When choosing acoustic materials, we often don’t know how to choose when facing sound insulation panels and sound absorption panels. First of all, sound insulation and sound absorption are two concepts. In terms of sound insulation, it means blocking indoor sound and reducing it when it is passed outside, or it means reducing it when it passes from outside to indoor. The relationship with sound can be said to be a reflection state. The relationship between sound absorption and sound is a linear state. Sound absorption is to absorb noise and noise, so that the sound quality becomes clearer. The following explains sound-absorbing panels and sound-insulating panels from the perspective of materials, noise reduction effects, noise reduction principles, and installation and use environments.
1. Different materials
Sound-absorbing panels are generally porous structure materials, including rubber-plastic sound-absorbing panels, rock wool sound-absorbing panels and wooden sound-absorbing panels, with many tiny holes inside to absorb sound. The sound insulation board must be a high-density material, and the sound is difficult to penetrate. The sound insulation board is made of high-density materials, and the appearance is generally untreated. It is usually completed by compounding several boards or sound insulation felts.
2. The noise reduction effect is different
The sound-absorbing panel has a sound-absorbing effect, and the sound-absorbing material can absorb sound waves through repeated internal consumption, convert sound energy into heat energy consumption, and achieve the purpose of reducing noise. Sound insulation materials such as sound insulation boards can block the propagation of noise sound waves, and achieve the purpose of reducing noise and environmental governance by blocking the propagation and development paths.
3. The principle of noise reduction is different
The noise and sound waves absorbed by the sound-absorbing board can be reduced by continuous friction with countless holes in the material to reduce noise; while the sound-absorbing board has a considerable degree of vibration reduction effect by reducing the penetration of noise and sound waves. The sound insulation board is a kind of high-density sound insulation material. The use of the sound insulation board can effectively manage and organize part of the noise to radiate outward information transmission. Its biggest feature is that the maximum sound insulation can reach 30 decibels.
4. Different environments for installation and use
It is necessary to use sound-absorbing panels in places with high reverberation noise such as concert halls, recording studios, and conference rooms. For the relatively large noise value, it is impossible to effectively reduce the environmental noise through the interior of the building. You can choose to use a sound insulation board to isolate the noise in a space.
