Impedance audiometry type c
WitrynaAcoustic immittance refers to either acoustic admittance (the ease with which energy flows through a system) or acoustic impedance (the blockage of energy flow through a system).12 In tympanometry, acoustic immittance measures are used to determine the status of the tympanic membrane and middle ear. WitrynaWhat are the different types of Tympanograms? Tympanogram tracings are classified as type A (normal), type B (flat, clearly abnormal), and type C (indicating a significantly negative pressure in the middle ear, possibly indicative of pathology). ... Impedance audiometry is completely painless and non-invasive, but it requires a small mobility ...
