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 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
1-) Airborne sound
2-) Pulse induced
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.
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
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.
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
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
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.
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
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.
