A study of human head vibrations using time-averaged holography.

Abstract

Intact human cadaver heads were subjected to vibrations. The resonant frequencies over a range of 500 to 3000 Hz were determined. Vibration patterns at three frequencies were presented by means of time-averaged holography. The displacements were quantified and the highest amplitudes were found in the temporal region. Antinode centers were found superimposed on the squamatic suture. This method of holographic interferometry allows sensitive deformation measurements to be taken on intact human heads or skulls.
