With the continuous development of the film industry and people's continuous pursuit of spiritual life, people began to set up private home theater audiovisual rooms at home. Most of them do not understand the knowledge of audio-visual room decoration design, which will make the audio-visual equipment not achieve the expected effect. The following is to introduce some details that should be paid attention to in the acoustic treatment of the decoration design of the home audio-visual room:
First, the ground
Tiles: easy to cause high-frequency harshness.
Stone: same as tiles
Wooden floors:
1. Lay the wooden board directly on the cement floor, the sound effect is similar to the effect of the tile floor
2. Nailing the wooden floor overhead into a cavity will have a good absorption capacity for frequencies below 100Hz, and the low-frequency effect of the sound will be very good. If you can lay small stones under the floor, you can fill the gaps that are easy to cause standing waves and resonance, and even the disadvantages of cavity wood floors can be overcome.
3. The ground adopts wooden keel base layer with a height of 50-100mm, and the hollow layer can be filled with soft materials, but pay attention to water treatment, and lay cork flooring on the keel surface (while strengthening the sound absorption effect in the room);
Second, the wall
"The front wall is hard, the left and right side walls absorb sound, and the back wall spreads"
1. Front wall: To make a hard block, you can save a certain low frequency, so that the low frequency can be better extended forward.
2. Sound absorption on the left and right side walls: ensure clear sound positioning and pure sound quality
3. Back wall: processed into sound absorption and diffusion. However, it is recommended that the chair is preferably more than 0.6m away from the back wall, and the sound-absorbing material is glued to the diffuser plate, which can make the absorption and diffusion of sound both.
4. Wall corner: It is the place where the standing wave is strongest, and the special items such as bookshelves and CD shelves placed in the corner of the ground wall can greatly help the sound
5. The wall adopts a wooden sound-absorbing board surface layer, and a 50mm polyester fiber sound-absorbing cotton is laid on the back, and then a 50mm air layer is reserved;
