A lot of times we live too much noise,
and the noise makes our mood and the efficiency of doing things are
greatly affected. Especially in the vicinity of the road residents, so,
noise walls will be used in the side of the road side of the wall
structure, noise walls, also known as the sound barrier. Another place
is the soundproof walls or recording studio. Today we will come to
understand the noise insulation wall construction technology, the
principle of the wall and look at the construction plans. Acoustic
principle, soundproof wall principle is to soundproof wall between the
original wall and soundproof walls have a cavity, or a buffer layer, so
that the noise through space, distance decreases, then the noise through
the porous sound-absorbing material into heat energy, so as to further
reduce the effect of noise, so do also have insulation. The principle of
acoustic sound insulation wall is in between the original wall and
soundproof walls have a cavity, or a buffer layer, so that the noise
through space, distance decreases, then the noise through the porous
sound-absorbing material into heat energy, so as to further reduce the
effect of noise, so do also have insulation. Two, sound insulation wall
construction technology 1, suitable for industrial plants and auxiliary
buildings have high noise (ventilation room, refrigeration room, air
conditioning room, diesel generator room, printing workshop etc.).
Applicable to the requirements of the acoustic environment relatively
high hall (hall, conference hall, lecture hall, theater, gymnasium,
studio, recording studio, studio etc.). The size of openings: width of
900 ~ 3300, 2100 ~ 3600 and high. Sound insulation: when using no
threshold approach, its vibration volume is less than or equal to 30dB;
when using a threshold approach, its vibration volume less than 40dB.
The steel fireproof and sound insulation door is suitable for the place
where there are sound insulation and fire prevention requirements. 2,
the inside of the door leaf of the door leaf material filling material
and the thickness, determined by the manufacturer according to the sound
insulation and fire protection requirements. Glass cloth or cotton
fibers with intermediate glass wool products general leaf in filling the
volume density control in 80 ~ 100Kg/m3. Frame and panel sound
insulation door is divided into six types: a type of steel frame,
cold-rolled steel panel (no door); B type steel frame, cold-rolled steel
panel (no door); C type light steel keel frame, color steel panel; D
type light steel keel frame, cold-rolled steel plate; E type light steel
keel frame, galvanized steel sheet panel; F type wooden frame, soft
leather bag panel; E type fireproof sound insulation door, design in
project design and selection, should indicate the fire rating of the
door and the door leaf packing material requirements. When using the
singing door selection table, the design requirements of the design
should be based on the type of material code plus. Seal: use three EPDM
rubber products. Three, sound insulation wall construction of sound
insulation wall thickness is determined by the size of the noise source,
the noise source is a sound insulation wall thickness will increase,
usually about 5-10 centimeters, adding soundproof walls will sacrifice a
part of the interior area, structure of soundproof wall is generally in
between the original wall and light steel keel frame for 2-5 cm the
sound insulation material is filled in the cavity, light steel keel
frame, and then covered with a layer of gypsum board with a layer of
insulation material applied to the gypsum board, so that the entire
surface of the soundproof wall thickness in 5-10 cm. Soundproof wall
thickness is determined by the size of the noise source, the noise
source is a sound insulation wall thickness will increase, usually about
5-10 centimeters, adding soundproof walls will sacrifice a part of the
interior area, structure of soundproof wall is generally in between the
original wall and light steel keel frame set aside 2-5 cm cavity, the
sound insulation material is filled in light steel keel frame, and then
covered with a layer of gypsum board with a layer of insulation material
applied to the gypsum board, so that the entire surface of the
soundproof wall thickness in 5-10 cm..
