1. Choose a better room and a better location

Home theaters and rooms for listening to music are preferably rectangular in shape, and the room size is as large as possible. However, due to limited living conditions, there may be a variety of unsatisfactory room shapes and areas. Be careful to place the left and right sides of the main speaker as symmetrical as possible indoors. The square room is not ideal, and the main speaker can be placed symmetrically around the corner. The audio equipment and audio-visual position should be at the longer ends of the room. The distance between the two main speakers should be no less than 2 meters and an isosceles triangle or an equilateral triangle with the viewing position. The front of the main speaker should be slightly turned to the inside. The glyph, the outer side and the back are better than the space of 0.3 m each. The height is generally higher when the tweeter is slightly higher than the height of the ears when sitting.

2. Reasonable selection of sound absorbing materials

It is better to consider some materials with certain sound absorbing functions when decorating the living room, such as non-woven wallpaper, wallpaper with embossed pattern, etc. However, it should also be noted that the sound absorbing materials should not be overlaid too much, otherwise the sound will be dry and dry, lacking a round and pleasing spatial sense, and will also lose the charm of music. If the living conditions are limited, it is impossible to create a home theater or listening room. In the living room, the sound and home theater or listening environment are selected. If the study or bedroom is used as a home theater or listening environment, the effect may be greatly affected. If one side is a cement wall and the other side is a large cabinet type of furniture, it is necessary to hang one or two sound-absorbing fabric decorative paintings or tapestries on the side of the cement wall to make some acoustic compensation treatment, so that the main speaker The acoustic performance on both sides is as close as possible to symmetry.

3. To fasten doors and windows, soundproof and vibration proof

Enthusiasts have the experience that if the sound is loud when listening to music, a certain part of the room such as doors and windows or other small objects will sizzle along with a certain frequency of music. If this kind of resonance phenomenon is to be effectively avoided, it should be noted that the indoor ceiling cannot be made into a cavity type, the furniture is also less preferred, and the open cabinet furniture should be avoided, because it is actually a cavity; in an acoustic environment It is also not appropriate to place lightweight shell craft ornaments. The glass of the doors and windows (including the door glass on the furniture) must be securely installed and pay attention to the gasket at the gap. If the listening environment is facing the street or near the downtown, the noise is too loud, and soundproof measures should be taken. In addition to sealing the gap between the doors and windows, it is better to change the door and window glass to double layer to greatly improve the sound insulation performance. In order to reduce the vibration to a lower level, it is possible to use the "I" or "Z"-shaped speaker stand to erect the speaker. Unconditional speakers can also be placed on the low cabinet, but the low cabinet is better and firmer, and the inside should be full article.

4. To use the power line

The watt-hour meter in the home should be changed to 5 amps or more. Audio power, kitchen electricity, lighting power, air conditioning power, etc. must also set up separate lines, so as not to affect each other. If the conditions are limited, at least a dedicated line should be set up separately for the audio equipment, and it should be used at the same time as other household appliances. Otherwise, vacuum cleaners, hair dryers, microwave ovens, computers, air conditioners, etc. will generate electrical clutter, causing noise to affect audiovisual effect.
