The Science Behind Noise Reduction Rating and its Importance in Various Industries
Understanding Noise Reduction Rating (NRR)
Noise Reduction Rating (NRR) is a measure of the effectiveness of hearing protection devices in reducing noise exposure. It quantifies the level of noise reduction provided by a specific device and is expressed in decibels (dB). The higher the NRR, the greater the potential for noise reduction.
For example, if a device has an NRR of 25 dB, it means...
