Ultrasonic sensor applications for Knowles Electret and MEMS microphones

Image of Knowles' Ultrasonic Applications OptionsKnowles microphones are used for receiving audible signals; several models are also used in ultrasonic applications. Knowles production line testing typically takes place at several frequencies up to 10 kHz. Therefore, the microphone specifications are also written with performance data up to 10 kHz but not beyond. While this is sufficient for ensuring the quality of the outgoing microphone, it does not mean that the microphone is limited to 10 kHz in practice. In this application note typical performance data up to 100 kHz is given for the microphone models most commonly used in ultrasonic applications.
