The difference in the structure of materials: sound-absorbing material: there will be many interpenetrating micropores in the sound-absorbing material, and the micropores are connected in series from the inside to the outside and the outside to the inside. Blow on one side of the sound-absorbing material, and feel it with your hand on the other side. If the density is high, it will not be able to blow through. Sound insulation material: The structure of sound insulation material and sound absorbing material is just the opposite. There is no gap or aperture, but it is dense. Since the material of the sound insulation material is dense and heavy, the sound insulation material cannot absorb sound energy.
Grooved wood sound-absorbing board. The difference in the working principle of the material: Sound-absorbing material: As mentioned above, the sound-absorbing material has many micro-holes through it, so when the sound enters these micro-holes, it causes the air in the micro-holes to vibrate, and the sound will be different from the micro-holes. The friction of the hole wall in the hole, coupled with the air resistance of the micro-holes and the heat conduction effect, can convert the sound entering the sound-absorbing material into heat energy, which has a good sound-absorbing effect. Sound insulation material: The working principle of sound insulation material is exactly the opposite of that of sound absorbing material. Sound insulation material does not need to absorb and convert sound, but directly isolates noise. Because sound insulation material itself is very dense, sound cannot pass through, so it only Sound insulation does not absorb sound, but if the sound insulation material is used alone, the indoor reverberation will be very large, so the indoor sound insulation material and sound absorption material are used together.
Wooden sound-absorbing panels are a new type of indoor sound-absorbing and noise-reducing materials, which are widely used in our lives, including home theaters, bedrooms, living rooms, schools, conference rooms, and many other places. However, after the wooden sound-absorbing panel is decorated on the wall, like other decorative materials, it will also become dirty after a long time of use, so it is necessary to clean and maintain the wooden sound-absorbing panel, but how to do the cleaning and maintenance of the wooden sound-absorbing panel? ? Let’s popularize the following acoustics: cleaning and maintenance methods for wooden sound-absorbing panels: The dust and dirt on the ceiling surface of wooden sound-absorbing panels can be cleaned with a rag vacuum cleaner. Please be careful not to damage the structure of the sound-absorbing panels when cleaning.
Use a slightly damp cloth or a sponge wrung out of water to wipe off the dirt and attachments on the surface. After wiping, the moisture left on the surface of the sound-absorbing panel should be wiped off. Ensure that the storage environment of wooden sound-absorbing panels is clean, dry and ventilated, pay attention to rainwater, and beware of moisture-absorbing deformation of the sound-absorbing panels. If the sound-absorbing panel is soaked by air-conditioning condensate or other leaking water, it must be replaced in time to avoid more losses.
