The comfortable atmosphere of the personal space of a wooden house largely depends on high-quality sound insulation from the next room. Despite the fact that wood is a good conductor of noise, the frame house is quite quiet. This is due to the design features of walls, partitions and ceilings. Let's figure out how to make soundproofing of walls and ceilings in a wooden house so that nothing causes discomfort.
It's good to live away from noisy streets, rushing cars, surrounded by fresh air.
Country idyll - nature, heady air, silence, birds sing. The beauty.
When choosing to build a timber frame house, people often wonder how quiet the house will be. Is the sound insulation of the walls of a frame house really as good as experts say? Consider how the sound insulation of the outer walls of the house, partitions and ceilings is arranged. What is the sound absorption coefficient of a frame wall, given its small thickness?
According to the standards, the sound insulation of the outer walls of the house must be from 50 decibels and above, and the partitions between separate rooms - at least 43 decibels.
In a frame house, the sound insulation of wooden walls in terms of their values is close to 70 decibels, which is typical for a wall made of 2-meter thick bricks.
In practice, these are indicators that minimize noise penetration. This effect is achieved due to the peculiarities of construction technology.
To understand the issue, let's make a short theoretical excursion. .
Noise can be different, the following characteristics of sounds are distinguished:
Well, everything is clear from the name - these are voices, cars. Acoustic noise works on walls and glazed surfaces. And finally,
By its nature, it can be shock or airy.
Therefore, in order to make a quiet house, it is necessary to reduce to the maximum impact, acoustic and structure-borne noise. Let's start with the simplest, acoustic one.
Absolutely soundproof rooms do not exist, noise is typical for city apartments and country houses. If the object is located next to a road or railroad, there will be a high level of airborne noise.
And, nevertheless, even with this arrangement, if high-quality sound insulation of the walls in the house is made, the noise level can be significantly reduced.
The frame structure of the walls is fine protects against acoustics, as it has a three-layer structure. The inner cavity of the frame is filled with a soft fibrous material that has high heat and sound insulation properties.
The most commonly used mineral and ecowool, foam insulation, isover and other dense fillers. Their offer in the construction market is quite large.
On the outside and inside, sheathing is performed with oriented strand board (OSB), cement-bonded particleboard (OSB), moisture-resistant plywood or gypsum plasterboard, depending on preferences. These materials not only provide structural strength, but are also excellent sound absorbers.
Sound insulation of the walls is installed and partitions in a private house, usually during the construction phase. The frame wall is made of wooden racks located at a distance of 0.55 - 0.
6 meters (standard widths of many heat and sound insulating materials). Soundproofing is tightly placed between the posts of the frame house. If necessary, pass along the perimeter of the frame with silicone sealant or foam. The tighter the insulation is laid, the better the sound protection will be.
Wood is a good conductor of sound.
With insufficient noise isolation, even small sounds will resonate throughout the space. To reduce audibility between different zones, it is required to perform soundproofing of interior walls and partitions. Currently, interior frame walls are becoming more and more popular.
The structure of the frame wall: insulating sound-insulating material is placed between the posts, the outer sheathing is performed from plywood, chipboard or OSB.
Internal frames can be sewn up with drywall.
This is a very high quality material in terms of noise reduction.
If you want to make soundproofing of walls in a wooden house with your own hands, it is not difficult at all, choosing the right materials. While it is quite easy to deal with acoustic noise in frame construction, reducing impact noise requires additional efforts.
Frame walls are not very reliable to protect against impact noise. Even tightly installed soft insulation does not interfere with the spread of sounds of this kind, spreading throughout the house and banishing silence.
It is good if the house is located away from a busy highway or railroad. In this case, impact noise does not appear often.
To increase the level of impact sound absorption, polyurethane foam core fillers, synthetic rubber, latex and fibrous materials are used. Main criterion: the higher the elasticity of the material used, the higher the sound insulation properties from impact sounds. It is good to use glass wool, basalt heaters in soundproofing partitions.
They provide sound absorption and increased fire safety.
