Hearing Protection in the Workplace

The Importance of Hearing Protection in the Workplace: Safeguard Your Employees’ Well-being


According to the CDC, millions of workers are potentially exposed to damaging noise every year. Hearing loss is preventable, and employers are responsible for providing hearing protection to safeguard their workers. The threshold for providing protection is 85 decibels (dB). If you need to raise your voice to speak to someone 3 feet away, the noise may be over the threshold. Employers can use a calibrated sound level meter (SLM) to measure noise in the workplace and provide workers with personal noise dosimeters. OSHA standard 1910.95 states that employers must provide noise protection when sounds exceed 85 dB for eight hours. The article provides information on the requirements for hearing protection and the different types available.

Understanding the Threshold for Hearing Protection

The threshold for providing hearing protection in the workplace is 85 decibels (dB). If you find yourself having to raise your voice to communicate with someone standing just three feet away, it is likely that the noise level exceeds this threshold. Warning signs of excessive noise exposure include ringing or humming in the ears, having to shout to be heard, or experiencing temporary hearing loss after leaving work.

Measuring Noise Exposure

Employers can utilize a calibrated sound level meter (SLM) to measure noise levels in the work environment. For individual noise exposure, personal noise dosimeters can be provided to workers. These devices help in determining whether workers are exposed to elevated noise levels and need protection from overexposure.

OSHA Standards for Occupational Noise Exposure

OSHA standard 1910.95 addresses the issue of occupational noise exposure. It requires employers to provide noise protection for their employees when sound levels average above 85 dB over an eight-hour workday. Protection may also be required if sound levels exceed 85 dB for less than eight hours. Employers must first implement administrative and engineering controls to minimize noise before resorting to personal protective equipment (PPE) like earplugs and earmuffs.

Creating a Hearing Conservation Program

Employers with employees who are exposed to loud noise must establish and maintain a hearing conservation program in accordance with standard 1910.95(c). This program should include sound monitoring, notifications to employees about monitoring results, and regular audiometric testing. Employees should undergo baseline testing and annual testing to assess any hearing impairment or loss.

Selecting the Right PPE for Hearing Protection

Workers exposed to noise levels exceeding 85 dB over an eight-hour period should wear hearing protection. Employers should offer a variety of hearing protection devices (HPDs) to their employees and allow them to choose the ones that work best for them. Annual training on the proper use and care of HPDs should also be provided, along with information on the effects of noise on hearing and the purpose of audiometric testing.

Qualities of Effective Hearing Protection

Hearing protection devices (HPDs) are designed to reduce sound levels reaching the eardrum to below 85 dB. They should be considered as the last resort when engineering and administrative controls are not effective. HPDs are rated based on their noise reduction capabilities, known as the noise reduction rating (NRR). OSHA recommends reducing all NRRs by 50%, and NIOSH provides specific reduction factors for different types of HPDs.

The Types of Noise Protection

There are three main types of hearing protection: earmuffs, earplugs, and ear canal caps. Earmuffs provide the best noise protection and are worn outside the ears, while earplugs are worn inside the ears. Ear canal caps, also known as semi-inserts, do not offer as much protection but are useful in situations where hearing protection needs to be frequently taken on and off.

Choosing the Right Hearing Protection

The most effective hearing protection is one that workers are willing to wear consistently. It is important for workers to wear ear protection correctly, ensure proper fit, and select the appropriate protection for the specific noise environment. Allowing workers to choose their own hearing protection device increases the likelihood of proper usage. Factors that enhance worker acceptance of hearing protection include convenience, belief in their effectiveness, comfort, noise reduction capabilities, ease of fit, and compatibility with other personal protective equipment (PPE).

Managing PPE and Hearing Protection

Proper management of personal protective equipment (PPE), including hearing protection devices, is crucial for maintaining employee safety. Employing a digital process for equipment maintenance allows for scheduled inspections and automated alerts to ensure equipment is in optimal condition. This comprehensive approach to safety management helps to protect workers’ hearing and overall well-being.
