HAVE YOU BEEN SET UP? A WORKSHOP ON THE ART OF COUPLING AN ACOUSTIC CALIBRATOR TO A SOUND LEVEL METER.

摘要

In order to measure sound pressure levels with a sound level meter, it is necessary to ensure that the meter is correctly adjusted for the conditions under which it will be measuring. This is normally effected by applying an acoustic calibrator to the microphone in the configuration the meter will be used, and adjusting the meter as required to match the level of the calibrator. The act of adjustment is usually simple; knowing the level to adjust it to is not always so. This workshop session is aimed at showing all the factors that should be considered, and what can happen if they are not.
