NettetThe mouth simulator produces a sound-pressure distribution around the opening of the mouth which sim-ulates that of a median adult human mouth, correlating to the figures giv-en in ITU-T Recommendation P.51. The position of the acoustic-centre of the mouth simulator also follows that of human subjects over the speech frequency range. Ear ... NettetThis resulted in a full-range mouth simulator (with an extended response in both the low- and high-frequency range). This not only allows the mouth to be louder it also improved high-frequency roll-off. The new mouth also has a built-in amplifier, simplifying measurement setups and lowering system cost.
