KTV sound insulation is to solve the
"crosstalk" the best way, in theory, the higher the hardness of KTV
insulation
materials, the better the noise effect. The most common decoration
method is light steel keel gypsum board partition wall,
although the middle of the sound-absorbing cotton, but because of the
quality is not enough, poor sound insulation.
Beijing KTV most of these are decorated with this method, poor sound
insulation. Beijing Fangzhuang area is a decoration
of the KTV also used this decoration method, the effect of the test
audio equipment crosstalk serious phenomenon,
investors can not only employ the acoustic experts to study the modified
program, could have been opened only a few days
ago , The time delay to investors caused incalculable economic losses.
It is recommended that those who are ready to
decorate karaoke OK entertainment venues must be considered before the
decoration of the room noise problem. Then KTV
noise walls should be used what material is best? KTV sound economical
and practical choice is 2/4 red brick walls, cement
walls on both sides. This partition wall must be piled to the top, you
need to take the ventilation ducts or other wiring
when the hole through, you should pay attention to the pipeline sealing
problem, otherwise the same can cause crosstalk
phenomenon. Followed by KTV soundproof wall panels, this material is a
professional sound insulation material, both sides
of the metal plate is the role of the middle of the foam plastic, the
greater the thickness of the wall insulation effect
is better. Some places due to the weight of the problem, can not use
brick or other wall method, can only use light steel
keel gypsum board approach, our proposal is in the gypsum board outside
with a layer of relatively high hardness cement
board, This cement board and the appearance of the same gypsum board
(size is almost the same), but the hardness is much
higher than the gypsum board, is a good sound insulation material, it
should be noted that the construction process
problems, especially the gap must be sealed. Sound insulation effect of
the test method is a room in the normal delivery
of music, one meter in the doorway to measure the degree of attenuation
of the sound, for example, the room sound pressure
level is 90dB, a meter outside the room measured sound pressure level is
60dB, said Sound insulation 30dB.
