Abstract
An in-ear device includes a housing shaped to hold the in-ear device in an ear, and an audio package, disposed in the housing, to emit sound. A tympanic membrane measurement unit (TMMU) is structured to measure a movement of a tympanic membrane in the ear caused by external sound received by the tympanic membrane, and a controller is coupled to the audio package and the TMMU. The controller includes logic that when executed by the controller causes the in-ear device to perform operations. The operations include measuring a movement of the tympanic membrane, and in response to measuring the movement of the tympanic membrane, outputting sound from the audio package to destructively interfere with the external sound received by the tympanic membrane.
