Description
A sound level meter is a self-contained hand-held instrument with an attached microphone and a built-in display device.
The Part 1 is an International Standard that provides specifications for sound level meters.
It gives electro acoustical performance specifications for three kinds of sound measuring instruments:
- A time-weighting sound level meter that measures exponential-time-weighted, frequency weighted sound levels
- An integrating-averaging sound level meter that measures time-averaged, frequency weighted sound levels
- An integrating sound level meter that measures frequency-weighted sound exposure levels
Sound level meters conforming to the requirements of BS EN 61672-1 have a specified frequency response for the sound incident on the microphone from one principal direction in an acoustic free field or successively from random directions.
Sound level meters specified in BS EN 61672-1 are intended to measure sounds in the range of human hearing.
Specifications in BS EN 61672-1 for the response to sound waves apply without an operator present in the sound field.
