Home theater decoration design can be said to be one of the problems that people must consider when installing home theater. Many people do not know much about home theater, so they are easy to consider when setting up home theater, and they often misplace equipment. And in the purchase of materials there will also be the problem of buying a high price at a high price. Here are a few common questions about the improper design of home theater decoration and things to be aware of:
First, the audiovisual environment is not appropriate
I believe that many enthusiasts have experience in the purchase of equipment, and can also buy high-performance equipment at low prices, but I often hear people say that the equipment they bought is already very good, and they have already seen it at the time of purchase. I liked the sound, but when I got home, I found the sound "deteriorated." In fact, the problem of sound deterioration is mostly caused by improper audio-visual environment.
If the room is too big, too small, or sound and sound is not done well, it will cause problems with the sound. Therefore, you need to find a professional audio-visual company according to your audio-visual room design, and also need to fill the sound-absorbing materials, in order to ensure a good audio-visual environment.
Second, improper selection of sound absorbing materials
Most people know about the sound-absorbing measures in the design and decoration of home theaters. However, when choosing sound-absorbing materials, most people will not choose them. If you choose one by one, it will often be counterproductive. Generally, you should choose thicker sound-absorbing materials. Suitable for absorbing low frequency sounds, while thinner materials are suitable for absorbing high frequencies.
Among them, carpet is the most common sound absorbing material. The carpet has obvious absorption effect on medium frequency and medium frequency, and has little effect on low frequency absorption. If the area is too large when the carpet is set, the details of the sound will be lost, so the size of the carpet must be moderate.
Third, the proliferation measures are not doing well.
When the audio-visual environment and sound-absorbing materials are properly selected, the sound is still harsh and not stable enough. Most of them are due to the lack of diffusion measures. The diffusion is to smooth the sound of the rock that is like the rugged rock into the beach. Feeling like it.
If the audio-visual room is not a good diffuse sound field, the sound in different places or different frequencies in the room will be uneven. Some frequencies or some positions are especially strong, while others are very weak, which will cause it to be restored from the speakers. The flat frequency response is ruined, so the home theater must have the characteristics of a diffuse sound field. For example: cylindrical, triangular, hemispherical, polyhedral, pyramidal and other objects are good diffusion materials, but it should be noted that the material of the diffuser should be as large as possible and have certain rigidity, such as concrete, plastering masonry. Body, marble, granite.
Fourth, there are errors in the way to reduce noise.
The noise in the space is inevitable. Many people may think that the sound absorption has removed the noise. In fact, the sound absorption only removes a part of the noise. In order to achieve the best audio and visual sound, it is necessary to take sound insulation measures. Sound insulation is necessary for people to install a home theater. One of the things to do. Therefore, when designing a home theater, it is necessary to soundproof the doors, windows, glass, etc., for example, if a double-layered door is installed and the sound-absorbing material is filled in the middle, the sound insulation effect will be more obvious.
In addition, the windows of the audio-visual room can be transformed into two or even three-layer glass windows. The glass and the frame are connected by a special-shaped rubber strip, and the sound insulation performance can be compared with the brick wall effect of 24cm thick. In addition, it is also possible to stick sealing strips on the door seams and window slits. This is the easiest way to handle sound insulation.
The audio-visual effects of home theaters are not only related to the choice of equipment, but also related to the design and decoration of home theaters. Therefore, people must pay more attention to the decoration. They should not blindly choose materials for design and decoration, so as to avoid leakage, it is best to choose professional. The audio-visual company can ensure the best effect of home theater. More home theater knowledge, all in China's home theater network official micro-signal: cnhifi.
The Air Conditioner Motor is what turns the fan blades that cause air to move through the AC system. It is an essential part of the AC unit because it both removes warm air from the interior and blows cool air through the vents. Because of this, the air conditioner motor is an absolutely essential part of any AC system.
