A) Noise Resistance Ratings
Explanation:
The Noise Resistance Ratings (NRR) can be used as a unit of measurement with the aim of determining the effectiveness of the Personal Protective Equipment (PPE) to decrease sound exposure in a particular working environment. NRR determines the potential to reduce noise in decibels (dB), which is a measure used to indicate the power of the sound. Thus, it is possible to determine the efficiency of a given Personal Protective Equipment to block the sounds by reaching higher Noise Resistance Ratings.
