At what dB level is an employer required to have a hearing conservation program in place?

85 decibels

Who needs to be in a hearing conservation program?

According to the standards, a hearing conservation program is required “whenever employee noise exposures equal or exceed an 8-hour time-weighted average sound level (TWA) of 85 decibels measured on the A scale (slow response) or, equivalently, a dose of fifty percent.

What does a hearing conservation program include?

The important elements of the program include baseline audiograms, annual audiograms, training, and followup procedures. Employers must make audiometric testing available at no cost to all employees who are exposed to an action level of 85 dB or above, measured as an 8-hour TWA.

What is the lowest level of noise that can cause hearing loss?

Sounds at or below 70 A-weighted decibels (dBA), even after long exposure, are unlikely to cause hearing loss. However, long or repeated exposure to sounds at or above 85 dBA can cause hearing loss. The louder the sound, the shorter the amount of time it takes for NIHL to happen.

What type of hearing protection is best?

How do I choose hearing protection?

Three Tips for Choosing the Right Hearing Protector

1) Know How Much Noise Reduction You Need. Obviously, the first consideration in choosing a hearing protector is whether it will block enough noise to reduce your exposure to a safe level.
2) Think About Your Worksite and Job Tasks.
3) Decide What is Most Comfortable and Convenient.

This means that ear plugs are suitable when you need the highest levels of protection, for instance in very loud workplaces such as factories, airports, and foundries. Ear plugs are also very light and easy to carry.

Is a higher dB rating better?

Noise Reduction Rating (NRR) is a measure of the effectiveness of a hearing protection device to reduce noise levels. Higher values indicate greater noise reduction.
