This text provides an introduction to the field of audiology, beginning with the profession itself and foundational concepts in acoustics and sound measurement, including frequency, intensity, time, and auditory sensitivity. It then covers the anatomy and physiology of the auditory system, from the outer ear through the central auditory pathways, and introduces tools and environments used in hearing assessment such as audiometers and audiograms. The manual further explores basic audiological evaluation procedures, including pure-tone testing, classification of hearing loss, hearing screening, speech audiometry, and acoustic immittance testing. It concludes with an overview of common auditory disorders, including vestibular and hearing-related conditions, supported by supplemental materials and worksheets to reinforce clinical understanding and applied practice.
