Understanding Noise-Induced Hearing Loss

Karl.B • Sep 28, 2018

Nearly 50 million Americans have hearing loss. Some factors that can lead to hearing loss include genetics, natural aging, illness, injury, or infection. However, millions of Americans suffer from noise-induced hearing loss, a totally preventable form of hearing loss that’s caused by exposure to excessively loud noises.

Noise-Induced Hearing Loss

Noise-induced hearing loss (NIHL) is one of the leading causes of hearing loss. We’re exposed to loud noises every day, from traffic noise to household appliances to your favorite workout track at the gym. Whether at home or at work, our environment is saturated with noise, and we’re always turning up the volume. While some sounds are perfectly safe, many of the sounds at work and in our recreational activities are far too loud, and can cause irreversible damage to your ears. NIHL is hearing loss that starts in your ears. The delicate cells in the cochlea, or fluid filled inner ear, that are responsible for picking up on the sound waves around you are easily damaged by loud noises. When they’re damaged or destroyed you will experience hearing loss, and once these cells die they don’t regenerate. You’ll experience permanent tinnitus or hearing loss that will affect the rest of your life.

How Loud is Too Loud?

If you’re asking if something is too loud, it probably is. Do you leave a concert with ringing in your ears, or tinnitus? Do you have to yell to be heard by the friend sitting next to you? If the answer is yes, then the sounds around you are far too loud, and you’re damaging your hearing.

Understanding Noise-induced hearing loss is all about the decibels (dB). Decibels are a way to measure sound volume, and the higher the number, the louder the sound. Some sounds are safe to listen to for many hours, and others can damage hearing in a matter of seconds. Sounds under 85 dB are considered safe, and unlikely to lead to hearing loss. Normal conversation, the hum of the refrigerator, or watching TV with the volume on low won’t cause hearing loss. However, many sounds are above 85 dB and will cause hearing loss.

NIHL can be sudden or gradual. If you’re exposed to one sudden, extremely loud sound like a gunshot at close range or fireworks a few feet away you’re hearing will be permanently damaged. Most commonly, NIHL is a gradual process, as the constant exposure to loud sounds chips away at your hearing health at work or during recreational activities.

Sounds that Cause Hearing loss

If you’ve left work feeling like sounds around you are muffled or faint, your body is telling you that the sounds were too loud, and were hurting your ears. You need to wear hearing protection, and step outside from time to time to give your ears a break. Some workplaces are extremely loud, with sounds from heavy equipment or machinery reaching up to 120dB. Working in this environment for a few minutes will cause permanent damage, and being exposed to these dB levels for an entire work day is deadly to your hearing health. Other sounds that can cause hearing loss are traffic noise, screeching brakes, and emergency sirens. Around the house, power tools, vacuum cleaners or leaf blowers are all loud enough to damage your hearing.

Protecting Your Ears from Noise-Induced Hearing Loss

While foam earplugs work in some situations, and are a great thing to have in your bag for emergencies, at work or during summer music festival season you don’t want to wear uncomfortable earplugs, and might choose to damage your hearing rather than putting in earplugs you don’t like.

Are Your Clinic-Sourced Baselines Being Entered in Your Database?

By Karrin Brandsen • 07 Feb, 2024

Baselines and their purpose: As an employer, it's important to understand the complete process of getting a baseline hearing test for your employees. A baseline test is the test that establishes an employee's benchmark for future hearing test comparison. In many cases, OSHA allows up to 6 months for this, but by doing it earlier, it allows any pre-existing hearing loss to be documented. After the baseline test, hearing tests are conducted at least annually to monitor for any changes in the employee's hearing health. Wait, there's a few more steps! After obtaining a baseline test, there are more steps that employers need to follow for compliance. Once the baseline test is complete, the results need to be sent to the provider of record (if contracted out) so that they can be screened for any problems and entered into your company's hearing conservation database. This way, any unclear data, possible STS (Standard Threshold Shift), or recordable STSs (shifts in hearing levels that are significant enough to be recorded on the injury log) can be identified. By following through with these steps, you can ensure your company is complying with this part of the OSHA requirements. Questions? Call today to find out more: 888.972.4420

