What is Sound Insulation?

Sound insulation is the process of reducing or blocking noise coming from inside or outside a building or space. This process is essential for creating a comfortable environment in noisy surroundings, meeting legal requirements, and conserving energy.
Sound insulation is achieved by adding or modifying suitable materials in the building components. These materials can be of different types, such as acoustic panels, sound insulation barriers, or sound insulation mattresses. Sound insulation typically blocks high-frequency sounds, but preventing low-frequency noises is more challenging.

How is Sound Insulation Done?

Sound insulation is done by adding or modifying suitable materials to building components such as walls, ceilings, and floors. The choice of materials should be based on the characteristics of the space. Materials used for sound insulation can be of different types, such as sound insulation barriers, sound insulation mattresses, or acoustic panels. You can contribute to sound insulation indirectly by placing acoustic panels and absorbers without incorporating them into the construction.
A floating room is considered the most effective method for sound insulation. This method is ideal for studio recording or high-volume music applications.

A floating room is a structure that prevents its materials from being exposed to vibrations or shaking. In this way, outside noise is prevented from reaching the interior, and the spread of internal noise is reduced.

A floating room has a double-walled structure. A specialized insulation material is used between the two walls. Additionally, the floor and ceiling are also insulated. As a result, the sound inside does not spread outside, and the outside noise does not enter.

Building a floating room is a task that requires expertise and experience. A professional company or expert will provide the best results with the right material selection and the proper application method. Therefore, it is recommended to seek professional help for building a floating room.

Although the floating room method is the most effective method for sound insulation, it is more costly than other methods. For this reason, floating room methods are primarily used in professional spaces such as music studios, radio, and television studios.

Sound insulation depends on many factors. For example, factors such as the frequency range of the insulation, the location of sound sources, and the thickness of the insulation material should be considered.

Why is Sound Insulation Necessary?

Sound insulation is essential because high noise levels in living or working spaces can cause problems such as sleep disorders, decreased work productivity, lack of concentration, and emotional discomfort. With proper sound insulation, these issues can be prevented, and people can live in a more comfortable environment.
Additionally, sound insulation is vital due to legal requirements. Some buildings, especially workplaces or residences, must comply with specific sound insulation standards. Non-compliant structures can pose a risk to the health and comfort of surrounding individuals and can lead to legal issues.

Lastly, sound insulation conserves energy. Good sound insulation not only reduces outside noise but also decreases indoor energy loss. This results in energy savings by reducing heating and cooling costs. Therefore, sound insulation is crucial for people’s health, comfort, and energy conservation.

How is Sound Insulation Measured?

Sound insulation can be evaluated with measurements like STC (Sound Transmission Class) or NRC (Noise Reduction Coefficient). STC is a measurement used to determine how much sound insulation a building element provides. A building element with a high STC value provides higher sound insulation. NRC is used for measuring properties such as reverberation time and echo delay on the surface of the material. A material with a high NRC value provides better acoustic performance.

What Materials are Used for Sound Insulation?

There are many different options for materials used for sound insulation, including acoustic panels, sound insulation barriers, sound insulation mats, and sound insulation boards. These materials are added to building elements to provide sound insulation.
Acoustic panels are cladding materials placed on walls or ceilings to provide sound insulation. Sound insulation barriers or mats provide sound insulation by being placed in gaps between building elements or on walls. Sound insulation boards are used by placing them around noise-emitting devices.

How Much Does Sound Insulation Cost?

Sound insulation can be achieved at different costs depending on the type of materials used, the size of the space, and the details of the work to be done. Therefore, the cost varies depending on the budget of a project.
