Therefore, the following Classes of hearing protectors are A, AL, B, BL, or C. The L classification associated with Class A or B (i.e. AL or BL) means that the hearing protection device attenuates at least 20dBA when tested at 125Hz. This is an important factor when choosing hearing protection for low frequency noise.
What is class A hearing protection?
Class A — used when noise exposure levels are between 95 dBA (Lex) and 105 dBA (Lex). Generally, hearing protectors with a noise reduction rating (NRR) of 24 will fit into this category. The noise reduction rating lists the amount of decibels that the protectors will reduce the noise levels.

What makes a loud noise in the workplace?
In the workplace, these types of sudden loud noises often come from machine presses that are used to shape metal or other objects. This type of extreme noise hazard can easily surpass 120 dB—the louder the noise is, the more damaging it will be. However, as with all noise pollution, proximity to the noise determines how loud it will be. Any facility that has machines or other objects that cause sudden loud noises will need to make sure there are signs nearby reminding employees of PPE requirements.

What are the risks of hearing loud noise?
There are two types of hearing risks associated with loud noise. The first is a sudden spike in loud noise—things like gunshots or explosions fall into this category. The other is prolonged noise exposure that is significantly louder than normal.
When is double hearing protection required?
Double protection is necessary when the attenuation of a singular hearing protection device is not enough to ensure adequate protection for the wearer. Let’s review a few situations in which a single hearing device would be insufficient. According to NIOSH, any worker whose 8-hour time-weighted average exposure exceeds 100 dBA should wear double hearing protection. Double hearing protection is also required in mining operations governed by the Mine Safety and Health Administration for noise exposures in excess of 105 dBA for an 8-hour time-weighted average.
Why do you need double hearing protection?
One downside to wearing double protection is that it may put the worker in harm’s way should he or she be unable to hear warning sounds in the surrounding area. For this reason, double hearing protection should be carefully considered for certain worksites.

A key element of ensuring you’re achieving the highest decibel protection when wearing earplugs as a part of your dual hearing protection is understanding the impact their fit has on effectiveness: To receive the highest protection, the earplug must be worn properly.
What Is Occupational Hearing Loss?
Occupational hearing loss is damage to your hearing that occurs due to exposure to loud noise at work. Hearing loss from noise exposure can be temporary or permanent and can occur in one or both ears. Symptoms of occupational hearing loss include ringing in the ears (tinnitus), difficulty understanding speech, and increased sensitivity to sound.
What Are OSHA Hearing Protection Requirements?
OSHA’s hearing conservation regulations protect workers from noise-related hearing loss. The regulations require employers to reduce noise exposure and provide workers with hearing protection if noise levels exceed certain limits.
How Loud Is Too Loud?
The level of noise is measured in units called decibels (dB). OSHA’s hearing conservation regulations apply to workers exposed to an average noise level of 85 dB or higher over an eight-hour workday.
Hearing Conservation Program
The goal of the hearing conservation program is to prevent noise-induced hearing loss among workers. Employers must implement a hearing conservation program if any employee is exposed to an average noise level of 85 dB or higher over an eight-hour workday. The program must include:
Occupational Noise Exposure
OSHA’s noise exposure standards are based on a worker’s time-weighted average (TWA) noise exposure over an eight-hour day. The TWA is the average noise level over eight hours, with any sound above 115 decibels (dB) being considered harmful.
Types of Hearing Protection Devices
There are two main types of hearing protection devices: earplugs and earmuffs. The earplugs create a seal in the ear canal blocking all sound from entering. Earplugs are available in both disposable and reusable varieties. Earmuffs fit over the ears and create a barrier between the noise and the ear.
Conclusion
OSHA’s hearing conservation program protects workers from noise-induced hearing loss. The program includes noise monitoring, training on the dangers of noise exposure, free annual hearing exams, and hearing protection for employees exposed to loud noise.
What is the OSHA number?
If you have any further questions, please feel free to contact our [Office of Health Enforcement] at (202) 693-2190.
Do hearing protectors have to be replaced?
The employer must ensure proper initial fitting and supervise the correct use of all hearing protectors. Hearing protectors must be replaced as necessary, and their replacement must also be paid by the employer. All types of personal protective equipment have a limited life span.
Do earplugs lose elasticity?
The foam seal that surrounds the ear on earmuffs, the flanges on rubber earplugs, and body of foam earplugs, all lose their elasticity. As hearing protectors wear out, their attenuation properties are diminished; the head band on earmuffs also can relax so that the muff no longer provides a snug fit.
Do plugs need to be replaced?
Plugs that cannot be cleaned must be replaced. The replacement requirement primarily relates to normal wear and tear, but it would also include situations where the nature of the workplace or the nature of an employee's duties makes some accidental loss of hearing protectors reasonably predictable.
