Subjective audiometry tests hearing depending on the subject’s subjective responses to various sound stimuli. Basic aspect of hearing is assessed by pure- tone audiometry, in which pure-tones with selected frequencies are presented at various intensities. Higher auditory function can be tested by speech audiometry, which is important for assessing the degree of communication disorders. These tests usually provide reliable quantitative measures on a subject’s hearing function, if the subject understands the test procedure and is cooperative. However, we have to pay appropriate attention during the test and when evaluating the results in special populations, for example, in young children, since results of audiometry vary depending on the subject’s level of concentration on the test, and the skill of the examiner. In this chapter, basic principles and purposes of pure-tone and speech audiometry are explained to help understanding the outline of subjective audiometry.
