Fit-out and Decorative Acoustic Isolation Solutions

Sound insulation/proofing and sound absorption are two different concepts. In modern building structures, the Sound Insulating/proofing materials are dense and heavy, while the Sound Absorbing materials are porous and light. The main function of sound insulation/proofing materials is to block the sound from entering or leaving a space, whereas sound absorbing material is used to improve the sound acoustics in a space such as reducing echo and reverbirations.

Sound Insulation or materials that are used to block sound are placed inside the wall or ceiling. Sound Absorbing material can be applied as on the wall or ceiling itself and or designs and colors allow them to integrate into the overall interior design as a decorative feature.

There are three factors to generate and transmit the noise: Noise source, propagation path and receiver. Most adults can hear the noise with frequency range from 100HZ to 4000HZ. The frequency of conversation and common noise in the buildings is basically 125HZ to 4000HZ. The wall sound reduction STC refers to the sound insulation capability of wall to the noise within the range of 125 HZ TO 4000HZ.

Decibel (DB) is a unit used for expressing the sound relative intensity. Physically, the defined reference acoustic pressure(P0=2X10-5pa) corresponds to ODB. If the noise pressure is P, the noise decibel is equal to 20log(P/PO)/ So decibel is a designated unit. Similar to an earthquake’s magnitude, the higher the number is on the scale the more intense the noise will be.

The sound insulation function of a material is the capability to reduce the noise intensity. If the sound of one room is 75DB, the sound transmitted to the adjacent room through the wall will be reduced to 40DB. Therefore the sound insulation function of the wall is 35DB.
