Abstract

This article introduces the constraints and issues related to the implementation of a binaural localization algorithm on a pair of hearing aids. The algorithm should improve the rendering of the spatial information available in the audio signals, which are usually distorted by the signal processing algorithms in the hearing devices, thus degrading localization cues. First, several reported algorithms achieving binaural sound localization in the frontal horizontal plane are reviewed. The way in which the standard methods and processes could be used within the context of hearing aids is then discussed. Finally, a solution that is suitable for a certain type of systems is proposed.

Hearing aid

A hearing aid is a device designed to improve hearing by making sound audible to a person with hearing loss. Hearing aids are classified as medical devices in most countries, and regulated by the respective regulations. Small audio amplifiers such as personal sound amplification products (PSAPs) or other plain sound reinforcing systems cannot be sold as "hearing aids". Early devices, such as ear trumpets or ear horns, were passive amplification cones designed to gather sound energy and direct it into the ear canal.

Hearing

Hearing, or auditory perception, is the ability to perceive sounds through an organ, such as an ear, by detecting vibrations as periodic changes in the pressure of a surrounding medium. The academic field concerned with hearing is auditory science. Sound may be heard through solid, liquid, or gaseous matter. It is one of the traditional five senses. Partial or total inability to hear is called hearing loss.

Hearing loss

Hearing loss is a partial or total inability to hear. Hearing loss may be present at birth or acquired at any time afterwards. Hearing loss may occur in one or both ears. In children, hearing problems can affect the ability to acquire spoken language, and in adults it can create difficulties with social interaction and at work. Hearing loss can be temporary or permanent. Hearing loss related to age usually affects both ears and is due to cochlear hair cell loss. In some people, particularly older people, hearing loss can result in loneliness.
