Is a TV in the living room still necessary? In the era of mobile Internet, even parents have begun to lie on the sofa and watch videos and news on their mobile phones, and the TV has been turned off for a long time. The living room cannot be idle either. It is necessary for Joule to watch variety shows and appreciate American blockbusters. Especially in big cities with huge land and huge investment, independent theaters cannot be bought, so large-screen living room theaters are more feasible.

Many audio-visual systems tend to ignore some things that they don’t care about, such as how the lines are routed, what materials are needed for sound insulation, and the most important thing is to let the stars get on. Some families like some sparkling meteors for good looks, which are really good-looking, but some of the paintings are made of different materials. Today, I will tell you how to avoid these.

1. The most taboo of lines is chaos. Audio systems are different from household cables. Generally speaking, household cables will not suffer any loss. But if you run the audio cable and the household cable together, the trouble is to burn the cable yourself. You may change course. It must be noted. The power of the audio coil is large, and the electric clang used at home is small. Once together, it will inevitably cause a small flame, or the entire line will be cut off. This is the point, everyone must remember!

2. Sound insulation materials, the most taboo are non-sound insulation materials and ordinary sound insulation materials. Glycoside materials such as glass wool, glass wool have general sound insulation effects, and are not environmentally friendly. It is a yellow object. The color of good sound insulation is pure white. Certain environmental protection, of course, this is particularly suitable for audio-visual systems, KTV, offices, hotels, now generally speaking, many people like this, it is also called fiber sound-absorbing cotton, sound insulation,

The characteristics of sewer sound insulation felt: The sound insulation cotton is made of a layer of 2MM thick low-frequency damping sound insulation felt and a layer of thick wave peak sound-absorbing cotton. The pipe sound insulation material adopts the design method of internal absorption and external isolation. The internal sound-absorbing material can well consume the echo between the pipe wall and the sound-insulating material, and play the role of heat preservation and antifreeze. The outer sound insulation material can well isolate the low-frequency noise generated by the high water flow, and the single-layer sound insulation of the sound insulation material can reach more than 40 dB. Especially in a small room environment, strong direct sound will weaken the spatial feeling of the music, and the sound will become dry and straight, similar to the feeling of headphones or monitor speakers.

Although it is really bad, but in most cases it still needs to be soundproofed and soundproofed. Sound insulation is not only to avoid disturbing the people, but also to obtain a listening environment with low noise interference.

In some basements, there are sewer pipes on the top, and the sound of running water will cause noise pollution. In addition, sound insulation should be considered when the upper basement is occupied. In response to this situation, it is necessary to wrap the pipes with sound-proof materials and isolate the sound transmission between floors with a sound-proof ceiling.

Generally, the basement is not just an audio-visual room, but other rooms also have entertainment rooms, studios and other rooms, which will disturb the neighbors. Although your family won’t complain, you should consider at least customizing a soundproof door.
