英文摘要
DESCRIPTION: (Adapted From the Applicant's Abstract) The applicant
organization has discovered and experimentally observed that an
Electroacoustical Compensation (ELAC) circuit counteracts the occlusion
effect experienced by hearing aid wearers of unvented hearing aids.
Unvented hearing aids with the ELAC circuit show promise for a significant
improvement over present vented designs in the following areas: 1) Higher
available gain before positive feedback oscillation, 2) Reduced amplifier
and receiver distortion, 3) Reduced direct transmission of ambient noise,
4) Better low-frequency response (if needed), 5) Better suited for
in-the-canal devices.
In view of the seven-year involvement with occluded in-the-ear
communication device design based on ELAC circuit, the applicant will be
able to design, fabricate, and perform a limited evaluation of ELAC
hearing aids within the limited time and resources of the proposed Phase I
study. All facilities are in place.
