanent hearing loss? No – not necessarily – they could be signs of either seasonal or perennial allergies!

Allergies?

You may have temporary hearing loss due to symptoms of allergies affecting your inner ear.

In the U.S. it is estimated that one in five people either have allergy or asthma symptoms. The number of people with chronic allergy-like symptoms such as runny nose, congestion and cough but actually have non-allergic rhinitis instead is one out of three. 

Allergies rank 5th in leading chronic diseases in the U.S.  

Seasonal Allergies have their affect on people normally in spring, summer or early fall. Most often they are caused by sensitivity to pollens from either trees, grasses, weeds or airborne mold spores. allergy-grass-pollen

Perennial allergies affect people year round and usually are because of sensitivity to something a person is constantly being exposed to such as dust mites, mold spores or animal dander from cats, dogs or rodents.

Another cause of allergies could be a reaction to certain substances or clothing. Some people using hearing aids or hearing protection devices can actually react to the material the device is made from. Other concerns from HPD’s could be improperly fitted or improperly vented devices causing a build up of pressure or moisture in the ear. The dB Blockers™ HPD’s from CPE are fitted to each employee exactly – eliminating ear pressure. They are also composed of SkinSoft™ a hypoallergenic, non-flammable silicone blend of material.

How do allergy symptoms affect hearing loss? 

When you are exposed to an allergen your bodies natural defence system kicks in. Your immune system responds to allergens by producing antibodies that release histamine as a way to fight off foreign invaders. The release of histamine produces several reactions.

  • Inflammation – caused by the widening or swelling of the blood vessels to increase the blood flow to the area affected to speed up the healing process. This can cause nasal or earallergy1 canal congestion.
  • Fluid escaping from capillaries into surrounding tissue which most often shows as a runny nose and watery eyes and possibly excess fluid in the inner ear.
  • Mucous production to line and protect the area affected.
  • Constriction of smooth muscle such as the smooth muscle around the bronchi of the lungs. – making it harder to breathe.
  • Itch perception and skin rash – be cautious of using anything introduced into the ear such as cotton swabs.

These reactions can all cause discomfort and possible hearing loss for the duration of the exposure to the allergen.

How does the ear respond? 

The ear is divided into 3 distinct sections, inner, middle and outer. The allergy responses mostly affect the middle ear. The Eustachian tube which acts as a drainage tube and pressure release valve can become swollen. As well fluid or mucous can also build up, creating two concerns. One is a smaller drainage area and the second is the clogging of the drainage area.

This can lead to increased pressure with resulting discomfort or pain and less ability for the inner ear to transfer the sound waves necessary for hearing. It also can cause dizziness or light headedness. The combination of swelling and increased fluid can also promote a good breading ground for infection to begin which could lead to permanent damage.

What can you do to help prevent hearing loss?

Even if hearing loss caused by allergies is temporary this can be devastating to a child learning to speak. They may miss out on critical learning periods. To an adult this can lead to work place concerns of missed work or inability to hear properly on the job which could result in safety concerns or inability to understand directives given.

Having a full assessment by a qualified Audiologist is of high importance to access the extent of hearing loss and also rule out any other causes. Limiting exposure to known allergens or improving overall health to help the body handle exposures can all be positive steps to take. During acute allergic responses particularly if for longer durations of impaired hearing the hearing solution may be through the use of devices to aid in your hearing.

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

May 18, 2016

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
