Description

[0001] The invention relates to means for reducing unpleasant sensations from disturbing sounds, sound masking and soundproofing of rooms.

[0002] Devices for reducing unpleasant sensations from disturbing sounds, sound masking and soundproofing of rooms were not found.

[0003] The technical result of using the proposed device is to create a device for reducing the unpleasant sensations experienced by the user from disturbing sounds, for example, noise during repair work in the house or loud music coming from a neighboring apartment or room, as well as sound masking and soundproofing of rooms.

[0004] The specified technical result is achieved in that the device for reducing unpleasant sensations from disturbing sound, sound masking and soundproofing of rooms contains a series-connected sound signal generator that levels (weakens) the uncomfortable sensations from disturbing sound, and N emitters built into one or more soundproofing building structures, N is a natural number.

[0005] An additional technical result consists in the creation of a stereophonic effect that occurs when using two or more emitters built into sound-insulating building structures located at different points in space, which helps to reduce the discomfort from disturbing sound.

[0006] Walls, floors, ceilings, partitions, ceilings, panels, and cladding of the listed structures can be used as soundproofing building structures for embedding emitters into them.

[0007] The audio signal generator can be designed in a form that generates (or reproduces a recorded) signal at an audio carrier frequency, modulated by an envelope of arbitrary shape, in particular, a sequence of pulses of arbitrary shape with the ability to regulate the repetition frequency and / or duty cycle of the pulses, as well as the output signal level.

[0008] A sound signal generator that neutralizes (reduces) the discomfort caused by an interfering sound can be implemented in the form of a sound carrier frequency, modulated by a recorded soothing sound signal, such as one that is close to the sound of rain, or the rustling of leaves, or the sound of the surf, or the sound of pouring sand, or the babbling of a stream, or the chirping of cicadas or crickets, or the singing of birds, or the crackling of burning wood, or various combinations thereof, or a piece of music that is pleasant to the user.

[0009] In each of these embodiments of the sound signal generator, the user's attention will be distracted from the interfering signal by the perception of a soothing or simply pleasant sound.

[0010] At the same time, superimposing the signal from the sound generator on the interfering sound will mask this sound, and soundproofing building structures in which the emitters are built will provide soundproofing of the room.

[0011] The sound signal generator can be started manually by the user or automatically – using a series-connected sound receiver and threshold unit, the output of which is connected to the start input of the sound signal generator.

[0012] The threshold unit can be configured to adjust the threshold level.

[0013] The sound receiver and threshold unit can be built into the soundproof panel.

[0014] When placing the threshold unit sound receiver and the sound signal generator outside the soundproofing panel, the output of the sound signal generator can be connected to the input of the emitter directly or through a wireless communication line consisting of a transmitter, the input of which is connected to the output of the generator, and a receiver built into the soundproofing panel, the output of which is connected to the input of the emitter.

[0015] To generate a sound that eliminates discomfort or disturbing or unpleasant sounds, N additional sound signal generators can be used, which is achieved by introducing a multi-position switch, the input of which is connected to the output of the threshold block, an OR element, the output of which is connected to the input of the transmitter, connecting the start inputs of the sound signal generator and the additional sound signal generators to the corresponding contacts of the multi-position switch, and their outputs to the corresponding inputs of the OR element, N is a natural number.

[0016] Fig. 1 shows a functional electrical circuit diagram of a possible implementation of the proposed device for reducing unpleasant sensations from disturbing sound, sound masking and soundproofing of rooms.

[0017] A device for reducing unpleasant sensations from disturbing sound, sound masking and soundproofing of rooms comprises a sound receiver 1, a threshold unit 2, a multi-position switch 3, a generator 4, a first additional generator 4.1, a second additional generator 4.2, an OR element 5, a transmitter 6, as well as a receiver 7 and emitters 8.1, 8.2 built into a soundproofing building structure 9.1, and an emitter 8.3 built into a soundproofing building structure 9.2.

[0018] The device operates as follows.

[0019] In standby mode (with the power supply voltage of the device constantly applied), when an interfering sound appears, it is sent to the sound receiver 1 and from its output to the threshold unit 2. If the threshold level is exceeded, the signal from the output of the threshold unit 2 starts (depending on the position of the multi-position switch 3) the generator 4, the additional generator 4.1 or the second additional generator 4.2, as a result of which the signal from the output of the selected generator through the OR element 5 is sent via a wireless communication line consisting of the transmitter 6 and the receiver 7, to the emitters 8.1, 8.2 and directly to the emitter 8.3.

[0020] The sound signal from the 8.1, 8.2, 8.3 emitters, superimposed on the interfering sound, neutralizes its impact on the user's hearing, reducing the discomfort experienced in the presence of interfering or unpleasant sound.

[0021] The user can select a specific sound signal according to his / her preference by manually changing the position of the multi-position switch 3.

[0022] The user can adjust the repetition rate and pulse duty cycle, as well as the threshold level at which the leveling signal begins to be emitted, based on their individual feelings.

[0023] In its simplest form, the device may contain only a series-connected generator 4 and emitter 8.3. In this case, when an interfering sound is detected, the user independently activates generator 4 (for example, by supplying power to it).
