Abstract

Time-averaged holography is applied for vibration analysis of the tympanic membrane of frog, guinea-pig and human cadaver. Vibration. characteristics of human stapes which acts as a transmitter of vibration from tympanic membrane to internal ear were studied. Vibration of human skull by means of bone conduction. hearing and bone conduction hearing aid were analysed. Then, bone conduction. mechH.nism of skull with bone conduction hearing aid was investigated. Finally, possibility of holographic recording and holographic interferometry used with optical fiber system was studied theoretically,and it is verified with experiments.
