Abstract:
The gas or oxygen masks deploy elements out of which the speech membrane is important. A few indicators such as cut-off frequencies, distortions and transfer function can be used to characterize the membrane. A difficult issue is the measurement of system task in the membrane transfer. We have investigated these issues in this paper. We have studied the influence of a device coupling on the sound source and tested speech membrane. Further we have studied the position of microphone in reference to the sound source. We have thus applied five different couplers and four microphone distances.
