Hearing aid audiologists require a firm basis of theory as will as practice in order to become fully registered under the Hearing Aid Act of 1984. This book covers the Hearing Aid Council examination syllabus, introduces aspects of hearing aid audiology, and lays the theoretical foundations and then applies this theory to current practice. Divided into three parts, Part one provides an introduction to the basic sciences which underpin hearing aid audiology. Part two is devoted to the practice of audiology with and emphasis on audiometry, otoscopy, hearing aid selection and evaluation, and rehabilitation. Part three considers the management of specialized problems, including tinnitus and diagnostic audiometry, and introduces paediatric audiometry.
