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 isolated effect of the whole sound field. Therefore, good acoustic design must be considered.
(1) Use heavy walls to block interference from loud sound level sound sources
Sound insulation should be done between the lobby and the private room, between the private room and the private room. It is generally recommended to use cement-filled hollow bricks to build the sound wall.
(2) Partition wall to the top of the cement ceiling
In order to save costs and ease of drawing, many people use the method of first hanging the rear partition wall, so that the upper part reserves the air conditioning duct, the exhaust duct, the fire pipeline and the power wire pipeline. This method is not only extremely difficult to construct after the ceiling. Moreover, it brings great trouble to 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 and the sound to dry up, which will 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) Design of ceilings
It is generally recommended to use a simple process. In the case of handling the strength of the ceiling frame, especially the strength of the speaker hanging position, and to make a mark, the top is made of gypsum board, the plaster molding module is used around, and the light weight is used throughout the week. A wooden geometric substrate is fine. This can be combined with a hidden three-base color lamp to form a combination of light refraction.
(5) Handle the sound insulation of each door and window
The glass door is preferably a rubber sealing strip, and double glass can be considered as a condition. 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 private rooms 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, and can also reduce the interference of sound.
(7) Handling the crosstalk and interference of the pipeline part
The interference of the air-conditioning pipe and the exhaust pipe is particularly obvious. It is necessary to handle the firmness of the pipe installation site and the sealing degree of the contact part.
