Abstract

The paper describes preliminary results of the use of double-pulse holographic interferometry for vibration investigations of the skin surface of a singer’s face (epiphysis), neck, larynx, and sternum. Holographic interferograms obtained in the experiment illustrate a dependence of the distribution of vibrations on the type of sound and on the fundamental frequency for the same person. The vibration interferograms of various persons are different even at the same sound and frequency. The method may become useful for diagnosis of voice timbre as well as in pathological cases.
