METHOD AND APPARATUS FOR TONAL ENHANCEMENT IN HEARING AID

摘要

An audio processing circuit tracks tonal components in an audio stream and enhances them by synthesizing matching tones, processing the matched tones, and mixing them in with the audio stream. A hearing assistance device, for example a hearing aid, includes such an audio processing circuit for enhancing the pitched or tonal parts of tonal sound such as speech or music.

主权项

1. A hearing assistance device, comprising:
a microphone configured to receive an acoustic signal including original tonal components; a receiver configured to receive an output audio signal and transmit an output sound representing the output audio signal; a processing circuit coupled between the microphone and the receiver, the processing circuit including a tonal enhancement circuit configured to extract the tonal components from the acoustic signal, enhance the extracted tonal components, and mix the enhanced tonal components with the acoustic signal including the original tonal components to produce the output audio signal.
