Acoustic gun directional action with your own hands. Ultrasonic gun do it yourself

Personal Area

It has always been believed that my house is my fortress. However, moments appear when it is simply impossible in his own apartment.

Delivered the inconvenience can a lot: noisy repairs in the next apartment, very loud music and, of course, drunk makeup from above every night for a long period of time.

The noise that goes on the round day makes it right away to seek at least some decision to eliminate it. However, not everyone knows how to overcome the noisy neighbors.

The federal law states that noise level should not exceed 40 dB in the period from seven in the morning to eleven in the evening, but at night this figure should not go beyond 30 dB.

If you take at least some comparison, then all the sounds should be three times quieter of automotive alarm. But still do not forget that in each region there may be amendments to this law.

If the norms are violated by users of residential premises, all actions from unscrupulous neighbors are transferred to the discharge of an administrative violation.

However, it happens that while there are laws, unfortunately, they are not fulfilled. In this case, there are a pair of options for solving the problem.

When the interference is very loud music, you can try to negotiate peacefully. This method is undoubtedly considered the best at that time if all participants in this conflict are in adequate condition.

It can be explained that you have a child of small age in your apartment and in the afternoon he needed to relax, but in the evening he should go to sleep at nine. You can make a compromise and understand each other.

In the event that the peace negotiations did not benefit, it is possible to go to the district site, which should be sought in this situation at the request of the applicant. If a drunken debacio takes place in a neighboring apartment, then it is best not to climb into it, since it is possible to suffer. In this case, the law enforcement authorities should intervene, which immediately come to the place of call and eliminate the conflict.

Neighbors make repairs

All repairs are a separate topic. Conducting work using a drill, a person honestly thinks that he doesn't do anything bad, as the time working, and therefore the law is not disturbed.

But in some cases, this kind of noise can be worried and the old woman, which was played by migraine and wake up a small child. In this case, it is impossible to complain, since the law is not really broken.

If a person is brought up, then you can independently solve the time of the time of the time of noisy repair work, which will allow for this period of time to go with a child to walk or go to bed at this time, and simply transfer it.

Request for help

So what should be done if the noise continues, and nothing happens to agree? It should be noted that the arrival of the precinct often simply does not give those results that I would like. Very often, the present moment depends on how much corruption is flourishes in this area and, of course, from the personality of the intruder.

In the event that the precinct does not take any measures on the application or does not change anything after it arrives, it is necessary to contact the prosecutor's office, which follows how the laws are observed. There must definitely deal with and the answer will come in writing.

If it did not help here, then only the court remains. If the statement of claim is submitted, there must be weighty evidence that you really can not rest in your apartment because of noisy neighbors.

How will the request affect the ZHES?

There is another instance in which you can turn with a complaint about especially noisy neighbors from above, which I want to pump. There should be referred if there really do not happen any illegal actions that are the debaches.

For example, constantly somewhere dogs dog or just loud music from a neighbor from above. In these cases, it is permissible to appeal to the HCP. As a rule, employees of such a institution say that it is possible to spend some conversation, but it is not a fact that they will open an apartment. Therefore, it is easier to call the police.

However, police officers are in no hurry to help, since their position of the departure is tuned only on illegal actions, and loud music is the work of the Jes. And when the circle is closed, you should think about alternative methods.

There are exceptions

The law on silence has items that may not be distributed over time.

Do not include such items as:

Crying a little sick child;
Meow cat or dog barks;
Call in the bell churches;
Carrying out events and holidays on the street;
Rescue or emergency work accompanied by noise.

Consequences for violators

After the first warning was presented, and the effect was not followed, then an administrative penalty is provided. Its value will depend only directly from the one who served as a concern for anxiety is an individual or legal.

In addition, it is said that they can be brought to pay a fine and those who like to put an amplifier to the balcony. In the law there are clear criteria for the violation of the silence, for which the penalty will have to pay:

Work construction and repair at night;
The use of pyrotechnics and fireworks;
Listening to loud music when applying amplifiers;
Whistle, loud cries and more.

Independent help

In the event that no methods no longer help fight noisy neighbors, you can simply make a repair by applying materials having increased soundproof properties.

