perhaps we all know that a qualified KTV
processing noise in the walls, doors, windows, floors, ceilings and
other places have to do sound insulation measures. This KTV top noise is
often easy to be ignored. Thus caused the noise on the residents
upstairs. So the sound KTV ceiling is very important, must not be
overlooked. KTV smallpox sound insulation problem by making the sound
insulation ceiling can solve the impact sound. A crash is due to hit the
floor slab vibration source, vibration and impact, and the steel
structure housing the connection and communication, then the vibration
structure to the space radiation receiving sound can form sound air to
the receiver. Therefore, there are three main impact sound isolation
measures: one is the vibration source collision induced attenuation of
the floor, through the source of vibration control and vibration
isolation measures to achieve, can also be laid on the floor in the
elastic layer to reach the surface. Two is the spread of the vibration
of the vibration in the floor structure, which can usually be in the
floor and load-bearing structure of the elastic cushion between the
settings to achieve, this approach is often referred to as floating
floor". The three is to separate the vibration structure receiving space
Bureau air sound, this is usually in the floor under the top of the KTV
sound insulation to solve. The main design method of noise protection is
the most effective and clear sound source characteristics, and then use
the acoustic knowledge to determine the design of material and
structure, and to intervene early in the decoration, can be prepared
against want a multiplier effect. Sound insulation design of the main
aspects of bars, KTV, disco Entertainment: 1 to enhance the sound
insulation wall first solve the wall itself and not closed, holes and
other problems; according to the law of quality, quality usually
increases the sound insulation wall half will increase the amount of
6dB, but the sound insulation materials and reasonable structure can be
changed, can be used magnesite honeycomb panels, low frequency sound
insulation board insulation magnesite plate, the wall insulation
performance get greatly improved. 2 to solve the problem of sound
leakage of the door and the window as most KTV rooms are the ordinary
door or door in the KTV room roolls, up to more than 105dB under high
noise environment, sound insulation is clearly not enough, the solution
can be used to design the soundproof door or double doors, the formation
of "sound gate" across the sound structure significant effect. Sound
insulation design of 3 smallpox essential high noise bar, KTV is to
spread from all sides, also called random incident, and some speakers
are hanging on the ceiling in the ceiling, so strengthen the soundproof
and sound-absorbing is essential, can take the double ceiling, spraying
K-18 plant cellulose materials in the ceiling, or the laying of other
insulation material has a good effect. Sound damping is very important
to the 4 ground laying damping sound insulation mat, sound insulation
floor, vibration isolator and other problems of the 5 speakers should be
produced by vibration strengthen the importance of sound, whether it is
a frequent speaker or multi channel system, low frequency sound must
exist, so we must do a good vibration damping measures, the general use
of vibration damping hook Taiwan, vibration method. 6, other, air
conditioning and ventilation noise problem is best able to use muffler
processing. The self vibration of the air conditioner pipeline can be
sprayed with K-18 plant cellulose, or damping sound insulation felt for
a comprehensive treatment. The top of the KTV sound scheme by using the
elastic ceiling, with the original structure without any steel
connections, prevent sound hit the building the original floor structure
is transmitted to the upper room, the design of sound insulation for
45dB attenuation, acoustic resonance frequency is less than or equal to
31Hz
Elastic sound insulation as close to the ceiling, to ensure KTV rooms is
not affected by noise pollution. The length of the design boom is 300mm,
if possible, KTV top noise material can be based on the construction
site situation and then short. Local boom length (such as the case of
cross beam, ventilation pipe, water supply and drainage pipeline, etc.)
need to be adjusted according to the actual height. The elastic
suspended ceiling is located on the top of the fire sprinkler pipe and
the air conditioning duct, and the suspension of the lighting
arrangement, ventilation, air conditioning ducts and the prefabricated
parts of the local decoration must be separated from the original floor.
In order to ensure the sound insulation effect, the sound insulation
ceiling inner cable, the fire pipe penetrates the sound insulation
ceiling layer, must use the sealant to seal the processing, prevents the
leakage sound. Do not have to open the large hole of lighting lamps and
lanterns. Air conditioning air outlet. Do not damage the KTV ceiling
seal, this is conducive to increase the sound insulation effect. Noise
ceilings can be made in the form of a ceiling. Other common materials
available ceiling lamps, can open a big hole, and the air outlet. The
inorganic fiber in KTV insulation engineering ceiling sprayed on the
1st-acoustics coating material can form a dense protective film on the
sound insulation board outside, so it can greatly reduce the noise
pollution. In addition, there is also a sense of artistic level. Can
make the top of the KTV become beautiful. KTV sound insulation is very
important, specific to the top of the sound can be modified according to
specific. Finally, I wish to be engaged in KTV's friends in one fell
swoop success..
