Abstract
Herein provided is a method for acoustical switching suitable for use with a microphone enabled electronic device. The method includes capturing a first microphone signal from a first microphone on a device, analyzing the first microphone signal for a contact event versus a non-contact event, and directing the electronic device to switch a processing state responsive to detection of either the contact event or non-contact event. In another configuration, additional microphone can be added for performing coherence analysis between at least two microphone signals mounted on or in the device. At least one parameter settings of the device can be changed in response to at least one detected physical contact on the device. Other embodiments are disclosed.
