Hearing Protection Devices

When sound level exposure exceeds 90 dB usually some method of hearing protection is required. When administrative and engineering controls are insufficient, then PPE in the form of a hearing protection device should be used. Hearing protection devices come in two varieties:

  • Ear Plugs
  • Ear Muffs

Ear plugs are generally used for most situations where hearing protection is needed due to their ease of use and low cost. When choosing ear plugs be sure to select a variety that is a comfortable fit for your ear canal.

Ear muffs are used when a higher than usual level of protection is needed. When using ear muffs you need to be sure you obtain a tight seal between your head and the muff in order to achieve the necessary level of protection.

For further information on the Hearing Protection Program refer to the hearing protection section under General Safety, or the Hearing Conservation Program Manual.
