On-going hearing research efforts are focused on the tympanic membrane (TM) and its role in transforming the energy of the sound waves from the outer-ear into mechanical vibrations of the middle-ear bones. Quantification of acoustically-induced nanometer scale motions of the TM is important for the understanding of the human hearing process. Several research groups have been studying these displacements resulted from tone stimuli [1, 2]. However, transient response of the TM, e.g., the behaviour of the eardrum excited by a short pulse (as opposed to tone) needs further investigations.
