  Noise reduction rating (NRR) is a measurement of how well a device or material can reduce sound or noise. The requirements for a noise reduction rating can vary depending on the type of device or material and the level of noise reduction needed. NRR is usually measured in decibels (dB) and is a standard set by the American National Standards Institute (ANSI) and the Occupational Safety and Health Administration (OSHA) .
