KTV room sound field needs attention when decorating

The sound field of the KTV private room has certain special characteristics. For example, the room is small, it is easy to cause whistling, the private room is next to each other, and it needs sound insulation. At the same time, because it is the night field, it is necessary to consider the sound of the whole sound field. Isolated effect. Therefore, good acoustic design must be considered.
(1) Use heavy walls to block the soundproofing source between the loud hall and the private room. The sound insulation should be done between the private room and the private room. It is generally recommended to use cement-filled hollow bricks to build the sound wall.
(2) The partition wall is built on the top of the cement ceiling. Many people use the method of first ceiling and rear partition wall in order to save cost and convenience, so that the upper part reserves air conditioning duct, exhaust duct, fire pipeline and power wire pipeline. After the ceiling, not only is the construction extremely laborious, but also the trouble of the reinforcement of the pipeline and the top seal of the sound insulation wall. A reasonable construction plan is to construct the pipeline first, then build the wall, seal the wall, and then suspend the ceiling.
(3) The proportion design of the muffling wall should be reasonable. Many people know that designing some muffling walls in the private room can alleviate the whistling of the microphone, but sometimes the excessive emphasis on the sound absorption effect will cause the microphone to have insufficient reverberation. Dry up, so as to affect the overall singing effect. Therefore, there should be some sound reflection in the private room, for example, the design of the hard floor, the design of the wall using the imposition of the wood, can solve the situation of insufficient reverberation.
(4) The design of the ceiling is generally recommended to be simple. In the case of handling the strength of the ceiling frame, especially the strength of the speaker hanging position, and the mark should be made. The top is made of gypsum board and the surrounding is made of gypsum. The module uses a lightweight wooden geometry substrate throughout the week. This can be combined with a hidden three-base color lamp to form a combination of light refraction.
(5) It is best to use a double-glazed glass door for the sound-insulating glass door that handles each door and window. The doors of each room should be soundproofed, usually made of multi-layer wood, with sound-absorbing materials on the outside, and leather-coated materials, plus positioning nails.
(6) Reasonable layout of the speakers, which can reduce mutual interference. The general design is that the adjacent two rooms of the private room are hanged with back-to-back design, while reducing the back panel of the speaker to touch the wall, which is convenient for wiring and power supply. It can also reduce the interference of sound.
(7) Handling the crosstalk of the pipeline part and interfering with the interference of the air conditioning duct and the exhaust duct are particularly obvious. It is necessary to deal with the firm strength of the pipe installation part, and at the same time, consider the sealing degree of the contact part.
