1. Apparatus configured for processing of both audible and ultrasonic sound inputs, comprising:
a sensor with a frequency response spanning both audible and ultrasonic frequencies; and processing electronics configured to separate the audible and ultrasonic input frequencies for independent use, and comprising a first filter configured to filter audible frequencies and a second filter configured to filter ultrasonic frequencies and a multiplexer for switching between the separated frequencies to provide a single output, the multiplexer allowing for simultaneous processing, by the processing electronics, of audible and ultrasonic frequencies output from the sensor, the processing including performing noise cancellation.
