Tips: What is a sound level meter?
Sound level meter is the most basic noise measuring instrument. It is an electronic instrument, but it is different from objective electronic instruments such as voltmeters. When the acoustic signal is converted into an electrical signal, it can simulate the time characteristic of the human ear's response speed to the sound wave; the characteristic of different sensitivity and the intensity characteristic of changing the characteristic when the loudness is different. The sound level meter is a subjective electronic instrument.
