How To Install The Ceiling Sound-Absorbing Board?

With sound absorbing cotton, when the ceiling keel frame is down, the sound absorbing cotton should be filled into the gap between the ceiling keel frame in the middle of the ceiling ceiling ceiling ceiling. In fact, the gap between the floor slab and the ceiling ceiling ceiling ceiling ceiling ceiling ceiling ceiling ceiling ceiling should be full. The space filled with sound absorbing cotton should be at least 8-10 cm, otherwise the filled sound absorbing cotton is too thin and has no expected effect. In general, all the finished surfaces of the ceiling construction should be at least 12~13 cm outside, Originally, the height of the commercial and residential floors was not too high, which would be more and more oppressive. If the sound insulation blanket is used, the sound insulation blanket can be directly pasted on the ceiling of the suspended ceiling during the construction, followed by a wooden dragon, followed by a layer of 9 cm board, followed by a full layer of sound insulation blanket on the 9 cm board, and finally, the gypsum board wood veneer is locked. All the completed surfaces of the construction only need about 6-7 cm, less than half of those filled with sound absorption cotton.
It is better to assemble sound insulation suspended ceiling for sound insulation and noise reduction. Sound insulation suspended ceiling is mainly composed of sound absorbing materials, which have extremely weak performance of absorbing and digesting sound and reducing noise. It is one of the components of ultrasonic inspection equipment. The sound absorbing material should match the resistance with the sound characteristics of the surrounding sound transmitting chemicals, so that the sound can enter the sound absorbing material without vertical plane, and most of the emitted sound can be absorbed and digested. No harm to human body.
It is strongly recommended that some methods to help house decoration: for the home owners with suspended ceilings, suspended ceiling shock absorbers can be used, and the ceiling is paved with wave crest welding machine sound absorbent cotton to prevent noise caused by upstairs residents. We can use rubber strips or plastic steel profile rubber strips to encapsulate the gaps between aluminum doors and windows. All that noise is cut off. In general, in order to be able to quickly decorate the background wall, which is an offensive noise, we should learn such methods.
All sound insulation materials can't solve the problem you mentioned. Complete sound insulation must make the interior space design closed. This kind of interior space designer can't live daily. The raw materials for sound insulation and noise reduction include sound absorbent cotton, sound insulation blanket and artificial board. The sound is carried out according to the way of projection, so select some soft sound insulation materials, you can also grasp the nvh noise reduction in the automotive field. Cancel it according to another sound.
