This sound meter has been designed to check compliance with safety regulations and perform acoustic analysis by safety engineers, health, industrial and safety offices as well as quality control. It offers a PC interface for downloading data capability. Uses 2 different weighting filters required by the IEC651 and ANSI S1.4 Type 2 for audio filtering. The A weighting 30~130dB is good for general low to moderate ambient noise sound level and the C weighting 35~130dB for measuring sound level of acoustic material control in various environments eg. loud low-frequency background noise.
