KTV sound-absorbing construction
process ktv sound-absorbing construction program today
KTV sound quality of the construction process has been related to
whether a KTV long-term profitability. Because the KTV
general construction in commercial, residential residential building in
the low-rise, private rooms in the high-power
sound system produced by the sound pressure up to 100dB above (the
largest acoustic energy is mainly concentrated in the
low-frequency part), through building structures, pipelines, etc.
Vibration to other parts of the whole building, or
through the ground, air transmission to the surrounding buildings.
Residents living in the building floor or the
surrounding residents are often noise interference (especially in the
elderly and related medical history of the crowd),
have to the government environmental protection department or property
management complaints, take remedial measures are
often outweigh the benefits, so that investors and related The crowd is
subject to varying degrees of economic loss and
mental loss. So a good KTV
Decoration noise construction program can be seen is very important. KTV
private rooms with luxurious modern decoration is
very strong, but less concerned about KTV
Sound absorption construction process, the reverberation time control
room and trembling echo sound defects are not
perfect treatment, there will be sound and sound mixed erosion,
whistling "flying wheat" and other phenomena, affecting
the normal sound system, adjust the amplifier, speakers, Microphone and
other equipment, the effect is not obvious,
greatly reducing the sound quality of the entire field, the impact of
the reputation of the source of a larger evaluation.
Based on the above, KTV rooms in the early construction should be fully
considered KTV
Sound insulation and sound insulation in the construction of the two
aspects of architectural acoustics, through
scientific and reasonable acoustic design and construction measures, the
use of the corresponding architectural acoustics
materials for decoration, neither increase the cost of investment, but
also get good The acoustic environment, to achieve
the perfect combination of architectural aesthetics and the use of
functions. Specific KTV noise isolation and sound

likely to cause sound transmission, also need to fill
with elastic material closure, such as in the convergence of the
inorganic fiber coating on the K-18. Production and
installation of dense quality, good sealing around the thick wooden
doors, to prevent the sound of rumor. KTV box
business, mainly in the amplifier, subwoofer sound normally open, the
indoor sound pressure level is high, generally 95 -
105 dB (noise level) (A), and low-frequency components of 40 - 160Hz
low-frequency noise will likely be higher, reaching
110 - 118 dB, and its transmission will be shock wave, the way the
spread of solid vibration Out, high noise often
produces tinnitus, boredom and so is like. As the floor decay is slow,
the indoor noise impact on the upstairs household
will also change periodically. If it is not processed, it will cause
serious noise pollution in the neighboring areas such
as the surrounding area and the upper and lower floors. The difficulty
of noise control is mainly reflected in the
isolation of low-frequency noise, so low-frequency noise control
measures should be given priority to consider. Noise,
mainly through the floor, walls, pipes, concrete columns and other fixed
structure to produce transmission. The main air
through the doors and windows to spread; low-frequency, vibration mainly
through the floor, walls, Noise control measures
Implementation measures: based on experience, acoustic design, noise
reduction treatment should be involved from the early
decoration, before receiving the desired acoustic effect. In the
implementation of the decoration, the allocation of audio
equipment in the early stage, you can carry out the implementation of
vibration and noise reduction project to ensure that
the KTV box after the completion of the noise, sound-absorbing KTV noise
control solutions: smallpox sound insulation,
sound treatment KTV rooms indoor ceiling Installation of double-layer
insulation ceiling (total thickness of about 500mm),
each layer of sound insulation ceiling with different settings, in order
to achieve broadband sound insulation, while
sound insulation ceiling damping sound insulation material to meet the
low-frequency noise to enhance the cut off, Ceiling
and between the top of the set of sound-absorbing material,
sound-absorbing material should be set with the sound
insulation ceiling handle to prevent sound shock wave caused by sound
insulation ceiling vibration and stimulate the
sound-absorbing material to reduce jitter noise reduction effect.
Composite damping sound insulation wall vibration
treatment KTV room interior wall need to do damping sound insulation
wall (thickness of about 150mm), sound insulation
wall and the existing civil wall to form a wall of sound barrier, which
Layer damping sound insulation wall, the need to
focus on low-frequency sound insulation and acoustic shock wave effects,
while the inner wall of the damping sound
insulation and sound insulation between the walls need to strengthen the
overall treatment to enhance the overall sound
insulation. KTV private rooms, some of the load-bearing cement column
highlights, will also be a more serious solid
transmission of the local one, therefore, for the structural column must
also be damping sound insulation treatment, the
treatment principle and wall processing is basically similar . Floating
sound insulation treatment: In order to block
vibration and shock waves caused by solid sound, the floor must be
suspended flooring, flooring set the need to consider
the overall damping treatment, the natural frequency of the ground
damping layer, load-bearing capacity Doors and windows
are the weak link of sound insulation treatment, we must pay attention
to this, can be part of the room windows (windows
do not ask for much of the Room) to block, all into the civil structure
of the brick wall, and for such as luxury rooms,
presidential rooms and other high requirements of the room can be added
to a layer of soundproof glass windows to form a
double soundproof windows, the same can To achieve sound insulation
requirements and lighting and ventilation
requirements. Door of the higher noise requirements, the door handle is
mainly the front door and back door, which can be
set up two doors front door, the formation of the sound gate.Provide the
installation of high-grade acoustic doors to
reduce the acoustic shock Sound insulation and noise reduction design of
the air conditioning system: KTV for the crowded
gathering area, to maintain good ventilation is essential, but there
will still be noise transmission and Too high
problem, because the air conditioning running, KTV indoor sound,
speaking and other sounds can be spread through the air

can take muffler conversion Access, access, etc. to achieve the desired
effect of the muffler.The air conditioning itself
air-conditioning host noise, airflow sound, and the resulting pipe
resonance and other muffler processing should be
related to the procurement, suppliers together to To ensure that the KTV
operating noise reduction equipment (speakers)
vibration damping treatment: the Department referred to the vibration
treatment is mainly for this one, because the
subwoofer and full-frequency sound has a strong vibration, the vibration
will be directly The impact of the top or the
ground connected to stimulate the top vibration, ground vibration
effect, therefore, must be done to deal with
vibration.According to requirements, each KTV rooms all the audio
equipment (mainly full-range audio and subwoofer)
Vibration damping must be done, such as the ground placed to set the
shock absorber, the need to set the damping of the
elastic damping hanger which sound hoisting way, furnishings also need
to give acoustic considerations to enhance the
overall noise reduction effect. Vibration isolation equipment design,
the natural frequency needs to be designed according
to the characteristics of sound. Other processing; vibration isolation

insulation treatment facilities at the same time, other factors may also
affect the overall , Such as through the ceiling
of the pipe, sewer, etc. are likely to greatly reduce the noise
reduction effect, therefore, in the design and
construction process must pay attention to these issues, and be
addressed at the same time, To avoid the project due to
other causes of adverse effects. Sound quality defects processing: This
part will be combined with interior decoration to
consider, after the completion of soundproofing construction, the
decoration must be post-review, to avoid sound defects,
and affect the indoor sound effects First of all, should be involved in
the implementation of the first, that is, the
first implementation of the sound insulation construction program
mentioned in the sound insulation treatment measures,
the interior and then renovated, while the decoration must be arranged
for professionals to conduct the necessary details
of the inspection , To avoid the use of sound effects when decoration

according to national standards. Upstairs and the
surrounding residents are not affected, to achieve better economic and
social effects.
KTV sound insulation construction process is based on different KTV
rooms do small changes, to find the most suitable for
their own KTV sound insulation program.
