| The Avisoft Bioacoustics electret
ultrasound microphone is a cost-effective model that employs an SPM-series
electret capsule by Knowles. It is very compact, durable (no
need to replace diaphragms) and is also relatively immune against
humidity. The moderate sensitivity and relatively poor flatness of
the frequency response is still acceptable for many applications.
