This is a major revision of the leading text for the introduction to hearing and hearing disorders course required of all SLP/A majors. Known for its in-depth coverage of the physics of sound, anatomy and physiology of the auditory system, causes and treatment of hearing disorders, and the relevant diagnostic and therapeutic techniques, Introduction to Audiology is now augmented by an instructional CD-ROM.The accompanying CD-ROM features visual and auditory demonstrations, samples of audiograms representing different kinds of hearing loss, different sound stimuli, and filtered speech to simulate sensorineural hearing loss. It also includes an extensive literature section with useful forms, addresses of organizations, publishers, lists of books of special interest, and much more.