However, it is not always a way out. Yes, and the case is quite troublesome. You can try to apply infrasound.

What is infrasound?

Infrasound is customary to call elastic waves, which are analogues of sound, but possessing lower frequencies that people do not hear. The upper limit of the infrasound range is 16-25 Hz.

Until now, the lower boundary is not revealed. In fact, infrase is present in everything: in the atmosphere and forests and even in water.

Actions infrasound

Infrasound actions occur due to resonance, which is the frequency of fluctuations in a large number of processes in the body. Alpha, Beta and Delta Rhythms of the brain also occur on the purity of infrasound, as, in principle, the heartbeat.

Infrasound fluctuations may coincide with fluctuations in the body. Subsequently, the latter are enhanced, due to which the work fails of a body. It can reach not only before injury, but also before the gap.

The frequency of oscillations in the human body varies from 8 to 15 hertz. At the time when the person is affected by sound radiation, all physical oscillations can get into the resonance, but the amplitude of the microsuit will increase many times.

Naturally, the feeling of what affects, a person will not be able to understand, because the sound is not heard. However, there is some kind of anxiety. If there is an extremely long and active impact of a special sound to the entire human body, the breaks of the internal vessels occur, as well as the capillaries.

Typhoon, earthquake and volcanic eruption emit a frequency of 7-13 Hertz, which gives a call to a person to quickly relate from the place where disasters occur. Infrase and ultrasound can very easily bring a person to suicide.

A very dangerous interval of sound is the frequency of 6-9 Hertz. Very strong psychotronic effects most of all are at a frequency of 7 hertz, which is similar to natural brain fluctuations.

At such a moment, any mental work is simply impossible, since there is a feeling that the head at any time can "burst as watermelon." If it is not a strong impact, then it simply rings into the ears and a feeling of nausea appears, vision and the person is worse and the person gives care of a valid fear.

The sound that has an average intensity may upset digestive organs, the brain, to generate paralysis of blindness and general weakness. Strong impact damages or fully leads to a heart stop.

Ultrasonic emitter

You can independently build an infrasound emitter that will not bring any harm to the human body, but the unwanted neighborhood will become less noisy after its use.

Ultrasound design

The scheme is as follows: the simplest generator to create oscillations starts from the coil, which is available in the dynamics for sound. The relay is necessary to start the condenser. If you push the speaker to serve and turn off at all.

Next, the scheme begins to work on the resonant frequency of the coil. We also need transistors that will be low-frequency and produce a specific sound power. As a nutrition, a ninety-toned bearet from a non-working modem is used.

Resistors R2 and R4 are volume controls. The scheme produces work on the pendulum resonance. However, the entire electrician takes about two watts, but at the exit about twenty, so the speaker does not work without them.

Any sound speaker of the LF is suitable. The prerequisite is to put in the housing, since in this case an acoustic "short circuit" is excluded. In the form of the case perfectly fits the pan. At the dynamics for sound, when using the electorole bison, the ears are cut down, then it sticks out in the bucket and grows the "moment" over the perimeter.

Setting up an infrasound device

Initially, the entire system is collected on the table and the entire electrician is checked. Initially, this must be done without a weighting agent. After switching on, the speaker should begin to buzz at the resonance frequency.

If it does not immediately come out, it is necessary to work with the capacitance of the capacitor. Then the entire device is going to the pan, they are sampled with "moment" all the slots between the speaker and the body, and then melt the spiral of the weightlifier and glue the dynamics to the diffuser to the diffuser.

If there is no possibility to find a normal chiser, you should adjust the ultrasound frequency of 13 Hz when using an oscilloscope and a LISU-LISU generator. Then the power is turned on to check for a few seconds to see what happened. Next, the device turns off and the cutting of the spiral of the weighting agent begins until it turns out the double listing.

