Pure tone audiometry
It is the key hearing test used to identify hearing threshold levels of an individual, enabling determination of the degree, type and configuration of a hearing loss. Thus, providing the basis for diagnosis and management.
Acoustic immittance measures (tympanometry and acoustic reflex thresholds) provide important information about the presence of a conductive component. Abnormal tympanometric results signify the need for medical assessment, the presence of normal tympanometry does not rule out a conductive component, as normal tympanograms can be recorded in ears with ossicular abnormality.
Speech audiometry has become a fundamental tool in hearing-loss assessment. In conjunction with pure-tone audiometry, it can aid in determining the degree and type of hearing loss. Speech audiometry also provides information regarding discomfort or tolerance to speech stimuli and information on word recognition abilities.and can help determine proper gain and maximum output of hearing aids and other amplifying devices for patients with significant hearing losses and help assess how well they hear in noise. Speech audiometry also facilitates audiological rehabilitation management.
