Paper Abstract

The study of the tympanic membrane is fundamental because it is one of the most important components of the middle ear. By finding the membrane's vibration patterns and quantifying the induced displacement, it is possible to characterize and determine its physiological state. Digital Holographic Interferometry (DHI) has proved to be a promising optical non-invasive and quasi-real time method for the investigation of different mechanical parameters of biological tissues. In this paper, we present a digital holographic interferometry setup used to measure the frequency response of the tympanic membrane in post-mortem cats subject to acoustic stimuli in the range of 485 Hz up to 10 kHz. We show the resonant vibration patterns found for this range of frequencies and the corresponding displacement amplitudes induced by the acoustic waves. The results show the potential that this method has to help improve the understanding of the tympanic membrane's working mechanisms.
