從聽障生口語復健目標看助聽器材的「不能」

助聽器材的使用和口語教學已成為國內聽覺障礙的復健的主要作法。然而，聽障復健走向高科技並未解決或減輕這些學生的溝通障礙。本文以聽的層次及口語聽辨所需的聽能，比對助聽器材的放大功能和助聽器科技對聽力復健之缺乏掌控，說明在聽障的復健上，助聽器材的使用長期被家長賦予過高的期待，並指出在時下以多數聽障生都在普通班受教的狀況下，實有必要多開發與利用電腦口語訓練輔具，以利課外自學。

Fitting hearing-impaired students with hearing instruments and placing them in oral-only educational programs have been the two pillars in local auditory rehabilitation programs. This article argues that such a practice is inadequate by delineating the listening tasks and the fundamental auditory abilities involved in speech perception. These abilities are examined against the basic amplification function of the hearing instruments as well as the lack of full control of the outcome as prescribed by the hearing aid fitting methods. Together， the results from the psychoacoustic research presented in this article point to the imminent needs of searching for rehabilitation resources such as auditory and speech/language training provided via computer software that facilitates self-learning.
