Abstract: An object of the present invention is to provide a speaker mounting device which does not permit a dismounting work without using a tool but enables an easy dismounting work using the tool. A speaker mounting device 1 of the present invention comprises a speaker component 2 provided at a speaker, and a wall component 3 to be provided at a wall. The speaker component 2 is configured to be slid in a first direction with respect to the wall component to be mounted to the wall component 3. The speaker component 2 is configured to be slid in a second direction with respect to the wall component 3 to be dismounted from the wall component 3. The speaker component 1 includes a movement prevention member 5 and a shaft member 6 coupled to the movement prevention member 5. The shaft member 6 is rotated to cause the movement prevention member 5 to rotate around the shaft member 6 which is a rotational axis. The shaft member 6 has an outer end of a screw head shape or a bolt head shape. The wall component 3 is positioned in the second direction relative to a rotational trajectory of the movement prevention member 5 in a state where the speaker component 2 is mounted to the wall component 3.

Abstract: A howling margin measuring device (20), comprising a treatment means (28) having a gain regulating means (21) and a compressor (22) connected in series to each other and a control means (23). The gain regulating means (21) gives a gain to an inputted voice signal and outputs that signal, and the compressor (22) compresses the voice signal at a specified ratio when the level of the inputted voice signal is equal to or higher than a threshold level and outputs that signal. The control means (23) can control the gain of the gain regulating means (21), and can read the compression level of the compressor (22). The control means (23) reads the compression level of the compressor (22) while gradually increasing the gain of the gain regulating means (21) and, based on whether the read compression level is above a specified value or not, determines whether howling occurs or not. Then, based on the gain of the gain regulating means (21) obtained when the control means (23) determines that howling occurs, the control means (23) calculates howling margin.

Abstract: Resonance frequencies f2, f3 detected in a resonance space are decided to be dip center frequencies. According to the measurement values obtained in a loudspeaker and a microphone in the resonance space, a basic amplitude frequency characteristic Ca and a target amplitude frequency characteristic Cd are obtained. The target amplitude frequency characteristic Cd has a greater smoothness than the basic amplitude frequency characteristic Ca on the frequency axis. The dip attenuation level and sharpness are decided according to the difference between the basic amplitude frequency characteristic Ca and the target amplitude frequency characteristic Cd at the dip center frequencies f2, f3 and in the vicinity thereof.

Abstract: Provided is a soil-volume reduction method capable of significantly reducing the volume of soil in comparison to conventional methods. A soil-volume reduction method includes: rotating agitating blades 3 of a soil improving apparatus 1 to thereby agitate target soil 5 to a prescribed depth in a prescribed range and form a disturbed region 6 in the target soil 5; and then installing drains 7 in the target soil 5 and discharging water W in the target soil 5 out of the target soil 5 through the drains 7 to thereby increase the amount of consolidation of the target soil 5 and thus reduce the volume thereof.
