摘要

传统上，助听器安装的目标是使语音的声学水平高于受损耳朵的听力阈值。线性放大通常足以使语音的整体水平高于阈值。不幸的是，语音的信息承载，但低水平，高频频谱成分往往没有得到线性助听器足够的放大，以确保其可听性。

Adaptive High Pass Filtering with Expansion

Traditionally, the goal of a hearing aid fitting is to bring the acoustic level of speech above the hearing threshold of the impaired ear. Linear amplification is usually sufficient to bring the overall level of speech above threshold. Unfortunately, the information-bearing;, but low level, high frequency spectral components of speech often do not receive sufficient amplification from linear hearing aids to ensure their audibility.
