Hearing Protection Headset HD-10
Hearing protectors can be recommended for protection against the harmful effects of impulsive noise. The noise reduction rating (NRR) is based on attenuation of continous noise.

The noise level (dB) to which you are exposed while wearing a hearing protector can be estimated by subtracting the NRR from the measured work place noise level.
