Abstract
A device for providing hearing enhancement and hearing protection. The device includes a means to amplify sounds that do not exceed a specified sound threshold limit. The sound output is restricted to a non-harmful range so that loud, burst full sounds are limited to a safe range and weaker sounds are enhanced for hearing.
Claims1
A hearing device comprising:
- a case configured to fit in an ear canal;
- a microphone disposed near the exterior end of the case and positioned to receive exterior sounds;
- a speaker disposed near the interior end of the case and positioned to transmit interior sounds;
- and
- an electronic circuit connected with the microphone and the speaker, the circuit having a threshold level and configured to produce amplified exterior signals from the exterior sounds by fixed increments that do not exceed the threshold level,
- wherein the amplified exterior signals are converted to the interior sounds and emerge from the speaker at or beneath the threshold limit.
