Summary:
This investigation presents the development of an acoustical model for the study of the reaction of a diving mask on the human vocal tract. The vocal tract and mask cavity are approximated by simplified acoustic elements of uniform geometry within which undamped plane wave motion is assumed. Equations for the impedance at the mouth opening both with and without a theoretical mask cavity are developed from the one-dimensional wave equation. The results are compared with an analysis of the same system using the lumped parameter technique. The impulse response of the mouth opening is found by numerical methods and the extension of the technique to the study of theoretical and actual diving masks is discussed.
