Abstract

PURPOSE:To prevent an emotion unstable phenomenon and to secure a comfortable living space by radiating an ultrasonic sound to the internal part of a closing construction. CONSTITUTION:A microphone 3 is located outside a closing construction 1 and gathers an external acoustic sound. A filter 4 is a high-pass filter or band- pass filter to pass only the signal of an ultrasonic band and to interrupt the others among sound signals gathered by the microphone 3. An interrupting frequency is made into the degree of 10KHz, and in the case of the band-pass filter, it is made into the degree of 10-30KHz. The signal to pass the filter is amplified by an amplifier 5 and radiated in a room by a loudspeaker 6. An external surrounding noise is dummily generated. The output of a signal generator 7 can be radiated from the loudspeaker 6 by being amplified by the amplifier 5. The signal generator 7 generates a white noise by using, for example, a shift register. Through an electric equalizing circuit, a correction to a pink noise can be easily executed. A reproduction may be executed by gathering ultrasonic noises into a memory beforehand.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is an environment improvement device for preventing emotional instability in a closed structure environment such as a concrete house and ensuring a comfortable living space.

[Conventional technology]

Conventionally, the rock effect has not been known at all for environmental sounds in the frequency range above the allowable range, and therefore, no device similar to the present invention has existed at all.

Recent research has revealed that the lack of noise in the ultrasonic range in the living environment causes significant emotional instability (Showa 6).
Asahi Shimbun, February 21, 2013).

[Means for solving problems]

FIG. 1 shows an example of the application of this device. The living environment is improved by emitting ultrasonic sound from a speaker 6 into the interior 2 of a sealed structure 1 which is acoustically sealed from the outside, such as a concrete house.

[Function and Examples]

The microphone 3 is mounted outside the sealed structure 1 and collects external sound.The filter 4 is a bypass filter or bandpass filter that passes only the ultrasonic range of the sound signals collected by the microphone 3 and blocks the others. It's a filter.

The cutoff frequency is approximately 10 KHz (in the case of a bandpass filter, it is approximately 10 KHz to 30 KHz).

The signal that has passed through the filter is amplified by an amplifier 5 and radiated into the room by a speaker 6.

2 and 3 are alternative embodiments of the invention. In the figure, the sealed structure is omitted.

It is known that an electric circuit can generate pseudo ambient noise, and this can be used to generate ultrasonic sound from a speaker. It is emitted from the amplified speaker 6.

The signal generator 7 can generate white noise by using, for example, a shift register.

(For example, published by Radio Gijutsusha on June 1, 1978, CMOS
(Digital Circuit Manual, by Yokoi, p. 117) White noise can also be easily obtained by using the terminal noise of a Zener diode and amplifying the alternating current.

Furthermore, it is easy to modify these random noises (white noises) into pink noises (1/f noises) by passing them through an electrical equalization circuit. This equalization circuit is -3
It has a slope of dB10ct and is well known, so it will be omitted.

FIG. 3 shows yet another embodiment.

Ultrasonic noise in a comfortable environment is collected in memory 10 using microphone 3 in advance. Recorder 9 is a device that records the signal from microphone 3 in memory 10 .

The memory 10 is a magnetic recording optical recording or binary RAM.
Alternatively, a semiconductor memory such as ROM recording can be used. The recorded memory 10' is inserted into the regenerator 8, and the signal is reproduced and radiated to the amplifier 5 from the loudspeaker 6.

〔Effect of the invention〕

The ultrasonic noise emission of the present invention improves the habitability of closed spaces and improves mental stability or emotional stability.
