碩士 === 國立臺北科技大學 === 電機工程系所 === 105 === This thesis focuses on the compatibility improvement between wireless communication device and hearing aids which is defined by American National Standard Institute, (ANSI) in 2011. To resolve the compatible issue is based on the original hardware architecture, The improved mothed which are proposed to resolve those problems effectively. The first one is to enhance the electromagnetic field energy. The last one, the audio optimized tuning is considered to fix this issue. Owing to the small size of cell phone’s receiver, the hearing aid compatibility testing results cannot meet the Telecoil T4 rating for AT&T’s specification. This thesis improve the hearing aid compatibility testing results from T2/T3 rating up to T4 rating by adding the Telecoil hardware, and using the audio DSP platform to tune the audio frequency response. According to the experimental results, the proposed method works correctly. One can obtain a better experience with the modified hearing aid device for voice communication call.
