Which effect is better, sound insulation board or sound insulation cotton? What is the difference between sound insulation board and sound insulation cotton
Sound insulation board and sound insulation cotton are two common sound insulation materials on the market. Many new friends don’t know the difference between the two. Which effect is better? Now I will introduce sound insulation board and sound insulation cotton. Where is the difference.
1. Different noise reduction principles
The noise sound waves absorbed by the sound-absorbing board are reduced by friction and consumption with the numerous holes in the material; while the sound-absorbing board reduces the penetration of the noise sound wave and has a considerable degree of vibration reduction effect. The sound insulation board is a high-density sound insulation material. The use of the sound insulation board can effectively organize a part of the noise to radiate outwards. Its biggest feature is that the sound insulation can reach 30 decibels.
2. The installation and use environment is different
When we use soundproof panels and sound-absorbing cotton in noise control, we need to choose suitable soundproof and sound-absorbing materials according to different conditions and noise reduction requirements.
3. Different noise reduction effects
The sound-absorbing cotton has a sound-absorbing effect. The sound-absorbing material can repeatedly consume the absorbed sound waves internally, and convert sound energy into heat energy to consume noise to achieve the purpose of noise reduction. Sound insulation materials such as sound insulation boards can block the propagation of noise sound waves, and have been blocked at the transmission path to achieve the purpose of noise control. The noise reduction effect is very poor.