A certain sound frequency can do the beautiful, creating inconceivable beauty or in a moment to compare the whole city with the Earth, cruelly - but the truth. All the above depends only on the power of the installation itself and select frequency, resonant frequency. But today we will consider not ultrasound weapons of mass lesion, but simply make a small one, but a fairly powerful ultra sound gun, to scare the drunken part of the population. The frequency of the device can be configured in a fairly wide range - from audible to ultrasound. The impact on the body is not deadly, but I want to notice that the feeling is not from the most pleasant, and I do not advise you for a long time next to the emitter.
The scheme is built on a standard logic chip. The generator can be collected on the domestic microcircuit. K561LN2. or import CD4049. - The choice is huge.

These are chips with 6 logical inverters, although the generator itself is assembled on two logical elements. The operating frequency is set by the selection of variable resistor and condenser denominations. The signal from the chip is supplied to the power amplifier, the latter is built on three transistors. The last transistor is power, connected to the head itself.

The device feeds in a fairly wide range of supply voltages, starts starts from 5 volts and clearly runs from 12 volts, the optimal supply voltage is 9 volts, it is very convenient to use the "Crown" type batteries or "Corundum" with a voltage of 9 volts.

In Japan, experienced ultrasound to scare up adolescents

An experiment to scare the juvenile hooligans with the help of a device publishing an extremely unpleasant sound, which can only hear teenagers, was held on Thursday in the Park of the Tokyo district of Adati. According to RIA "Novosti" with reference to Japanese media, residents of houses adjacent to the park have long complained about the noise and the hooligan behavior of adolescents who chose the park for nightness.

These complaints, as well as continuous damage from vandalism in the toilets, forced the administration of the district to conduct a scientific experiment.

Experience has shown that people from 30 to 50 years cannot distinguish high-frequency sound, which reminds them of noise in the train car. At the same time, schoolchildren clap their ears and tried to retire as soon as possible from the sound source.

"A terribly unpleasant sound. As if someone scratches the school board," the 15-year-old schoolboy shared the feelings.

"The sound is impossible to endure for a long time," the 12-year-old schoolgirl ends him.

Three years ago, "sound, not heard for adults" became available for downloading Japan's cell phones. According to one of the companies selling the sound to users of cell phones, only in one year it was loaded for mobiles more than 110 thousand times.

For the protection of public order, the apparatus using the "anti-type" sound is used in Japan for the first time. In the UK, we recall the local developers of a unique source of disturbing ultrasound interference last year began to produce a second model of a similar device - called Mosquito GSM. The first model appeared there a year earlier.

Not only police divisions are becoming customer buyers, but also representatives of transport companies, shops, banks and municipal authorities. All of them are interested in leaving socially dangerous youth from the places of cluster of people and important objects of urban infrastructure.

There is such a device about a thousand dollars and has a radius of action from 15 to 20 meters. No danger of these innovations do not represent, notes the company COMPOUND Security Systems (CSS), based in the city of Gorrty Tidvil in Wales.

It is enough to start using Mosquito, as the profit of the trading point will certainly increase, and theft will decrease, approves the commercial director CSS Simon Morris. In one of the firms, he was told that thanks to the new development, they arrived only in the first week increased by 6 thousand dollars.

One of the new devices is used by the Mark & \u200b\u200bSpencer shop. Railway companies Arriva Trains, Northern Rail and Chiltern Railways also spent on Mosquito, along with several police departments, including London.

Distributors of new products from JNE Marketing say that representative offices have already opened for consulting on the use of Mosquito throughout the country.

Dear Admin, I tried to drag the diaphragm of the LF Dynamics, however, not in your scheme, but simply by connecting it to the Uncle's exit, the speaker scrolls, creaks, a bunch of harmonics and distortion, but from it does not work. Perhaps you need to use any special speakers or piezocrystalline emitters, if it is, what brand are tell me.
And yet, it is impossible to the scheme in the scheme instead of a relay, as a sound source to embed the microphone? The fact is that with the relay it is a one-time action, and having embarrassed the microphone to be suggested to the subconscious and not to rise 2-3 times per night, do not put the device in the window in case of bad weather, rain and snow, and you do not return to our courtyard And transfer to all familiar bruises so that they do not go here.
Vlad.

