Influence of Piriform Sinuses and Valeculae on the Resonance and Antiresonance Characteristics of the Human vocal Tract - Numerical Simulations
Original language description
The influence of the vocal tract on vocal output has been studied rather extensively, the influence of side cavities of human vocal tract, such as the piriform sinuses (PS) and valleculae (VA) has received much less attention. Generally, these cavities have been reported to cause antiresonances in the resulting vocal spectrum, i.e., largely decreasing the radiation of some frequencies out of the mouth, particularly around 4-5 kHz. As such, their role for the resulting vocal intensity may be considered undesirable, since it contrasts with the general goal of achieving maximum vocal output with the smallest vocal effort. However, a more detailed analysis reveals that besides the antiformants there are also new formants which occur due to these side cavities. In technical terms, the effect is side cavities can be described as creating a zero-pole pair in the overall transfer function of the vocal tract. The contribution investigates the influence of PS and VA and their size on the resonan
