Abstract Previous research has shown the benefit to hard of hearing people of using magnetic induction ('T' -switch) to couple their hearing aids to telephone receivers. Benefit provided by receiver amplification in the telephone handset has also been shown. Informal surveys of hard of hearing people indicate that many of them use telephones having a dual capability, namely, magnetic coupling and receiver amplification. The objective of this investigation was to study user performance with this dual capability. In particular, the effect of receiver amplification on the speech perception ability of hard of hearing subjects using inductive means to couple their hearing aid to a telephone receiver was investigated under both good and poor telephone line conditions. Results show that the use of receiver amplification in conjunction with inductive coupling significantly improves subjects' speech perception scores under all the conditions tested. Clinical implications and recommendations are discussed.

Des recherches ont montré l'avantage qu'il y a, pour les malentendants, à utiliser l'induction magnétique (télécapteur) pour coupler leur prothèse auditive à un récepteur téléphonique. L'avantage de l'amplification dans le combiné a également été démontrée. Des sondages informels menés auprès des malentendants indiqient que bon nombre d'entre eux utilisent des téléphones à double capacité, à savoir le couplage magnétique et l'amplification. Cette recherche avait pour but d'étudier la performance de l'utilisateur avec cette double capacité. Plus particulièrement, on a étudié l'effet de l'amplification sur la capacité de perception de la parole chez les malentendants, en utilisant un couplage inductif pour coupler leur prothèse auditive à un récepteur téléphonique, et ce dans de bonnes conditions et dans de mauvaises conditions de ligne téléphonique. Les résultats montrent que l'utilisation de l'amplification, de concert avec le couplage inductif, améliore sensiblement la capacité de perception de la parole, des sujets, dans tout les conditions testées. On discute également les implications et les recommendations cliniques pertinentes.
