How wonderful that we are surrounded by the sounds and we can hear the laughter of the child and the favorite melody!But there is a downside - other sounds that penetrate into the house without asking and interfering relax, work, enjoy life.Psychologists have proved that the noise adversely affects the nervous and cardiovascular system.Therefore, a person simply need "sessions of silence."But how to create a calm, if the window hour drive cars, and for the wall of the neighbor is a fan of your favorite football team?We'll have to figure out how to get the sound in the house and build a barrier on their way.Moreover, sometimes it does not even require special physical costs and the price insulation is acceptable.

property of sound waves to overcome obstacles
When exposed to a solid body, in the air there is a sound wave, which is meeting on the way solid objects is reflected, it passes through them, and partly lost inside.The sound from the source and reflected from the objects form a sound field that acts on the walling.The result is a swing structure, and she becomes the source of the sound passing to an adjacent room sound energy.
The amount of sound energy passing through the structure, depends on the frequency of a sound wave and the characteristics of the material.
sound wave for that would destabilize the structure and go through it, need energy.And the greater the density of the material, the more energy required sound and correspondingly smaller molecules will break through the dense barrier.Thus, materials with high density have the property to reflect sonic energy.They call such materials soundproof.
through tough materials sound gets faster.For example, consider the normal concrete and foam analog.Concrete pretty strong and tough material, but the strength factor foam from below, as it has a porous structure.But thanks to the pores in foam insulation coefficient higher than that of concrete.
What is the frequency
In order to understand whether the design of noise protection, it is necessary to know the frequency of the sound.Quiet sounds are low frequency, it means that the change in low and high sound pressure is slower.Due to this low frequency sounds easier to "shake" design.Save from such sounds can only massive structure with a high density.But in some cases, even a two-meter wall thickness will not be an obstacle.
How dangerous resonance
If the frequency of exposure to the construction of a sound wave coincides with the natural frequency of the structure, they will be included in the response.In this case, the material is not only resistant to vibrations but rather increases the amplitude of oscillation.
In this situation, get help from the sound-absorbing material.They tend to pass inward and absorb sound energy.The soundproof structures they are used to eliminate resonance.By themselves, they are ineffective because they do not able to resist the sound of a low frequency.
So, soundproofing homes can only be effective when properly planned use of soundproofing and sound-absorbing materials.
Nature Origin noise
In order to be protected from noise, it is necessary to know the nature of its origin.
This type of sounds are those that are transmitted through the air, and is a source of conversation, TV, radio.This sound propagates through the standard scenario (using vibrational impacts on the design).For protection against airborne noise is sufficient to fulfill the sound insulation of walls , of whom are neighbors.
In this case, the source of the transmission of noise is the construction itself, which worked mechanically.In this case the inevitable sound transmission to neighboring structures.The sound that easily goes from floors to walls, and vice versa is called indirect.
How much sound is distributed around the house, depending on the materials used.Noise is easily transferred from the heavy materials to the lungs, but the way back it is more difficult to overcome.Therefore, in a house with wooden beams and brick or concrete walls, steps from top neighbors hardly be heard.If the house is built of a material with the same density, the sound wave spreads easily on several floors down.In these homes that would be effective soundproofing, soundproof need all design.
Getting Started soundproof houses or apartments
Before insulation the house, you need to release the walls, floor and ceiling of the building materials and inspect them for cracks.Sound propagation, always looking for the path of least resistance.Therefore, be sure to seal the cracks and expansion joints.Particularly noteworthy outlet.Not isolated outlet is able to increase the penetration of noise at 20 dB.Just do not leave without attention to the holes in the ceiling and walls, through which the pipe.
After all the holes and slits destroyed, sit in a room and listen, from the most penetrating sound.If the problem is too talkative neighbor behind the wall, we proceed to the insulation wall.But before we rejoice that everything was so simple, check whether the sound is transmitted from the problem to the wall adjacent structures.If there is a problem - you need a soundproof ceiling, walls and floor.
Well, in the case where the source of concern is a flat top, will help only a comprehensive approach to solving problems.
Holding soundproofing homes, better to start from the floor.Ideally, the floor top neighbor.But as a rule, this idea is not feasible, and soundproofing floor in his apartment a thing necessary.Do not be heard indirectly transmitted through the floor sound, and neighbors from above will not tell me that you have a herd of elephants was got.
Soundproofing floor is achieved by the device "floating floor".This design consists of a layer of sound-insulating or sound-absorbing material, waterproof, reinforced screed.The main condition - the screed must not be adjacent to the walls, or the sound will continue to be transferred from the walls to the floor and back.In order that it would not happen, sound-insulating material is wrapped up at the height of the baseboard or around the perimeter of the room is sized demfernuyu tape.
Well, what material to choose - insulating or sound-absorbing depends on the type of noise.If the problem lies in the impact noise - sound insulation is needed.With impact noise copes gaskets and soundproof glass fiber mats "Shumanet."For protection against airborne sound using special sound-absorbing materials.It is worth considering that the actual noise-suppressing fiber materials have a thickness of more than 50mm.
In a wooden house can be performed using the same materials.In this case the beams are placed over the soundproof strip.The space between the beams is filled with sound-absorbing material.Logs and floor boards are fixed with soundproof pads that have no hardware has become a source of noise transmission.
easiest way acoustic ceiling suspended unit is considered to be a construction in which as a facing material used plates made of thin mineral or glass fiber.Such designs manufactured by «Ecophon» and "Armstrong".This ceiling can be used in a room with a home theater system.The disadvantage is that these plates can not protect against impact noise.
most commonly used suspension structure, inside which are placed sound-absorbing materials, and the top is closed with plasterboard.This method of soundproofing is effective when fixing the guide will be conducted through the insulating gasket.If the structure is mounted in a room with a home theater system, replace the drywall gypsum fibrous plates.
For best results, stick to the slab termozvukoizol, it is attached flexible membrane teksaund.And only then collected frame.Teksaund also glued to the profile facing a room, and drywall.
materials for sound insulation walls used are the same as for the ceiling fixed on the same principle.To attach the wall soundproofing material with an overlap on the floor and the ceiling.Through the elastic pad fixed frame.It set the sound-absorbing material.In Profile paste soundproof pads and fix plasterboard or gypsum board.
In some cases, you may need soundproofing partitions inside the apartment.It is performed in a similar manner.Well, if you want to build a light barrier, it can not do directly transmitting noise.To do this, going to two separate frame.This is to ensure that between them have not been indirect noise transmission.Between frames leave air space.The interior space is filled with mineral wool.For facing of walls it is recommended to use different materials that reduce the risk of resonance.
sound insulation doors
If the apartment is sealed all the cracks and soundproofed and all designs, but the apartment is still noisy, pay attention to the sound insulation of doors and windows.Very often, the source of the noise becomes ill-fitting door.In this case, the perimeter of the door sealing tape attached.In an extreme case, the door can be dismantled and replaced with a filler in the material impermeable sound.
Soundproofing of windows is to replace the sealing of cracks and sealing gum.But experience shows that most of the noise permeates not through the frame and through the glass.In order to reduce the amount of noise coming through the glass, we recommend double-glazed windows in which the windows will be installed in different thicknesses.In this case, the vibrations occurring at a glass, will not be transferred to another.Since glasses with different thicknesses different resonant frequency.
If you follow these rules in the production of sound insulation work, in your home will always prevail peace and quiet, where you can relax after a busy day that a positive impact on your mental health.
