When is workplace hearing protection needed?
What is NRR?
The OSHA permissible exposure limit (PEL) is 90dB
The NRR, or Noise Reduction Rating, of a hearing over an eight-hour period. The actual level, however,
protection device is the amount of decibels by which it is 85dB. That means that if a time-weighted average
will reduce noise exposure. For example, if a worker was noise level exceeds 85dB, you need a hearing
exposed to 100dB of noise and was given a pair of ear conservation program. Shorter time periods allow
plugs with a NRR of 25dB, that worker would be exposed higher noise levels – but exposure to noise levels
to a time-weighted average of 82dB, or [100dB - (NRR-7)]. of 115dB or higher require hearing protection.
