¿µ¹®³»¿ë¿ä¾à The standard describes the artificial mouth telephonometric use. The methods of use of the artificial mouth are outside the scope of this standard.
The artificial mouth is a device that approximates the acoustic field generated by the human mouth in the near field. It is used for measuring objectively the sending characteristics of handset-equiped
telephone sets as specified in ITU-T Rec. p. 64. It may also be used for measuring the sending characteristics of loudspeaking telephones at distances up to 0.5m from the lip plane, but the accuracy with which it reproduces field is slightly reduced
