Classroom Speech Reinforcement
Disability Access for
We have been deeply involved in the promotion of improved acoustical and sound system standards for schools and universities as part of a program to help provide a comfortable and helpful acoustical environment for people with hearing impairment. Lower background noise and shorter reverberation times are important components of providing usable speech intelligibility for people with moderate hearing impairment. We design and specify listening assistance systems for compliance with the Canadian and American building code requirements for access by people with hearing impairment. We also evaluate and identify sources of EMI (Electro-Magnetic Interference) that can hamper the use of hearing aid T-Coil settings with telephones and listening assistance neck loops.
Hearing Impaired Persons
We have presented special workshops and seminars to a variety of groups, including audiologists, end-users and product manufactuers outlining the issues related to speech intelligibility, room acoustics and sound system installation and design.
We presented at the February 98 IHEAR Conference in Vancouver, describing the issues behind sound system design for critical speech intelligibility work, and showing how poor sound system design can replicate the frequency response of ears with hearing loss in the critical intelligibility bands.
