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.

Hearing device with optical sensor at spout

A cerumen protection plug for a hearing device. The cerumen protection plug prevents cerumen from passing along a sound conduit in the hearing device and blocking sound output from a receiver in the hearing device. The cerumen protection plug includes a circular plug containing a cerumen barrier. A positioning handle allows the cerumen barrier to be positioned along the sound conduit, where it prevents cerumen that has entered the sound conduit from traveling along the sound conduit to the receiver or an output port of the receiver.

Cerumen protection plug

A tool for replacing a cerumen filter in a sound conduit of a hearing aid. The tool is designed to position a cerumen filter along the sound conduit and to couple with and remove a cerumen filter that has been positioned along the sound conduit. The tool comprises an insertion tip and an removal tip, both configured to fit inside the sound conduit and to couple or engage with an engagement body extending centrally from the cerumen filter. The tool may be in the form of a stylus with the insertion tip on one and the removing tip on the other end. The tool may also be in the form of a disc dispenser with a plurality of insertion and removal tips attached to the dispenser and accessible for use by rotating plates making up the disc dispenser.

Cerumen filter applicator

A method of customizing a component of a hearing device to the ear of a hearing device user. The method includes the steps of providing the hearing device component as a pre-form including a shape-memory material, heating the hearing device component, and bringing the hearing device component in contact with at least a portion of the ear after reaching a pre-set contact temperature such that the hearing device component conforms to the individual shape of the at least a portion of ear. The shape of the hearing device component is fixed by attending a hardening time of the shape-memory material. Therefore, the hearing device component perfectly fits to the geometry of the user's ear canal.

The present invention relates to an encapulated hearing device (), e.g. for long-term wear, in which an electronics module () is encapsulated into a thermoformed hull () by means of an appropriate adhesive (). This thermoformed hull () acts as an improved barrier between the electronics module () and the environment of the inner ear, reducing the risk of moisture reaching electrical components.
