Two of the parameters, static admittance and tympanometric width, were measured automatically at a standard 226 Hz frequency.
WebTympanometry is a clinical test measuring tympanic membrane (TM) mobility and is graphically displayed as a tympanogram. Tympanometry provides information on acoustic admittance, which is a measure of the ease with which energy flows through the middle ear system, and impedance, which is the opposition to this flow (Hall and Mueller 1997).The … WebAdmittance is how energy is transmitted through the middle ear. The instrument measures the reflected sound and expresses it as an admittance or compliance, plotting the results on a chart known as a tympanogram . …