The lower the frequency of the sound, the more internal volume is needed for the housing in which the speaker is installed.
Diffuse sizes should also be small. In his youth, the Soviet Union produced columns 100-AC-001.
There, on "Nizam" there were speakers with a metallic diffuser, loops with a diameter of more than 50 cm. From them, the infrasound could be obtained. Infrasure will not focus, it spreads in all directions. Remember the subwoofer from the home theater system, where in the room do not put everywhere tambourite. There is a section in physics, the acoustics are called, I recommend to read.

Infrasure will not focus, it spreads in all directions.

It is not necessary to focus, it is enough to create it at a certain point. For example, two intersecting ultrasound rays. They are focused. Apply two ultrasonic phasing lattices, the radiation of which differs from the frequency of the required infrasound. Direct them at an acute angle, in some point of intersection. At the intersection point, due to the interference, we obtain infrasounds. The method, quite often, occurs on the network, and not only for ultrasound.

Alcasha repeller (carefully infraser!)

I have a playground under the window in the courtyard. In the afternoon, the kids are in the sandbox, and in the evenings the playground occupied the alcohonauts-youngsters. Until late Night, they drink, yell, worn - people hinder people. Tired, I decided to disperse, "the author writes.
At home on the mezzanine, two old self-deficient speakers were lying around. He took out of one low-frequency speaker, found a scheme in the old hugs, which set up phase inverters in the columns, the simplest infrasonic emitter configured to the "frequency of fear" in the housing of the plastic vendor.
In the evening, posted a design outside the window and turned on the power. Five minutes later, Alkashne like a cow tongue licked.
Now how the noise rises - I turn on the Pugach for a couple of minutes. In the courtyard - quiet, smooth and God's grace. And since the entire design is the root, then she "blows" only into the courtyard, and not to the house. I even don't even live a dog.
Operating principle. The scheme is an auto-oscillator operating at the frequency of its own resonance of the loudspeaker suspended system. Since the resonant frequency of the dynamics is 40-100 Hz, then it is necessary to reduce it, you just need to drain the suspension system. To do this, in the center of the diffuser it is necessary to glue a spiral from a solder weighing about 20 to 40 grams, then the resonant frequency is reduced to 6-15 Hz. It all depends on the speaker brand, look at the internet.
Design. The concept is the simplest self-oscillator generator that runs from the coil of the speaker, I collected it in the fifth grade when the column was mastered. Relay RES 9 per 5V, slowdown on the condenser C1. In fact, this relay is needed to "push" the speaker and disconnect, then the scheme works on the resonance of the coil of the speaker. Transistors - any low-frequency average power, necessarily on radiators (I took two donke from aluminum jackets from under the cola). Nutrition - 9V Badnik from the killed modem. Resistors R1, R4 - Volume Controller - The scheme works on the pendulum resonance, and although the electrician consumes the order of two watts, at least twenty, and the speaker is shifted without them. Speaker - In principle, any LC, I have an ancient 10 GD-34 to 10 W, with a coil on 4 Ohm, the resonant frequency of the suspension 80Hz. It is necessary to put in the housing to eliminate the acoustic "short circuit". Case - baby plastic bucket. The dynamics of the electric lobby saw the ears, stuck in the bucket and the "moment" was punctured around the perimeter.
Setup - Caution Infrasukhuk !!! First, you need to assemble the system on the table and check the electrician, at first without a weighting agent, when you turn on the power, the speaker must come up at the resonance frequency. I earned with Paul Pink. If it does not come out - go with the capacitor capacity. Then collect the device in the bucket, stipulate the "moment" of the slot between the speaker and the bucket, and the spiral of the weighting agent, mark the "moment" and at the "moment" and stick to the diffuser of the dynamics. Since I could not find a normal frequency meter, then the "frequency of fear" 13 Hz was set up by the oscilloscope and the LISUJE Figure Generator. For this, one input of the oscilloscope filed 26 Hz from the generator, and the other - the wires from the speaker, then, so as not to get under the infrasound, covered the bucket, turned on five seconds meals and looked. Then turned off the power and started to cut the spiral of the weighting agent, until he got a double listing. That's all. I do not post a photo - bucket and there is a bucket.
