Abstract: The disclosure relates to a hearing device comprising an earpiece provided with a vent configured to provide for a venting of sound waves between an inner region of the ear canal and an ambient environment outside the ear canal; the earpiece further comprising an acoustic valve including a valve member moveable relative to the vent between different positions and an actuator configured to provide an actuation force for a movement of the valve member such that an effective open cross-sectional area of the vent can be modified by the movement of the valve member; the hearing device further comprising an output transducer configured to be acoustically coupled to the inner region of the ear canal.

Abstract: An in-ear hearing device includes a light source configured to emit light, a photodetector configured to detect the emitted light after the emitted light passes through tissue of a subject, a spout; an audio receiver configured to deliver a sound to the subject through the spout, and a dome configured to conform to a shape of a subject's ear canal when the hearing device is in the ear canal. An output of the light source and an input of the photodetector are separated by the dome, and the dome absorbs and/or reflects at least part of the emitted light. The photodetector may be a forward biased photodiode. The sensor device can be realized with power levels, circuitry components, and in package sizes, of hearing devices.

Abstract: A customized in-ear hearing device includes a light source, photodetector, light emission window, and light transmission window. The light source and the photodetector together function as a physiological sensor by emitting light from the light source through the light emission to the skin of a user's ear canal, and detecting at the photodetector light reflected by the skin that passes through the light detection window. The light emission window and light detection window are located at a customized portion of the sidewall of the device that contacts the skin in the ear canal.
