Abstract
An exemplary passive acoustic proximity detection system is configured to determine a first acoustic spectrum of a first signal representative of audio detected and output by a first microphone configured to be positioned at an ear canal entrance of a user. The detection system is further configured to determine a second acoustic spectrum of a second signal representative of audio detected and output by a second microphone configured to be located away from the ear canal entrance. Based on a comparison of the first acoustic spectrum and the second acoustic spectrum, the detection system is configured to generate a proximity indicator indicative of a proximity of an object to the first microphone. Based on the proximity indicator, the detection system is configured to select a signal processing program for execution by the passive acoustic detection system.
