Car Sound Deadening Material

Specifications

Sound insulation foam is a kind of very mature technology and low cost solutions to reduce noise.It is common sponge after high pressure molding.

Sound insulation foam Was first applied in the recording studio, conference room, KTV and other places, as people increasingly demands of quiet and comfortable living environment, sound insulation sponge begin to enter the family, as metope subsidiary structure, which can satisfy the need of you to create a tranquil environment, but also has certain ventilation.

Principle of sound insulation, sound insulation foam is to make the sound bounces back and forth to reduce the noise in the sponge, we have learned, when laying area of more than 3 square metre, can achieve a good sound insulation effect.Sound insulation foam is made of high density sponge density more than 30 kg, with good appearance and good acoustic characteristics;By sound wave bounces back and forth in the sponge to absorb low to more than 500 hz frequency of sound, greatly reduce the conductivity of the voice.Scope of application: speakers, audition room, surveying and mapping room, KTV rooms, star hotels, etc used sound-absorbing, sound insulation, shockproof, fire prevention.

 
Unique shape wave sound-absorbing sponge, used in acoustic noise reduction.Its absorption ability is very strong, for high frequency can also be used to deal with the sound-absorbing, and demanding playback in the room, control room, for example, mixing room, listening room, home theater, etc.Crest sound-absorbing sponge is also often used in precision instruments, electronic instrument packaging.As a packaging mat, it can be a very good buffer vibration, protection equipment, at the same time the characteristics of the flame retardant, also put the instrument more safety.
