Noise Reduction Rating (NRR)

Purpose

The Noise Reduction Rating (NRR) is a numerical value assigned to hearing protection devices (HPDs) to indicate their effectiveness in reducing the noise exposure of a worker. The purpose of the NRR is to provide a standardized system for employers and workers to compare the noise-reducing capabilities of different HPDs.

Calculation

The NRR is calculated by measuring the attenuation (reduction) of a hearing protector device in decibels (dB) across a range of frequencies. The attenuation is measured using a specialized instrument called a sound level meter, which is calibrated to simulate the human ear’s frequency response.

The NRR is determined by taking the average of the attenuation measurements obtained at the frequencies of 1000, 2000, and 3000 Hz. The NRR value indicates the number of decibels of noise reduction provided by the HPD. For example, an HPD with an NRR of 25 is expected to reduce the noise exposure of a worker by 25 dB.

It is important to note that the NRR is only an estimate of the effectiveness of an HPD and should not be used as the sole basis for selecting a particular device. Other factors, such as the specific noise environment, the duration of exposure, and the individual’s personal preferences, should also be considered when selecting an HPD.
