点があった。Conventional Structures and 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. This method has a problem in that it is difficult to quantitatively evaluate blowing and popping sounds because much of it relies on human sensation. Therefore,
As shown in Fig. 1, a low frequency signal from a low frequency oscillator 1 is amplified by an amplifier 2, which drives a speaker 3 and narrows the outlet 3a of the speaker 3 to create a low frequency wind and produce a blowing sound. Or, as shown in FIG. 2, blowing noise was generated by passing wind from an electric fan 4 through a hollow pipe 5. However, it is far from the blowing sound made by a human being with the above-mentioned sound generator, and it is difficult to make the popping sound produced by a small person, so it is difficult to determine whether it is a microphone blowing sound or a popping sound. The drawback was that the evaluation itself was too arbitrary.

有する。Structure of the Invention The uninvented sound generating device generates air from a pressure cylinder, -
- It is configured so that the pressure of the flow is reduced by a pressure reduction regulator, and the flow is emitted from the dummy head [1] through an acoustic element. With this configuration, the airflow from the pressure cylinder can be adjusted using the pressure reduction regulator so that it is equal to the blowing sound pressure generated by a human, so it is possible to reproduce a blowing sound that approximates the blowing sound generated by a human. It has the advantage of being able to be generated stably and efficiently.

It is guided to the solenoid valve 14 through a thin tube as an acoustic element 13.
The airflow passing through this solenoid valve 14 is released from the mouth of the dummy head 16.

ることによりポツプ音を発生させることができる。Here, the air pressure from the pressure cylinder 11 is controlled by a pressure reducing regulator 12.
The pressure is adjusted in the range of 0.5 to 3.0 kg/cA at V
l. By emitting a constant airflow from the mouth of the dummy head 16 through the acoustic element 13 and the electromagnetic valve 14, it is possible to generate a constant flow of wind noise. - The electromagnetic valve 14 is opened and closed at predetermined intervals by a gating device 15, and a pop sound can be generated by controlling the time for generating a constant flow rate.

正しく判定し評価することができる利点を有する。As described in detail above, the effect of the invention is that the airflow from the pressure cylinder is depressurized by the pressure reducing regulator and then released from the mouth of the dummy head through the acoustic element, so that it is difficult for a human to blow the air. It has the advantage of being able to generate a blowing sound close to the sound,
This has the advantage that the chancel effect on the sound of the microphone can be correctly determined and evaluated.
