Systems and methods for assisting user with hearing by amplifying sound using an amplifier with gain and amplitude controls for a plurality of frequencies; and applying a learning machine to identify an aural environment and adjust the amplifiers for optimum hearing.

Articles and related devices and methods for fitting in-situ include a flexible sleeve, a housing assembly fixed to the flexible sleeve, a light source disposed within the flexible sleeve, and a photocurable resin contained within the flexible sleeve. The flexible sleeve may be elastomeric. A transducer may be disposed in the housing assembly.

The present disclosure relates to methods and apparatus for constructing and fitting a component that is designed to be worn at least partially within an ear canal. The methods and apparatus may be used in hearing aids such as receiver-in-canal hearing aids and completely-in-canal hearing aids. The techniques may also be use in constructing and fitting other devices including audio earbuds and ear plugs.

An ear-wearable electronic device includes a shell with a cable retention slot. The cable entrance slot has an interior end and an exterior end. A bend surface extends from the exterior end of the cable retention slot to an exterior surface of the shell. The bend surface aligned with a crux of a user's ear when the ear-wearable device is installed in an ear of the user's ear. The shell may include a uniquely-shaped outer surface that corresponds uniquely to an ear geometry of the user of the ear-wearable device.
