5 Types Sound Insulation Materials Explained

sound is created by the vibrating, if we need to stop the spread of sound , we need to use sound insulation materials to prevent the transmission of sound between rooms by blocking sound. Thus sound insulation materials is crucial to prevent you from being disrupted by the outside noise. To help you stop the noise from entering or leaving a room, we make a list of some practical sound insulation materials.
 

● DAMPING SOUND INSULATION BOARD

 

Damping sound insulation panel front and back adapt the different density and thickness inorganic material， which has an obvious isolation characteristic on both high frequency and low frequency. The average sound insulation is 53 dB.

 

● ECHO ABSORBER ACOUSTIC COTTON

Fiberglass cotton is a man-made inorganic fiber, which can absorb a large amount of sound energy in the room, reduce reverberation time, and reduce indoor noise. Glass fiber sound-absorbing cotton is commonly used with sound-absorbing panels and sound insulation panels to build wall acoustic systems.
Also Fiberglass cotton features flame-retardant, non-toxic, corrosion-resistant, small bulk density, low thermal conductivity, strong chemical stability, low moisture absorption, and good water repellency.

● DAMPING SOUND INSULATION FELT

The felt for acoustic panels is made of polymer metal powder, various auxiliary agents, and then pressed. It is a new type of building sound insulation material that controls the sound attenuation of noise in the transmission path. It has the advantages of burning safety, self-extinguishing after removing the flame, no dripping

1. No ozone-depleting substances
2. Does not contain lead powder and questionable oil
3. Easy to cut, glue, sew, nail or mechanically compound
4. Burning safety, self-extinguishing after removing the flame, no dripping
5. Strong flexibility and tear resistance
 

 

 

The raw material of the Vibration isolation pad is nano-foam, which is a kind of high-density foam. Its perforation rate and pore size are specially designed to achieve sound insulation, shock absorption, waterproof and moisture-proof effects. Green and environmentally friendly products with simple construction.

Product parameters

● VIBRATION ABSORBER

Its unique damping rubber block can cut off the propagation of the sound bridge, especially for places where there is a subwoofer in the entertainment city. This is an important sound insulation system accessory. Otherwise, no matter how much sound insulation material between walls is unable to block the sound in the private room.