In the floors of a frame or wooden house wood is used. Beams, floorboards, ceilings, the floor of the second floor, sewn with clapboard, add environmental cleanliness, but at the same time have excellent permeability of sound waves. The hardware used in the installation process (self-tapping screws, beam supports, fixing angles), being metal products, increase the sound transmission of the floors.
Quite often, impact noise (sound of footsteps, even slight movement of furniture, moving a chair) can cause discomfort.
Although a person is such a creature that he can get used to anything, nevertheless, protection against percussion sounds must be equipped when installing floors. It will be problematic and costly to reduce the level of such noise during operation without additional investments.
Imagine this picture: on the top floor, someone dropped a slipper, and you woke up, staring at the ceiling and with an effort remember literary words. Do you like this situation? I doubt it. And all because an important rule of construction has been violated: DO NOT MAKE HOLLOW COVERINGS inside the house, categorically.
Sound insulation of floors is made combined, the material is tightly laid, with full filling of the floor volume.
It must be remembered that sound bridges (contact of wooden elements) are the same disadvantage as cold bridges. Their presence will reduce all efforts to build sound insulation to zero. Materials with a dense structure (fiber, jute mats, tow, mineral and natural wool, expanded polystyrene) have good sound-absorbing properties. But this may not be enough to completely eliminate impact noise.
Floating floor is an excellent option for protection against impact sounds. Insulation is installed so that there is no rigid coupling of structural elements of the house (floors with walls). Damping resonators are arranged along the lags and beams of the structure. The logs lie loosely, not connected to the floor joists. The space between them is tightly filled with soundproofing material.
The sub-floor decking is mounted to the joists. An additional underlay can be laid on the logs to increase efficiency. The noise level is also reduced by the lining under the beams in the places where the pieces of rubber are supported.
To avoid the propagation of sounds, floors and flooring should not be close to the wall. The small gap left is filled with fiberboard, ecowool and similar materials.
Then primed with water-based acrylic paint to completely fill the voids.It is imperative to use a waterproofing film in the interfloor cake, which also effectively absorbs noise.
If the soundproofing of the ceiling is not enough, sometimes it is more economical to soundproof the ceiling.
The least expensive way is to sheathe the ceiling with special panels. The most optimal material for this is expanded polystyrene.
The ceiling is mounted suspended, like floating. The frame structure of the suspended ceiling is filled with sound-absorbing materials, the filing is made with plasterboard. An excellent method of reducing impact noise is to use independent floor and ceiling joists. More powerful beams are installed for the floor and additional, thinner ones - for hanging the ceiling.
The noise of a structural nature affecting the entire structure of a building is more problematic, although possible, to reduce.
For this, it is necessary to remove the rigid connections of the noise-propagating planes with other structural units. This can be done by using plastic elastic seals (pillows) and vibration suspension.
To ensure a good effective silence in the house, you need to pay attention to the sound insulation of communications, heating and ventilation systems.
Wood is a sonorous material, with increased reflection of sounds. The sound insulation characteristics of wood, especially dry wood, are not high.
Therefore, even insignificant quiet sounds can be heard almost anywhere. The presence of a large amount of cladding in the premises of the house increases the spread of sounds. The main sound absorbers in the rooms are the abundance of textiles, carpets, soft corners, ottomans. Such interior solutions make absolutely any living space quieter.
There is a significant list of materials on the market today to reduce exposure to noise.
They are different in thickness (from 20 to 200 mm), shape (roll, plate, mat). The main requirement for sound insulation is high-quality noise absorption with a minimum thickness. Good thin noise insulators are polyethylene, polyurethane, cork. Sound insulation of plasterboard walls for internal partitions in the house will be of high quality, due to its high sound-absorbing characteristics. Economical option - foam and mineral wool.
True, they differ in noticeable thickness, but they also perform the function of thermal protection.
When soundproofing a wall, partitions and ceilings in a wooden house is planned, the material is selected taking into account the thickness of the walls, the architectural features of the building. The nature of the noise, which the owners want to eliminate or minimize, is also taken into account.
