KTV Architecture Acoustic Design Karaoke Hall Interior Decoration Design​



1. Overview of architectural acoustic design of KTV and other entertainment venues


Classification of KTV places

A. Volume format KTV

Friends gathering, family reunion, classmate party, birthday celebration. The democratization of consumption.

B. Senior entertainment club

Luxurious decoration, suitable for business entertainment, pay attention to privacy. High consumption.

C. nightclub

The design area of the small private room is 8~11 square meters, the design area of the medium private room is 15~18 square meters, the large private room is 24~30 square meters, and the extra large private room is more than 55 square meters.

my country is the country with the most karaoke in the world, and its decoration styles are different, but the problem of poor acoustic effect is common. No matter how luxurious the interior decoration of the KTV is and how advanced the sound system is, when people go to sing, they will find it very difficult to sing, or there will be sound staining. In some places, the crosstalk is serious, and some KTVs also complain continuously because the noise emitted affects the normal life of nearby residents and cannot operate normally. In order to ensure the normal operation of KTV, the acoustic effect of KTV cannot only rely on high-end sound system, and it is not practical. It is also necessary to create an excellent acoustic environment for a good sound system, so that the sound level can be brought into full play. This requires architectural acoustic design, and it must be penetrated into the decoration and decoration of KTV from beginning to end.

2. Project characteristics and acoustic problems of architectural acoustic design of KTV and other entertainment venues


1. Sound quality problem

(1) The reception room and waiting room have a large capacity. Without any architectural acoustic decoration, the reverberation time is too long, the sound is muddy, and the clarity is low, which affects the normal conversation between the guests and the reception staff.

(2) The shape of the private room is regular and square, and the room capacity is small, which is prone to sound coloration, resonance, resonance, etc.

(3) The shape of the private room is curved and concave, which is easy to produce sound focus.

(4) The reverberation time of the private room is too long, coupled with the defects of the equipment itself, it is easy to produce howling. At the same time, too long reverberation time affects the clarity of the singer's hearing.

2. Noise

(1) The sound insulation performance of the partition wall between private rooms is poor, and crosstalk occurs between private rooms.

(2) The sound of impact on the ground is loud, and the noise emitted by KTV affects the normal life and work of nearby residents.

(3) Equipment noise, central air-conditioning system, and ventilation system are too noisy.


3. Sound quality design of architectural acoustic design of KTV and other entertainment places

1. The walls and ceilings of the reception hall and waiting hall are reasonably arranged with sound-absorbing materials and sound-absorbing ceilings according to the size requirements of the reverberation time. See CAD drawings for specific specifications, areas and installation methods of sound-absorbing walls and ceilings.

2. The walls and ceilings in the private rooms are reasonably arranged with sound-absorbing materials according to the calculated reverberation time. The small private rooms are mainly equipped with sound-absorbing structures on the back wall and the opposite wall of the audio equipment and video. Medium private rooms, large private rooms and extra large private rooms should reasonably increase the material area according to the reverberation time requirements. In order to reduce costs, a sound-absorbing ceiling can be installed. Care should be taken to avoid making a "cavity" structure.

3. The placement of furniture and other decorative designs should be considered to be conducive to the diffusion of the sound field. For example, the distance between the audio equipment and the singer should be far, which is beneficial to the diffusion of the sound field.

4. The deviation of the test value of the sound pressure level of the sound field at each point of the private room is less than 2dB.

5. Set up an independent bar counter or private area in the sound shadow area to avoid the impact of the sound shadow area on other functional areas.


4. Sound insulation and noise control in architectural acoustic design of KTV and other entertainment venues

(1) Sound insulation of the wall: sound insulation treatment should be done between the hall and the private room, and between the private room and the private room. First of all, the economical and practical is the 2/4 red brick wall, the partition wall must be built to the top, and the second is the sound insulation wall, using light steel keel gypsum board or sound insulation and fireproof board.

(2) When the wall needs to be routed through ventilation ducts or other wiring, holes should be drilled through, and the lines should be sealed to avoid crosstalk.

(3) Ground sound insulation: The air noise in the room will be transmitted to the downstairs and the structure through vibration, which can be solved by leveling the ground, spreading sound insulation materials, and installing the floor.

(4) Ceiling sound insulation: On the basis of the original floor, make a light steel keel ceiling, form a cavity outside and fill it with sound-absorbing materials, and use double-layer gypsum boards to make a light-weight ceiling under the sound-absorbing materials.

(5) Choose exhaust and air conditioning systems with low-frequency sounds, power amplifiers, microphones and audio systems with low impedance damping coefficients. Reduce background noise.

(6) Carry out necessary noise reduction, sound insulation and vibration reduction treatment for the ventilation system and central air-conditioning system.

(7) Other structures such as power distribution rooms, machine rooms, and cooling towers must be sound-insulated and vibration-reduced.

(8) Doors and windows that communicate with the outside world must be sound-insulated, and doors and windows must be sealed without gaps.


5.Material requirements


1. The ceiling materials of halls and private rooms should adopt grade A decoration materials, and the wall and floor materials should not be lower than grade B1.

2. The ceiling materials in the evacuation passages and corridors should adopt grade A decoration materials, and the wall and floor materials should not be lower than grade B1.

3. The keel materials used for the ceiling and wall decoration of halls and private rooms shall be Class A materials.

4. The fire resistance limit of the partition wall is not less than 2.0h, and the fire resistance limit of the floor is not less than 1.5h.

5. The number of evacuation doors should be determined by calculation, and should not be less than 2. And should not be less than 0.90m. Class A fire doors should be used.

6. There is no glass fiber dust pollution, which meets the requirements of environmental protection. The amount of formaldehyde released reaches the standard above E1 level.

6. Five-step service process

01. Understand customer needs
The first step is to understand the customer's needs (data provided: on-site video, on-site accurate CAD drawings, the style that the customer likes)
02. Plane layout planning
The second step is the layout planning, after the modification is confirmed (charge: deposit for design scheme)
03. Scheme Design Customization
The third step is to customize the scheme design (production of renderings and simulation software), and confirm the modification (fee: final payment for design scheme & deposit for construction design scheme)
04. Construction design drawing
The fourth step is to complete the professional docking of machinery, equipment, fire protection, water and electricity, etc., and complete the drawing of construction drawings (charge: final payment for construction scheme design & construction deposit)
05. Construction site follow-up
The fifth step is to follow up on the construction site and actually modify and adjust - the construction is completed.
