Gypsum board is a kind of material which is made of building gypsum as
main raw material. It is a light weight, high strength, thin thickness,
easy processing, as well as sound insulation and fire insulation and
better performance of building materials, is currently focused on the
development of one of the new type of light.
Gypsum board has been widely used in residential, office buildings,
shops, hotels and industrial factories and other buildings within the
walls, wall panels (instead of plastering layer), ceiling panels, floor
base plate, and various decorative plate.
1 sound-absorbing board is sound-absorbing noise reducing effect of
materials with the fingerboard shape, mainly used in theaters, concert
halls, museums, galleries, libraries, galleries, auction hall, room,
gymnasium, hall, multi-function hall, hotel lobby, hospitals, shopping
malls, schools, piano room, conference room, studio and the studio, KTV
rooms, bars, industrial workshop, computer room, noise reduction and
other high requirements and high-grade decoration places on the acoustic
environment.
Then the perforated gypsum board and wooden sound-absorbing panels and
what is the difference?
Perforated gypsum board with cylindrical hole through the front and back
of the gypsum board, with breathable back coating material of and can
absorb the incident sound absorption materials and paste in the back
group of gypsum board.
The absorption mechanism is material within a large number of tiny
connected pores, these pores can be further along the acoustic material,
energy will be transformed into heat effect and friction materials.
The sound absorption coefficient of the porous sound absorption material
is gradually increasing with the increase of the frequency, which means
that the low frequency absorption has no high frequency absorption.
2 boards made of ceiling or wall panels, etc., the sound absorption
mechanism of this structure is the thin plate resonance sound
absorption.
At the resonance frequency, due to the severe vibration of thin plate
and a large number of sound.
The resonance absorption of the thin plate is mostly in the low
frequency and has a better sound absorption performance.
3 to sum up: one is the absorption of high frequency, one is the
absorption of low frequency.
