Although the electronic performance of Inductive loop and other hard of hearing assitive audio systems is well covered by appropriate criteria and codes of practice, little or no attention appears to have been given to the acoustic performance and requirements of such systems. The paper reports the results of acoustic performance testing carried out on a number of HoH systems and components. In particular, the effects on the clarity and intelligibility of speech picked up by a system's microphones are discussed. The parameters such as microphone type, orientation, location & distance from a talker are all shown to have a significant effect on the resultant performance. The paper concludes by making recommendations for test procedures and design criteria targets for the acoustic & intelligibility performance of such systems.
