Immittance hearing
WitrynaFor more than 70 years, impedance audiometry has been used in objective diagnostics of hearing, and is presently recognized as one of basic tools for assessment of middle ear disorders. In last decades, especially during last few years, one observes a dynamic development in this field owing to the introduction of new tools and methods. WitrynaImmittance Audiometry. Tympanometry measures the mobility of the tympanic membrane and the middle ear pressure, but it does not measure perceptual hearing. ... Normal hearing is defined as hearing each tone (ranging from 250-4000 Hz) at levels at or below 20 dB. The tones are presented in each ear through air conduction via an …

WitrynaImpedance or immitance audiometry is an objective assessment method of the function of the middle ear. By increasing acoustic pressure in the external ear canal, impedance audiometry measures the sum of resistance which a sound wave encounters on its way through the middle ear to the cochlear receptor. WitrynaTympanometry helps to find and diagnose disorders that may lead to or have already caused a hearing loss. The tympanogram in conjunction with the audiogram helps to …
