We Provide New Generation Solutions We Are Applied In The Areas That Must Be Protected From The Harmful Effects Of Noise In Sound Insulation.

How Does Sound Insulation is Practiced?

Sound insulation; in areas where protection from harmful effects of noise (housing, school, hospital, dormitory, hotel, business, etc.), in areas where the noise they emit to the environment must be prevented (generator, hydrophore, heater, high-volume entertainment places, etc.) areas (cinema, theater, concert and conference hall, TV and sound recording studio, etc.). 

Sound insulation

Sound or noise; It is a type of energy that spreads by creating vibrations in gases, solids and liquid environments. Sound transmission in structures basically occurs in two ways;

1-) Airborne sound transmission,

2-) Pulse induced sound transmission 

Airborne sound transmission: Sound waves move through the air, causing the building element to vibrate.

The vibrations are transmitted to the volume adjacent to the sound source by moving through the building element or through various gaps in the building element. Examples of typical airborne sound transmission are speech, listening to music, and so on. activities.

Impact-induced sound transmission: When an object strikes the building element (wall, ceiling or floor), both surfaces of the building element vibrate to produce sound waves and sound is transmitted to other volumes outside the volume of the impact. Typical impact-induced sound transmission includes footsteps, bouncing, dropping, dragging, and so on. activities. Different methods are used to limit airborne and pulse induced sound transmission.

If the sound waves encounter an obstacle of different density or flexibility than the environment in which they are traveling, some of the energy is reflected, some of them are absorbed and turned into heat and some of them continue their way. Sound insulation also consists of applications that prevent the passage of sound waves reflected from all parts of buildings.

The single-layer structural elements counteract the passage of airborne sound to the neighboring space with their masses. This is called the law of mass. Thus, the higher the weight of a wall, the greater the loss of sound transmission. However, this method to provide sound insulation; it will not be economical and functional due to overload to the carrier system, loss of space due to the formation of sound bridges and thickening of that wall. As an alternative to such single-layer partition walls, double-walled lightweight partition walls are now being used. These walls consist of a sound-absorbing material placed between a carrier construction and thin coatings fixed on both sides. In existing buildings, internal insulation, sound insulation material is fixed to the building element with profiles or glued and coated on it.

It is also necessary to prevent the impact sounds such as footsteps, goods pulling sounds from passing into adjacent, lower and upper spaces. For this purpose, floating flooring applications are made with suitable materials.

Prevention of impact sounds is only possible with the application of a double-layer flooring. For this purpose; Sound insulation materials are placed on the flooring. Then, the sound insulation material is continued on the walls up to the baseboard level in such a way that the handle and floor covering to be formed is contacted with the concrete floor and wall elements. In this way, the floor on which people will move will be cut off from contact with the walls, and it is ensured that they are taken into a pool of sound insulation materials. Thus, the sound bridges that cause direct or indirect transmission of sound are eliminated. This system is called as floating floor ”.

The location and design of the structures are also important for noise prevention. Residential areas should be located as far away as possible to avoid noise from motorways, airports and railways. Again, natural or artificial sets may be formed between the noise source and the settlements. Avoidance of U-type buildings and courtyards that will cause reflection are also measures to be taken against noise.

When determining structural elements such as walls and windows, materials with high sound insulation properties should be used. Otherwise, it will be difficult to implement the transactions to be made, in some cases will have impossible results. Noise control methods in building glazing; The use of laminated and acoustic laminated glass panels to increase the thickness of the glass, the use of specially designed insulating glass units and double-glazing glazings for noise control instead of single glazing. Preventing sound leaks by using thick, heavy and gapless doors is important for sound insulation. 

Apart from these, decoration elements such as curtains and carpets are a little effective in preventing sound transmission.

In the installations, sound insulation can be made in order to prevent the noise arising from the flow and the noise and vibration caused by the operation of the elements such as fans and pumps. Floating pedestal details and vibration isolators are used to prevent vibrations generated by the machines in operation to the main construction. Special precautions should be taken to prevent vibration in details where installation pipes penetrate structural elements such as walls or floors. In addition, special insulated clamps should be used to prevent the installation pipes hanging on a surface from vibrating and transmitting sound to the structure.

The use of a noise barrier to reduce traffic noise is also among the methods used against noise. The efficiency and sound of the works related to sound insulation depends on the fact that they are handled at the planning stage. Measures such as gathering structures such as industrial facilities, entertainment places, dwellings, dormitories, hospitals in certain regions and creating areas such as airports, railways and highways in certain regions can be provided during the planning stage. In this way, it is possible to reduce the expenditures by choosing the places where the structures will be built more healthy.

When planning the structure, it will be useful to distinguish between contradictory spaces such as bedrooms and living rooms in terms of usage purpose and sound level.

The process to reduce the amount of sound transmitted through the building elements is called “Sound Insulation” and the regulation of the reflection time in the current indoor environment is called “Acoustic Regulation”. Unfortunately, these two concepts are confused. In particular, mistakes made by non-experts who do not know how to use the right material in the right detail can lead to misinterpretations about the materials.
