What is a sound level meter?
A sound level meter is an instrument designed to respond to sound in approximately the same way as the human ear. The purpose is to give objective, reproducible measurements of sound pressure level (SPL).
The terms sound level meter and noise level meter are commonly used to describe the same instrument. The principal difference, when talking about sound level meters, is the classification of measurement accuracy, as defined by international standards. Naturally, all Brüel & Kjær sound level meter instruments comply with the highest national and international standards.
