まいなものになつてしまうという欠点があつた。Configuration of conventional example and its problems Generally, in order to determine the presence or absence of a blowing sound or popping sound in a microphone, a person generates a blowing sound or a popping sound and performs the evaluation. This method has a problem in that it is difficult to quantitatively evaluate blowing and popping sounds because it relies heavily on human sensation. Therefore, as shown in Fig. 1, the low frequency signal from the low frequency oscillator 1 is amplified by the amplifier 2, and the speaker 3 is driven and the outlet 3a of the speaker 3 is narrowed to create a low frequency wind. As shown in FIG. 2, wind from an electric fan 4 is passed through a hollow pipe 5 to generate a blowing sound. However, the above-mentioned sound generators are far from the blowing sounds produced by humans, and it is difficult to produce the popping sounds produced by humans, so it is difficult to judge whether they are microphone blowing sounds or popping sounds. The drawback was that it itself became vague.

定して発生させることができる利点を有する。Structure of the Invention The sound generating device of the present invention is configured such that airflow from a pressure cylinder is reduced in pressure by a pressure reduction regulator, and is emitted from the mouth of a dummy head through an acoustic element. According to this configuration, the airflow from the pressure cylinder can be adjusted by the pressure reduction regulator so that it is equal to the blowing sound pressure generated by a human, so that a blowing sound similar to the blowing sound generated by a human can be reproduced. It has the advantage of being able to be generated stably and with good quality.

The figure shows one embodiment of the present invention, and in FIG. 3, air pressure from a pressure cylinder 11 is adjusted by a pressure reducing regulator 12, guided through a thin tube as an acoustic element 13 to an electromagnetic valve 14, and Airflow passing through valve 14 is discharged from the mouth of dummy head 16. Here, the air pressure from the pressure cylinder 11 is regulated in the range of 0.5 to 3.0 kg/cm 2 by the pressure reducing regulator 12, and is released from the mouth of the dummy head 16 through the acoustic element 13 and the solenoid valve 14 as a constant air flow. By this, constant flow sound, that is, wind sound can be generated. On the other hand, the solenoid valve 14 is opened and closed at predetermined time intervals by a gating device 15.
A pop sound can be generated by controlling the time during which the constant flow rate is generated.
