Microphone E-mail
Measurement microphones are used in sound analysis meters, noise measurement (in public nuisance abatement contexts), acoustic laboratories, loudspeaker design and quality control work, etc. They are made with greater care than most microphones and generally come with a calibration certificate. However, like most manufactured products there can be variations, which may change over the lifetime of the device. Accordingly, it is regularly necessary to test the test microphones. This service is offered by some microphone manufacturers and by independent certified testing labs. Some test enough microphones to justify an in-house calibration lab. Depending on the application, measurement microphones must be tested periodically (every year or several months, typically) and after any potentially damaging event, such as being dropped (most such mikes come in foam-padded cases to reduce this risk) or exposed to sounds beyond the acceptable level.
