If the interior decoration is not reasonable, even if you have the most advanced home theater configuration, you will not be able to enjoy real music. It's like moving a hi-fi set to the bathroom to play the sound. You will find that it is really unbearable to "listen" to it. (1) Room selection When sound propagates indoors, it often stimulates certain frequencies to produce vibrations to form "standing waves". This kind of vibration greatly affects the effect of the audio-visual room. The distribution of "standing waves" is related to the geometric dimensions of the room. In order to avoid the "standing wave" phenomenon, it is best to choose a rectangular shape for the audio-visual room. Also choose appropriate proportions and shapes. Of course, if the room size is a foregone conclusion and difficult to change, you can increase the room interface damping to reduce the vibration intensity. (2) Door and window treatment The purpose of door and window treatment is sound insulation, sound absorption and dust prevention. Most outdoor noise enters indoors through doors and windows. A good wooden door can have a good sound insulation effect. Install double-pane windows to block out outdoor noise. Through the barrier of double-layer glass, the noise entering the room can be significantly reduced. The air conditioning duct is the entrance to the air inlet antenna and also the entrance to the noise. These pipes and their connections should be muffled. Curtains and curtains can be made of velvet and velvet materials, which can reduce the reflection of sound waves and the vibration of glass windows. (3) Treatment of all sides of the room First, the ground must be sound-insulated and sound-absorbed. The best way to deal with it is to lay carpets, which have ideal sound absorption and sound insulation effects. Erecting wooden floors is also a better choice. Of course, many families have already laid plastic tiles or ceramic tile floors, but their sound absorption and sound insulation properties are relatively poor. Secondly, the four walls must be treated. Ordinary walls are dry plastered brick walls, which have a very small sound absorption coefficient and are not conducive to listening to music. In this case, you can make the four walls into wooden walls, but if conditions permit, you can hang decorative fabrics on such walls. . This kind of wall covering can enhance sound absorption and beautify the room. Finally, the ceiling is also an important way to introduce noise. Ceilings that are of poor quality and have thin slabs tend to transmit noise.

It is best to install a sound-absorbing ceiling with high strength and good structure on the ceiling. It not only looks good, but also has sound absorption and sound insulation effects on the audio-visual room. It can also improve the proportional characteristics of the room
