KTV decoration materials

In KTV decoration materials, the commonly used materials are sound insulation materials, sound-absorbing materials, damping materials, etc.

KTV decorative materials in the sound insulation materials are: Jingxin sound insulation felt, gypsum board or calcium silicate board, solid brick and so on

KTV decorative materials in the sound-absorbing materials are generally more commonly used: rock wool or glass wool, perforated board, soft package, etc

KTV decorative materials in the damping materials are: shock absorber, damping ceiling rod, etc.

Different decoration materials solutions: 1. Sound insulation, sound insulation is the best way to solve "crosstalk", sound insulation should first control the sound transmission of the noise source, the speaker should not be directly hung on the wall or placed on the ground, can use elastic hook or damping pad, so that the speaker and the building elastic connection. The sound insulation of the ceiling must be done well. The keel is made on the ceiling, and the cavity of the keel is filled with sound-absorbing cotton. The following is the sound insulation material and gypsum board. Sound insulation materials must be selected with good sound insulation function. The wall can be constructed in the same way as the ceiling. If necessary, the floor and wall should be treated with sound insulation; 2. Reverberation, the right and wrong of reverberation time and the size of reverberation intensity have great influence on sound quality. If the time is long, the voice will be turbid, which will affect the clarity and intelligibility; if the reverberation time is too short, it will appear. When singing, the voice is very dry and astringent, lacking of brightness and simplicity. Reverberation time is an important acoustic characteristic of karaoke and other entertainment places. Experienced acoustic experts will skillfully use the change of decoration structure and different materials to solve the acoustic problems of sound field environment. We see in many places decoration is not used "soft bag", singing is really easy and natural.

Different decoration materials and structures of KTV private rooms will cause acoustic dyeing phenomenon. Because the sound will encounter different reflectors when it diffuses. When the reflecting interface or reflector resonates, the original sound is added with no timbre components, thus changing the sound quality of the sound, which is called sound dyeing. We should avoid sound dyeing in material selection and construction engineering. The decoration materials of KTV compartment are directly related to the sound field parameters. On the one hand, it is necessary to use materials suitable for acoustic decoration, such as mineral wool sound-absorbing board, etc. On the other hand, the sound quality of environment-friendly materials is directly related to the sound quality.

Because KTV is a public place, so fire prevention is the most important. Therefore, some fireproof KTV decoration materials must be used. Similar ceiling should use light steel keel, calcium silicate board, gypsum board. If the wall must use wood and plywood, it should be painted with fire-proof paint on the wood surface before it can be used.
