What Is Occupational Hearing Loss?
Occupational hearing loss is damage to the inner ear due to the noise or vibrations from some jobs. Conditions in the workplace can cause this damage, whether through exposure over time or some type of sudden trauma. While the main symptom is hearing loss, accompanying issues can include tinnitus, dizziness, depression, anxiety, sleeplessness, and trouble concentrating. Most cases of occupational hearing loss occur gradually over time and display no obvious physical changes, which can make it difficult to recognize as it is happening. In some cases, short-term exposure can result in short-term loss. The employee can regain hearing after a period of rest. In many other cases, however, the hearing loss is permanent. This may not mean that an employee becomes deaf, though that is sometimes the case. The severity of the hearing loss can vary, and even slight loss can still affect a worker’s life significantly.Many Types of Noises Can Cause Occupational Hearing Loss
Exposure to all different types of noise and sounds can result in permanent hearing loss. Some of these sounds are more obvious, such as the noise from a jackhammer or the roar of heavy machinery. But even softer sounds, if still above certain levels, can damage the ear. Noise is measured in decibels, which monitors both the loudness and strength of the vibrations cause by sound. Any sound above 80 decibels can cause harm, and experts suggest the use of ear protection at 85 decibels, especially if the exposure will be prolonged. To better understand the level of noise, some common sounds measure at:- 80dB: heavy traffic
- 90 dB: a vacuum or a food blender
- 100 dB: a rock concert or a sporting event
- 120 dB: an ambulance siren or a thunderclap
- 130 dB: a shot from a rifle
- Construction workers
- Manufacturers
- Miners
- Ambulance drivers
- Air traffic controllers
- Sanitation workers
- Carpenters
- Landscapers
How to Protect Yourself From Work-Related Hearing Loss
As previously mentioned, hearing loss often happens gradually, and the worker may not realize damage is being done until it is too late. Often, the first sign that alerts a person to hearing loss is difficulty hearing another speak. Too many times, irreparable damage has already been by that time. To protect yourself from occupational hearing loss, it is a good idea to:- Wear ear protection.
- Get your hearing checked regularly.
- Talk with your employer about workplace noise.
Employers Have Certain Responsibilities to Help Protect Employees
The Occupational Safety and Health Administration (OSHA) requires that employers take steps to help prevent occupational hearing loss among employees. Some of those mandates include:- Employers must monitor noise levels to accurately identify those employees are exposed to noise over 85 dB.
- Employers must repeat or adapt monitoring if there are any changes in production, process, or controls that could affect noise levels.
- Employers must establish and utilize an audiometric testing program to help monitor the hearing of employees.
- Employers must fit (or re-fit) employees with hearing protectors and show the employee how to use them properly.
