[Subjective and objective audiometry].
Audiometry uses physically precisely defined acoustic stimuli. The response can be either a subjective reaction of the patient such as to press a button, or it can be a physiological reaction that can be measured objectively such as the acoustic reflex of the stapedial muscle. The aims of both types of audiometry, subjective and objective, are the assessment, the localization and the quantification of hearing loss. Specifically selected subjective or objective tests, and combinations of both, are being used to answer different clinical questions related to audiometric screening, audiological diagnosis, and quantitative description of the hearing loss. The selection of tests should be designed to answer the specific question most effectively.
