KTV compartment sound insulation
KTV rooms have certain particularity, such as small rooms, easy to cause echo, and there is a wall between rooms, which needs sound insulation. At night, we should also consider the isolation effect of the whole sound field leakage. Therefore, KTV should do a good job in acoustic design and processing.
Usually KTV sound insulation will have the following problems:
When 1.KTV is open, the indoor air noise is as high as 1 10dB, which not only has the hidden danger of disturbing the people, but also makes the rooms in KTV interfere with each other.
2. When 2.KTV is open, the sound vibrates strongly, and there will also be disturbing people and mutual interference between rooms;
3.KTV is mainly used for vocal singing, which requires high indoor sound quality. Too long reverberation time will seriously affect the use of electroacoustic system (howling and high-frequency distortion are easy to occur), and too short reverberation time will lead to the phenomenon that the sound pressure level cannot go up and the thickness is lacking.
Therefore, in view of the above possible problems, ktv sound insulation decoration generally adopts the following solutions:
First, the walls between rooms adopt composite sound insulation structure, and the audio equipment adopts elastic brackets. If the quality requirements are high, elastic floor can be used;
Second, doors and windows are generally soundproof doors and windows, or ordinary doors and windows are soundproof;
3. Carry out necessary sound absorption and diffusion treatment indoors, including the selection of sound absorption materials, the amount of sound absorption materials, the location arrangement of sound absorption materials and diffusers, etc.
Fourthly, specifically, how to construct and install the sound insulation materials of ceiling, wall, ceiling and floor. Sound insulation spraying can be recommended here. Specifically, we can see some characteristics of sound insulation spraying. I believe you will think that sound insulation spraying is the best sound insulation material for ktv in bars.
Verb (abbreviation of verb) KTV ceiling sound insulation
1, JM plant fiber shall be sprayed on the ceiling floor first;
2. Because the sound in KTV places is loud and will vibrate, it is necessary to install acoustic shock absorbers;
3. In order to achieve better sound insulation effect, it is necessary to lay a layer of 50mm sound insulation cotton under the shock absorber;
4. Finally, a layer of composite damping sound insulation board is laid to complete the sound insulation decoration of the ceiling.
Sixth, KTV wall sound insulation
1, the wall needs keel first;
2. A layer of sound insulation cotton is filled between the keel and the wall, and the specific thickness is implemented according to the plan;
3. Finally, before laying the composite damping sound insulation board, it is necessary to lay the sound insulation felt with a thickness of 2mm.
