A complete family KTV is composed of three parts: equipment, decoration and acoustic environment. It can be divided into a song system, a sound system, a video system decoration and an acoustic environment. The room can be classified as an acoustic decoration without acoustic treatment. Echo, noise, distortion, poor sound and other issues, a set of high-quality home digital video equipment in an unsuitable environment, the sound effect is not as good as a set of quality home digital cinema equipment in a suitable environment. Therefore, the overall acoustic environment decoration and the placement of the equipment play a decisive role in the effect of the family KTV. How to do acoustic treatment? 1. Â Â Â Â Â Â In the selection of the room, the irregular chamber shape is used to facilitate the sound diffusion of the room, so that the short-term vibration frequency of the low-frequency region is dense, thereby avoiding distortion . 2. Â Â Â Â Â Â In the family KTV , if the acoustic treatment is improper, it is easy to produce obvious standing wave, tremor echo and other defects. In addition to selecting the appropriate room ratio, it can be combined with the indoor sound absorption structure to provide a diffusing structure or a sound absorbing diffusion structure that integrates sound absorption and diffusion, such as a perforated spherical body and a polygonal body. 3. Â Â Â Â Â Â The determination of the sound insulation of the room needs to be determined according to the noise condition of the surrounding environment. Includes both outdoor noise and noise conditions in adjacent rooms. [The sound insulation of general household KTV is 45dB (A)]. 4. Â Â Â Â Â Â In order to effectively isolate the interference of noise and vibration to others. At present, the "floating" structure is widely used. No matter what kind of "floating" structure, it must be constructed in accordance with the prescribed design procedures to ensure the effect of vibration isolation and noise reduction. The construction of "floating" structure can be divided into steel springs and partitions. The vibration material "floating" device and the vibration isolation pad "floating" light structure. The currently used gypsum board/calcium silicate board light wall has a sound insulation of 1 gypsum board/calcium silicate board filled with centrifugal glass wool/rock wool sound insulation of 40.0dB 2 gypsum board/calcium silicate board hollow 100mm sound insulation It is 45.0 dB. 5. Â Â Â Â Â Â Finally, the acoustic structure and the art of decoration should be integrated, and there is no trace of acoustics, but there are acoustic effects.
