A new design for an implantable hearing aid

J A Nunley, J Agnew, G L Smith

ISA Transactions

|January 1, 1976

Summary

A novel totally implantable hearing aid, designed to work with residual hearing, is being tested. This innovative device amplifies sound by driving the ossicular chain, addressing limitations of previous designs.

Background:

Previous totally implantable hearing aids have presented significant disadvantages.
A need exists for advanced hearing solutions that integrate with natural auditory function.

Purpose of the Study:

To introduce and evaluate a novel totally implantable hearing aid.
To assess the efficacy of a device that mimics natural hearing mechanisms.

Main Methods:

Surgical implantation of the new hearing aid device in chinchillas.
Evaluation of the device's performance in conjunction with residual hearing.
Assessment of amplified drive to the ossicular chain.

Main Results:

Successful implantation and preliminary testing of the novel hearing aid.
Demonstration of the device's ability to augment the natural hearing process.
Data on the audiological outcomes and device functionality.

Conclusions:

The new totally implantable hearing aid shows promise in addressing limitations of existing devices.
The device's design, paralleling natural hearing, offers a new approach to auditory restoration.
Further research and development are warranted based on initial findings.
