Going to the cinema to watch a movie is troublesome, but it would be a wonderful thing if you could feel the shocking effect of the cinema at your own home. Nowadays, decorating a home theater at home has become a reality, and many people have installed a home theater in their living rooms. However, there are many things that need to be paid attention to when designing and decorating.

Here, we follow the principle of building a home living room into a listening room with good acoustic performance, as well as a living room with beautiful decoration and warm atmosphere. Here are some decoration suggestions for friends who want to decorate their new homes.

1. Treatment of doors and windows (purpose of treatment: sound insulation, sound absorption and dust prevention)

1. A lot of noise enters the room through doors and windows. A good wooden door, when closed tightly, can reduce the indoor noise level (10-20) db.

2. Cover the door frame with sealing tape, which can reduce the total noise level (14-18) db. .

3. If the sound outside is noisy, it is recommended to install double-layer windows.

4. If conditions permit, aluminum alloy windows can be installed in a push-pull type, which saves space, is easy to use, is not easy to deform, has good sealing performance, and has better performance than steel windows.

5. If air conditioning is installed in the home, the air conditioning duct is the air inlet and the noise entrance; if a TV room antenna is installed, the antenna entrance is also the noise entrance. These pipes and interfaces should be muffled.

6. Curtains, hanging curtains and tapestries are important sound absorbers, and they are also relatively exquisite and luxurious decorations. Using velvet and velvet as materials for curtains and curtains can reduce the reflection of sound waves and the vibration of glass windows. The sound absorption coefficient of curtains made of velvet is 0.31-0.47, the sound absorption coefficient of curtains made of medium-long fibers is 0.15-0.27, and the curtains made of double-layer velvet have the highest sound absorption coefficient, up to 0.69-0.82.

2. Treatment of all sides of the room (purpose of treatment: sound absorption)

1. Conduct sound insulation and sound absorption treatment on the ground. It is best to lay carpets, which have ideal sound absorption and sound insulation effects. Usually, the sound absorption coefficient of ordinary Chinese fiber carpets is about 0.5-0.71, while the sound absorption coefficient of real wool carpets is about 0.68-0.82

2. It is recommended to lay the floor without carpeting. The sound absorption coefficient of wooden floors is about 0.03--0.05. It is not recommended to lay plastic bricks or ceramic tiles, as their sound absorption and sound insulation properties are poor.

3. Treat the four walls.

Ordinary walls are dry plastered brick walls, and their sound absorption coefficient is very small, about 0.02--0.04. The four walls can be made into wooden walls; or made into wooden dados, the height is (0.8 --1) m. The dado should be kept at a certain distance from the wall, not less than 4cm. A cavity is formed between the panels and walls, which can increase the low-frequency sound absorption effect.

The walls should be painted white or sprayed with gray, latex paint, colored spray or other coatings. Their sound absorption effects are similar.

If conditions permit, you can hang decorative cloth on the wall. The distance between the wall cloth and the wall is (3-5) cm. This kind of wall covering can enhance sound absorption and beautify the room.

3. Indoor furniture arrangement (processing purpose: optimizing sound reflection)

1. Overall layout

Many home listening rooms can be used to enjoy music, and To receive guests, audio-visual enjoyment and aesthetics must be unified. At present, the height of ordinary rooms is relatively low, only (2.4-2.8) m. In order to take into account the listening effect, the length and width should be close to 1.7:1. Generally, the area of ??the listening room is larger than 15 square meters, so that when playing back stereo sound, the distance between the two speakers should be about (2-2.5) m, which is conducive to the expansion of the stereo image group.

2. Decoration skills

① The placement of indoor furniture should strive to be easy to use and beautiful in the room. When arranging furniture, try to avoid symmetry to avoid sound staining.

② Do not place objects that cause vibration indoors, such as metal paintings, thin and light displays, etc. Their vibration will affect the sound playback effect.

③ Placing modular cabinets, bedroom cabinets, large sofas, etc. in the room can obviously improve the sound absorption effect, especially the low-frequency effect. Generally, a perforated plate resonant cavity cannot be installed in a living room, so it is inconvenient to absorb low frequencies. This shortcoming can be overcome by placing a wardrobe.

④Thick curtains on the glass windows, tapestries on the walls, carpets on the floor, and bedspreads on the beds can all improve the acoustic conditions. Curtains have better low-frequency transmission performance, while glass windows have better low-frequency sound absorption performance, and they have a complementary effect.

3. Fine-tuning of reverberation time

① Indoor reverberation time should be controlled within a certain range. If the reverberation time is too long and the sound has tailing and echo, you can increase the sound absorption by laying carpets, hanging decorative curtains, etc. You can even improve the sound absorption effect by placing rag dolls, velvet toys, flower pots, etc. indoors.

② If the indoor reverberation time is too short (this situation is less common in ordinary living rooms) and the sound is dry, you should increase the reflective surface, such as hanging glass mirrors or pictures with large glass frames, etc. Improve indoor sound quality. There are many ways to improve sound quality. For example, hanging various chandeliers indoors, pasting calligraphy and paintings on the wall, or hanging handicrafts, etc., not only beautifies the environment, but also improves the reflective properties.

③ Bookshelves are placed indoors, and the bookshelves are filled with books, magazines, CD records, analog records, etc. of various sizes. These items have the properties of absorbing, reflecting, and scattering sound waves. Sex; placing books of different sizes and widths on each floor of the bookshelf can produce irregular surfaces. For those large-area reflective walls that are difficult to deal with, try placing this kind of bookshelf, which can also improve the listening effect. In short, through various adjustment measures, people will finally hear the beautiful and harmonious sound coming from the speaker.
