Three major differences between soundproof cotton and sound insulation panel

When choosing sound insulation materials, many people will be more curious about the difference between soundproof cotton and sound insulation panel
1. The principle of sound insulation and noise reduction
soundproof cotton Sound insulation noise reduction is by absorbing sound waves and countless holes in the material friction noise consumption. Its principle is that the object vibration produces sound wave in the air transmission cotton with multi-fiber structure sound wave through the cotton through countless fiber reflection, mutual superposition, collision, sound wave energy into thermal energy sound wave intensity weakened the sound disappeared.

And sound insulation panel is to reduce the penetration of noise sound waves, has a certain degree of vibration reduction effect.sound insulation panel Is a kind of high-density sound insulation material, the use of sound insulation panel can effectively organize a part of the noise outward radiation transmission, its characteristic is that the sound insulation can reach 30 decibels.
2. The use environment is different
soundproof cotton Mainly used for car sound insulation, sound insulation panel is mainly used for indoor and various places. In noise control, when we use sound insulation panel and soundproof cotton, we need to choose the appropriate ones according to different situations and noise reduction requirements.
3. different effects
soundproof cotton With the sound elimination effect, can absorb the sound waves through the internal repeated consumption, the sound energy into energy heat energy to consume noise to achieve the purpose of noise reduction.
