Sound Insulation and Acoustics
Sound insulation materials are products that keep the sound at the place where it is formed, prevent the transmission of the sound to the other places of the building and the unwanted sound from the outside into the room.
Sound-absorbing materials, on the other hand, dampen sound waves that vibrate in the environment, reducing acoustic quality, background noise and poor echo. Sound absorber materials are not used alone to prevent sound from penetrating from the outside, but significantly improve the sound quality in the places where it is used.
Sound waves create vibrations on the structural elements between the independent sections and cause sound transmission. The most practical way of preventing sound transmission is to divide the common structural element between the sections with two independent layers and to place sound absorber materials which serve as springs between the two layers. The attenuated sound waves, which can partially pass through the first layer, are absorbed in the sound absorber material to a great extent and the sound transmission is minimized by being exposed to the extra resistance caused by the mass of the second layer. This principle in sound insulation is known as "Mass - Spring - Mass Law".
CelluBOR is one of the most important components in the sound suppression system and is used as sound absorber material. CelluBOR, according to the results of the sound absorption of sound absorption class A class and sound absorption coefficient is 1.0‘. CelluBOR has the ability of soundproofing up to 70 dB according to the experiments to measure the sound insulation emitted by air according to different frequencies when applied in the system with the correct building components. It prevents reverberation and resonance thanks to its irregular and fiber texture. It creates a peaceful and comfortable environment by eliminating noise pollution.
Why is sound insulation necessary?
• Sound insulation is required to prevent noise transmission between neighbors in residential and adjoining houses, to establish comfort in hotels and offices, and to create quiet and peaceful areas.
• According to the Manage Regulation on Protection of Buildings Against Noise an published in the official newspaper, sound insulation is a legal obligation.
• Sometimes even chat or listening music can be heard from adjacent apartments. Sound insulation is required for privacy.
• It is necessary for acoustic regulation that the sound waves coming from the sound source do not reflect back and distort the existing sound in studio environments.
• It is necessary to damp the impact sounds such as mechanical sound before they are transmitted from the source.
• Noise, which can be defined as loud and irregular sound, has a negative impact on human health and the environment. Sound insulation is required for peaceful and healthy environments.
• Decontamination of living spaces makes the sound insulation environment more valuable than others.
