Otoacoustic emissions in practice - standard and special examinations are described in detail: - newborn screening - early detection of hearing impairment - differential dignostics of endo- and retrocochlear lesions - monitoring in noise exposure - ototoxicity - hearing loss - tinnitus - measurement, evaluation and interpretation of otoacoustic emissions. Direct comparison with other audiological procedures and interpretation of data in the context of functional and morphological findings facilitate sound differential diagnosis. - Case studies from practice illustrate typical, but also special OAE applications, point out possible sources of error and provide the necessary intuition for the evaluation and interpretation of data. - The content compilation corresponds to the range of services of the advanced training course.
