A, how to solve the acoustic environmental problems facing the KTV entertainment apartment building
In the early construction of a building in Shenzhen, the first layer, two layer for the Cara OK Entertainment City, the upper for residential. When night fell, entertainment city to start business, people in the high-end luxury KTV rooms enjoy singing, often from individual sharp sound from the speakers, to move toward the microphone position or offset the microphone, in order to eliminate the noise in this harsh; or always hear her singing voice turbid, echo is longer, adjust the sound box amplification effect is not too obvious, these cases illustrate the room sound field distribution is not uniform, decoration materials of strong reflections on the microphone, cause howling; in addition, the reverberation time is too long, the room, the room entertainment effect effect. These adverse conditions lead to the loss of customers, later need to spend more effort to solve the problem, but the relative construction decoration processing difficulties.
On the other hand, the sound system for high power KTV rooms in the voice over 100dB (maximum acoustic energy is concentrated in low frequency vibration), through building structure, pipeline and transfer to other parts of the building. Living in the upper floors, after nightfall always hear the deep "long, long" sound, serious interference to normal life of people living (noise level exceeds the standard of city regional environmental noise: bedroom, living room at night, the noise level allowed ≤ 40 dB), especially in the elderly and the history of the crowd, in the the floor covered with thick carpet or wooden floor will be of no avail. Residential area near the building is heard to exceed the standard noise poor mood in the night, residents have to property management complaints, developers through various efforts, the moment can not be coordinated, the results should be resolved through legal proceedings, make investors and related people are subject to different economic losses and spiritual losses.
Based on the above situation, this kind of building should fully consider the acoustic environment problems in two aspects in the design of sound absorption and sound insulation, through scientific, reasonable architectural acoustics design and construction measures, the construction of acoustic material corresponding renovation, obtain good acoustic environment, realize the unity of the architectural aesthetics and function.
To solve the sound insulation problem KTV two, through structural measures and the architectural acoustics design
1, KTV room acoustical treatment (room reverberation control)
According to the room volume, surface area and other parameters, to determine the effect of reverberation chamber ideal, combined with the decoration design quality and performance intention, reasonable collocation of absorption property right, such as cloth sound absorption board, groove wooden acoustic panel, plant filamentous acoustic board and so on, are mainly arranged in the rear wall sound alignment, eliminate the adverse the influence of strong reflections on the phone; the corresponding wall such as design uses a smooth hard materials, easy to produce echoes, should also be appropriate arrangement of absorbent materials, reducing the noise defects, realize the indoor acoustic environment good, give full play to the KTV compartment acoustics system sound effect. Modernity, diversity and reflect the decorative effect.
2, indoor sound insulation construction measures
KTV rooms of bass sound is generally placed in on the ground floor, as far as possible to reduce the adverse impact sound vibrations in the building, laying on the ground vibration damping rubber is very economical and applicable scheme. Specific approach is to paste the damping rubber layer 25mm in the floor structure layer, the attention and the surrounding wall adopts elastic connection, then the carpet or other decorative surface layer.
KTV rooms around the wall and ceiling insulation measures should be adopted. The peripheral wall sealing design, windows and doors, hole, hole and other parts, the sound insulation door and window and elastic sealing material sealing. The wall inside the solid stick damping rubber or install the good performance of the insulation wall; indoor ceiling adopts elastic hanger ceiling, and set the sound absorption material
In addition, the indoor ventilation pipes are communicated with each other, the sound can be from one room to another, the noise level does not have much attenuation, the fire plant cellulose material pipes vents near the spraying a layer of 25mm, as the absorption process, can solve this problem; holes in walls, floor pipeline is also very easy to cause the air transmission, also need elastic material filling sealing.
The necessity and economy of three, KTV entertainment for acoustical engineering investment
After careful investigation, in the economic developed area of, square the cost of a standard KTV Entertainment City Decoration Engineering of up to 2000-3000 yuan /m2, part of the region and even higher. Reasonable use of acoustic material decoration, building surface square cost for 150-300 yuan / m2 (ordinary decoration materials also need to 100-200 yuan / m2), the increased cost of inadequate overall investment 5%, architectural acoustics environment suitable for, let many consumers obtain physiological sense of satisfaction, let the surrounding residents living were not affected, its price is self-evident.
Along with the improvement of China's modernization construction standards and people's environmental awareness, entertainment apartment complex has caused a lot of attention to the relevant government departments, the construction investment and construction design units, many similar buildings has to make full use of the architectural acoustics design to solve the problem of acoustic environment, and achieved good economic benefit and social benefit!