Follow-Up Deadlines After Annual Testing

By Karrin Brandsen • 05 Jan, 2024

Follow -up on non-recordable and recordable STSs: As an employer, it’s critical that you take the necessary steps and follow up deadlines regarding employees’ hearing testing. If an STS, or standard threshold shift, is identified during a hearing test, OSHA requires employees to be notified of the results within 21 days and ensure they receive re-training. An STS occurs when an employee’s hearing threshold changes enough at 2000, 3000, and 4000 Hz in one or both ears, in comparison to their baseline audiogram. STS’s recordable on your OSHA-300 log should be done within seven days of the hearing test. Risks that come with STSs and ways to lessen the risk: If the STS meets recordability, it can negatively impact things like the company’s risk matrix. Even if the STS is non-recordable, OSHA still requires that the employer retrains the employee. However, you can avoid false STSs or recordable STS issues by ensuring that immediately preceding annual testing, employees have not had a cold, have not been listening to loud music, and have not been wearing earbuds. Earbuds are not typically suited to the industrial workplace because their level of sound can exceed 85 dB and are not typically ANSI-rated as hearing protection. Why Anadyne? By investing in quality hearing protection and mobile hearing testing services, you can save time and money while ensuring your employees’ safety and your companies productivity. At Anadyne, we offer a tag team system that allows production to continue while employees are being tested, reducing downtime and interruptions. Quality hearing protection is critical because, while throw-away earplugs may be cheaper upfront, they are only good for one use. Anadyne’s hearing protection steadily pays for itself after the first year and saves you money in the long run. Taking the extra time to invest in quality hearing protection and mobile hearing testing services is essential for protecting your employees and your company.

The Importance of Hearing Protection Fit Testing

By Karl Brandsen • 29 Sep, 2023

The hearing rating shown on HPDs packaging is often inaccurate. When it comes to protecting our hearing in noisy environments, we often rely on the ratings provided on the packaging of earplugs and other hearing protection devices (HPDs). These ratings can be deceiving and may not accurately reflect real-world performance. In fact, the figure on the packaging is nothing more than a rough estimate of the protection you’re actually getting. While some users might achieve the stated level of noise reduction, many do not. This disparity in real-world effectiveness has led experts to emphasize the need of hearing protection fit testing. Fit testing is the key to bridging the gap between laboratory estimates of attenuation and the actual attenuation achieved by workers as they wear their protectors in their daily routines. Fit testing is the key to bridging the gap between attenuation estimates and the actual attenuation. So why is fit testing so essential? The answer is simple: it’s the only way to determine how much noise reduction a person actually gets from their hearing protection device. As mentioned earlier, the rating on the packaging can be misleading. It might provide a point of comparison between different products, showing that Product A offers more or less protection than Product B. However, relying on this rating, even if it is de-rated to account for real-world use, is not reliable when protecting your hearing. One of the primary reasons for the wide range of attenuation provided by any given earplug is the uniqueness of each individual’s ear canal and the way they insert the device. Factors like ear shape, size, and the method of insertion can significantly affect the earplug’s performance. That’s why it’s important to test HPDs on the individuals who will be using them. Hearing protection fit testing involves assessing how well an earplug fits within an individual’s ear canal. By doing this, you can determine the actual protection that person is receiving from the device. Fit testing takes into account the real-world variables that impact effectiveness, such as the seal between the earplug and the ear canal. This method offers a much more accurate representation of the protection provided by the HPD, tailored to the specific user. In conclusion, if you work in a noisy environment or use hearing protection regularly, don’t rely solely on the rating displayed on the packaging of your chosen device. Instead, consider the importance of hearing protection fit testing. It’s the only way to ensure that you’re getting the level of protection you need to protect your hearing. Investing in proper fit testing will preserve your hearing for years to come. Want to know more? Contact an Anadyne rep today.

Who Missed Their Hearing Test?

By Wayne Brandsen • 14 Aug, 2023

Coordinating hearing tests. It's complicated. If you work in a large organization, you know there’s inevitably employee turnover and a continual flow of people coming and going. This can make things complicated when it comes to hearing tests. The new people need hearing tests and those that have left are probably still on a list somewhere from your last hearing test. This leaves your safety team with the headache of combing through old records to figure out who needs a hearing test next. You need a program. That program is one of the reasons Anadyne exists. It takes a program to screen through all the old records and new records; finding out when hearing tests that were last done, reviewing the current employment roster and the like. You’re now left with the complex reconciliation task of finding out who has been tested already this year, what legacy employees have not been tested, and what new employees you haven’t gotten any data on. What a headache! We can help. We have a program for that. Anadyne can provide a complete schedule, clear list of names and everything you need to answer questions; that is who needs hearing testing next. Our team will meticulously comb through all your records and create a comprehensive list of current employees, including when they had their last test and who has never had a hearing test. This allows us to do the next step of our program; figuring out who most urgently needs to be tested and creating a schedule accordingly. No need to panic when the bus comes back. Anadyne coordinates everything for you. Want to know more? Contact an Anadyne rep today.
