Description Decibel Meter for Safety Compliance Applications The FNIRSI FDM01 Decibel Meter has been designed to check noise compliance with safety regulations. It is used to perform acoustic analysis by safety engineers, health, industrial and safety officers as well as sound quality control in environments like factories, and offices, where traffic noise needs to be monitored and for any other noise monitoring applications. The FDM01 Sound Level Meter features Fast and Slow measurement switching. Fast measurement is more sensitive and picks up on fast-changing noise levels. Slow measurement is more stable and able to pick up on lower frequencies.
