　　KTV Architectural Acoustics Design

　　The KTV architectural acoustics we are talking about here has a certain scope and limitation. Generally speaking, KTV architectural acoustics can be divided into two parts: one is "sound insulation" processing; the other is "sound field" processing. The "sound insulation" processing is aimed at how to deal with "noise"; and the "sound field" processing is aimed at how to make the sound system play a better effect.

　　Soundproofing

　　We know that most of the KTV industry is an entertainment venue that operates at night. In the dead of night, a little noise can travel far. Our country has high requirements for noise restrictions in cities at night, mainly to prevent disturbing people. But in fact, most of the entertainment venues currently fail to meet the noise control standards required by the state. This is because most entertainment venues do not pay attention to the sound construction. In addition, in addition to dealing with external environmental noise, the sound between boxes and boxes in the entertainment venue cannot interfere with each other. For the sound insulation treatment in the KTV box, you can pay attention to the following points:

　　1. Wall sound insulation: of course, thick concrete walls and brick walls have better sound insulation effects, but now many KTV entertainment venues use wood or other decorative materials to make walls, and the sound insulation effect of such walls is relatively poor. For walls, affected by the structure of the building, it is impossible for general entertainment venues to make major adjustments to the original building walls. If conditions and necessary, you can build a room within a room, that is, build another layer of walls, but the current Party A The boss would rather go for a walk with the noise exceeding the standard, and he doesn't want to be so troublesome, so he just added some more suitable sound insulation materials to the walls.

　　2. Sound insulation of doors and windows: In KTV sound engineering, the windows are generally sealed in KTV boxes, which can play the role of sound insulation, safety and privacy protection. For KTV boxes with windows, double-layer soundproof glass windows can be considered. Or configure thicker curtains; similarly, the sound insulation effect of KTV doors should be better. Now some professional sound insulation doors have sound insulation materials inside, and sealing rubber edges will also be used for windows and doors to further sound insulation.

　　3. Ground ceiling sound insulation: On the one hand, the sound insulation of the ceiling is to prevent the noise from being transmitted to the upper floor. This is mainly to use the ceiling sound insulation, if necessary, add suitable sound insulation materials to the ceiling; on the other hand, it is to prevent the sound from passing to the adjacent box middle. In order to save cost, time and convenience, some entertainment places have adopted the method of hanging the ceiling first and then the partition wall, which is very detrimental to sound insulation. Therefore, the reasonable construction sequence is to construct the pipeline first, then build the wall and seal the wall. At the same time, we must pay attention to the shock resistance of lamps and ventilation windows embedded in the ceiling.

　　4. Sound insulation of pipeline system: For those fire pipes, sewer pipes, etc., if the sound insulation is not good, the noise will continue along the pipeline. This is the same as the principle of railway tracks, because the sound transmission speed of metal and solid is faster than that of air. Far. For the sound insulation of the pipeline, we can hide the pipeline, add sound insulation materials to the surface of the pipeline, etc., and try to keep the speakers away from the pipeline.

　　5. Sound insulation of the ventilation system: The ventilation system mainly refers to the air conditioning pipes and exhaust systems. The pipes of the central air conditioning are made more tightly due to the need for "heat insulation", which is also very good for sound insulation; KTV audio In the project, many KTV boxes directly embedded the exhaust fan in the wall, which has a very poor sound insulation effect, so the ducted exhaust method can be used.

　　6. Sound insulation of system wiring: When we carry out system wiring construction, it is inevitable that we have to pass through some walls or ceilings. At this time, we should pay attention to the appropriate perforation. After the pipeline is laid, Party A can notify the mason or painter to use cement or sludge and other materials to fill the holes around the pipeline. Doing so is great for soundproofing. Of course, the above-mentioned sound insulation treatments are all aimed at architectural acoustics, and we should also pay special attention to the source of sound, the "speaker". When hanging the speaker, you can use shock absorbers, etc., and pay attention to hanging it on a suitable wall; yes For floor-standing speakers or subwoofers, you can use speaker brackets or shock absorbers to reduce the vibration of the speakers.
