One of the main disadvantages of living in a multi-storey high-rise building can be called with great confidence the almost zero level of sound insulation. Moreover, if the house is an apartment building, then each of the tenants has their own idea of the permissible volume level: some are not averse to starting deafening repairs starting in the morning of the day off, some are not embarrassed by loud music right in the middle of the night. And if these examples are most often episodic, then the sounds of neighbors' steps will be constant companions of living in such a dwelling. However, this problem has a solution in the form of installing a soundproofing system for each specific apartment, with the help of which the owner will not only not interfere with the neighbors, but will also save his family from extraneous sounds. And the leading role in such a system will be played by vibration-isolating suspensions and fasteners (also referred to as vibration suspensions and vibration fasteners).
Content
The main purpose of such suspensions and fasteners is to increase the overall sound insulation performance, that is, to effectively absorb sound vibrations emanating from the inside of the room and not transmit vibrations received from outside into the room. This is especially true for plasterboard ceilings. In the process of installing such a ceiling sheet, the frame is first assembled, and then it is sheathed. At the same time, an air gap appears between the frame and the skin, which is not only an excellent acoustic conductor, but it is also capable of amplifying sound vibrations by several times. As a rule, this issue is solved by simply filling the voids with mineral wool or other sound insulating materials. However, this method does not fully solve the issue, because the frame itself is also capable of transmitting sound vibrations, since it is attached to the ceiling by means of suspensions, which, in turn, are usually made of metal, which makes them an additional excellent sound conductor. This is where vibration-proof fasteners and suspensions come to the rescue.
The whole essence of the secret of the effectiveness of these devices lies in their special design and they consist of:
There are also vibration suspensions, the fastening elements of which are coated with an anode solution - these samples have increased strength indicators.
The vibration isolation fasteners / suspensions that are widely used today are usually capable of withstanding a load of 20-30 kilograms, however, there are also heavy-weight models that can withstand weights of 40 kilograms or more.
Before starting the installation of the ceiling, simple calculations should be made regarding the number of vibration suspensions that will be required for reliable sound insulation. Experts are inclined to use the following ratio: for every 15 square meters, on average, 40 to 50 vibro suspensions are required.
It is worth remembering that vibration isolation fasteners / hangers are the most important element of the ceiling construction in the room. Mankind has not yet invented to extinguish sound vibrations in a different, less expensive way. The simplicity of the design of these devices suggests that it is quite possible to make them yourself. However, in the wrong hands, such an initiative can result in low efficiency of the entire system, coupled with a short overall service life.
Different solutions in engineering will affect the suppression of extraneous sounds in different ways.
Partial soundproofing can be carried out on one or more surfaces. At the same time, it has a point of concentration of efforts, concentrating on a certain direction from which the sound comes. In this case, the sound-absorbing material is laid inside the ceiling frame, which is fixed on vibration suspensions.
IMPORTANT! It must be remembered that different materials will deal with unwanted acoustic waves in different ways: drywall and gypsum fiber sheets (gypsum boards) will absorb sound, while cork, mineral or foam fillers will reflect it.
Complete soundproofing is a comprehensive solution that insulates not only the ceiling, but also the walls and floor. Such arrangement of the premises will allow getting rid of even the indirect transmission of acoustic vibrations. The main disadvantage of this scheme is that it will significantly reduce the volume of useful living space in the room, since frame structures will be installed everywhere. In addition, with complete insulation, the floor will be made in a "floating" format, which means a thickening of the floor covering itself by an average of 50 - 80 millimeters. Naturally, such a coating will completely extinguish the noise from running children or movable furniture, and the sound insulation index will reach the limits of 15 - 18 decibels with an acceptable 10. As practice shows, such a decision will be justified with large areas of the apartment and if the owners have advanced financial capabilities.
