Instantaneous Noise Survey. An instantaneous noise survey is used to document the operating noise levels for each piece of equipment. This helps a mine operator define any equipment that exceeds 115 dBA a level to which no miner shall be exposed for any period of time per MSHA as well as identfying equipment that might result in more exposure .
