Abstract
Apparatus and method for determining an operating state of a personal acoustic device by receiving signal from first and second movement sensors indicating movement detected by each, wherein the first movement sensor is disposed on a portion of the personal acoustic device structured to be worn on a user's head to enable the first movement sensors to detect movements of a user's head when the personal acoustic device is in position on the user's head such that a casing of the personal acoustic device is adjacent an ear of the user, and wherein the second movement sensor is disposed on a portion of the personal acoustic device structure to not be worn on a user's head.
