NALguide: Hearing Aid Features Explained

This guide has been designed to support people in exploring the hearing aid features that could be used for their listening needs, and discuss them with their family and clinician. Clinicians can refer to this guide to better support the early stages of the client’s journey, and when reviewing hearing goals and new technologies.

A wide range of hearing aid features has been broken down into six categories based on common listening needs.

This NAL research project was funded by the Australian Department of Health and Aged Care and done in collaboration with Deafness Forum Australia and the Hearing Aid Manufacturers and Distributors Association of Australia (HAMADAA).
