Tympanometry and Acoustic Impedance
Acta Oto-Laryngologica, 1977In recordings of the acoustic impedance of the middle ear (tympanometry) the change in air pressure in the ear canal will mostly influence the capacitive component of the acoustic impedance. By choosing a probe tone frequency close to the resonance frequency of the middle ear, characteristic tympanometric patterns can be demonstrated in certain middle ...

In this work we present a new hybrid imaging technique that combines electrical impedance tomography (EIT) with acoustic tomography. The novel technique makes use of the fact that the absorbed electrical energy inside the body raises its temperature, thus leading to expansion effects.
