This book will sell particularly owing to the increasing number of people in older age groups of the population in industrialised countries, which means that the number of people with some degree of hearing impairment is also increasing. Recent legislation in many of these countries requires the use of technology to enhance the access of hearing-impaired and deaf-blind people to everyday facilities and will produce a ready-made market for those trained and researching in those technologies.

From the reviews:

"Once in a while a book is published which you think should have been written years before. Assistive Technology for the Hearing-impaired, Deaf and Deafblind is such a book. ? Each chapter concludes with a series of specific questions concerning the topics addressed, contains elaborate lists of references ? . references to relevant web-sites are given, which are very valuable. ? authors have succeeded in writing a book which is likely to become the standard textbook for students in the field of AT ? ."
