The loss of hearing is one of the common problem that can occur at any stage of human life, and makes verbal communication difficulties. The hearing loss may be caused by a pathology in one or more sections of the human ear. This book concentrates on the study of the dynamics of eardrum membrane by using laser interferometric technique as a hearing diagnostic tool. The experimental and mathematical study of how the changes in membrane homogeny, and it's physical properties can affect its vibration in response to the impact of the sound waves are presented in this book.

The experimental and mathematical study of how the changes in membrane homogeny, and it's physical properties can affect its vibration in response to the impact of the sound waves are presented in this book. A Michelson laser interferometer was used in the practical study part to measure the frequency response of loudspeaker membrane and rabbits eardrums. A mathematical model for circular drum membrane vibration was used also to simulate the eardrum membrane vibrations.
