Hearing Protection

Life Can Be Loud

To prevent adverse outcomes of noise exposure, noise should be reduced to acceptable levels. The best method of noise reduction is to use engineering modifications to the noise source itself, or to the workplace environment. Where technology cannot adequately control the problem, personal hearing protection should be considered as an interim measure while other means of reducing workplace noise are being explored and implemented.

As a first step in dealing with noise, workplaces need to identify areas or operations where excessive exposure to noise occurs.

How can I tell if my workplace is too loud?

If you answer yes to any of the following questions, the workplace may have a noise problem:

  • Do people have to raise their voices?
  • Do people who work in noisy environments have ringing in their ears at the end of a shift?
  • Do they find when they return home from work that they have to increase the volume on their car radio higher than they did when they went to work?
  • Does a person who has worked in a noisy workplace for years have problems understanding conversations at parties, or restaurants, or in crowds where there are many voices and "competing" noises?

If there is a noise problem in a workplace, then a noise assessment or survey should be undertaken to determine the sources of noise, the amount of noise, who is exposed and for how long.

Hearing protector effectiveness is specified by a Noise Reduction Rating (NRR), typically ranging from 15 to 35 decibels. In practice, the average protection achieved is about 10 to 20 decibels, depending on the fit and proper wear. Try different devices from a wide variety of hearing protectors:

  Validation - Fit Test Your Hearing Protectors

Protecting workers from hazardous noise levels is an ongoing challenge for many organizations. In fact, the most commonly recorded occupational health issue in the manufacturing sector is permanent hearing loss. The success of your safety program depends on many factors and requires more than just offering hearing protection.

The E-A-Rfit Dual-Ear Validation System measures the effectiveness of the hearing protection from inside the employee’s ear, providing accurate, quantitative results. And because you can simultaneously test both ears, you’ll have more time to educate employees on the importance of fit and compliance.

A Rule of Thumb

When you feel the need to shout in order to be heard three feet away, the noise levels are probably 85 dBA or more and hearing protectors are recommended.
