The transmission of sound through the building structure is divided into two ways according to the law of transmission: one is structural sound transmission. After the sound source hits the contact parts, the vibration is transmitted to the building structure, and then is transmitted through the building structure such as beams, floors, columns, and walls. In the room, for example, the noise generated by hitting the floor with your foot is structural sound; the other is airborne sound, which means that after the sound source in the air emits sound, it spreads to another space using air as a medium, such as outdoor vehicles. The sound of coming and going came into the room. Different ways of dissemination of noise are handled in different ways. Airborne sound is generally handled by enhancing the sound insulation of the building envelope, and the best way to transmit structural sound is to dampen the sound source.
This is a typical airborne sound, and the way to deal with it is to strengthen the enclosure of the wall adjacent to the noise source. First of all, we must strengthen the sound insulation of windows. Double windows, double glass windows, hollow windows, and soundproof windows can be selected according to budget and soundproof decibel needs. Use soundproof plywood to stick to the wall. Ample area can be used as a hollow soundproof wall with sound insulation effect. Better.
Aluminum foam sound insulation board is a composite board such as marble, glass, template or foam aluminum sprayed on the surface of the foam aluminum board. It is used for sound insulation and noise reduction of building walls, ceilings, and floors. Foamed aluminum has its own free sound insulation and sound absorption characteristics, and its advantages are obvious among all sound insulation materials. It can reduce the amount of noise penetrating the wall, reduce the noise decibel, and achieve the sound insulation effect.