The vibrating suspension is a U-shaped profile structure, on the upper crossbar of which a special insert made of elastic material is installed. Typically this material is polyurethane, rubber or regular rubber. It is this soft base that takes on the influence of the sound wave and extinguishes it. The whole process of exposure consists in the fact that the force of the acoustic wave is significantly wasted to compress the elastic gasket, rotate the hinge, and in the future, its forces are simply not enough to act on the protective structure itself. The efficiency of the gasket directly depends on its thickness - the thicker it is, the greater the vibration amplitude it is able to damp. As a rule, the vibration suspension is fixed with an anchor to the wall / ceiling, and the reverse part is attached to the frame by means of self-tapping screws.
The great popularity of these devices among the population is due to the following important advantages:
The modern market of finishing materials is able to provide the buyer with a wide range of these devices. They can differ in the type of fastening, in the place of use, in dimensions, as well as in the materials and dimensions of the insulating washers.
Among professional finishers, it is generally accepted that the best option for the type of fastening is a box-type vibration suspension. Its design is most successfully designed to absorb acoustic waves, almost completely preventing them from penetrating the surface of the ceiling or plasterboard wall. The main disadvantage of this type is that before installation, you will need to set the studs on the profile as accurately and scrupulously as possible. In addition, their cost is far from small.
In terms of their dimensions, vibro suspensions for gypsum plasterboard sheets can be standard, used for mounting on a profile with a width of 6 centimeters, and can be made in economy class for a narrow profile, where their width will be 4.7 centimeters. Absorbent washers are usually made of rubber, polyurethane or rubber. All described devices must withstand a maximum load of up to 30 kilograms. Their adjustment can be carried out by means of holes that are located on the sides of their U-shaped structure.
The simplicity of the design of suspensions / fasteners allows you to make them yourself, despite the fact that the technology is quite simple, and the end result may not be inferior in efficiency to factory samples. For the entire procedure, you only need perforated metal plates and pieces of porous rubber. The required number of suspensions must be calculated in advance, based on the area of the insulated room (approximately 40 pieces per area of 15 squares). For the direct manufacture of vibration fasteners, you need to bend the perforated metal plate to the shape of a rectangle (U-shaped view), and fix a rubber gasket in the center. The final stage will be the usual bending of the edges of the plate. In order to increase efficiency, it is worth installing not one, but several gaskets on each mount - this will increase the quality of sound damping and prevent the further spread of vibrations to the drywall as much as possible.
At the end of the suspension production procedure, it is worth testing them. To do this, the vibro suspension is fixed on a small wooden block, after which they need to hit the floor well. Immediately, after the impact, one should carefully observe the vibrations that the plates produce. The faster the vibrations of the edges of the structure go out, the better the vibration isolation properties and the general ability to damp the vibration of the entire system as a whole will be.
When choosing factory samples of suspensions / fasteners, you should pay attention to their strength. The vibro-suspension has a significant load to maintain the gypsum plasterboard, coupled with the insulating material, and they also need to hold the putty layer. The budget versions of these devices are usually adapted to hold a weight of up to 12 kilograms, the standard ones are already designed for 15 or more. The heavyweight versions are adapted to weigh 40 kilograms for the wall and 30 kilograms for the ceiling. Also, the high-quality functioning of the fasteners will depend on the thickness and area of the elastic washer - the larger it is in volume, the better the insulation will be. The same parameter will also depend on the elasticity of the material: for example, for greater efficiency, rubber gaskets should be preferred over conventional rubber ones.
The installation of the plasterboard structure itself will consist of several steps:
In principle, the installation, as well as the general operation of the vibration suspension, is not much different from the use of a standard direct mount. The main thing here is to choose the right fastening material, which should be fully combined with the type of ceiling used. The connections of the vibrating suspensions themselves with the frame profile should be carried out by means of self-tapping screws or press washers. As a result, it should always be remembered that in the conditions of an apartment building, when using vibration suspensions, 100% sound insulation will never be achieved. However, their use can make the life of apartment residents much more comfortable in conditions of the lowest possible ambient noise.
