Abstract

The knowledge of the particular role in sound formation of the different parts of the human vocal organ and of other parts of the body are of interest for medical applications as well as for prediction of the vocal timbre of students studying voice. Investigations on the human vocal organ are complicated by the fact, that there is no direct optical access with the naked eye to this organ and that its functioning is influenced by any contact with an optical instrument. Assuming that the air vibrations in particular resonance cavities as well as the vibrations of bones and tissues will be transferred to the nearest skin areas, it can be expected that investigations of vibrations of the skin surface may give some information on internal parts of the body, here especially on the vocal organ. Thus, the problem of a non-contactive analysis of the function of the human vocal organ could be partially reduced to investigations of the skin vibrations of the frontal part of the neck. The double-pulse holographic interference method was used for such investigations, because of many advantages described in [1,2].
