Calcium silicate sound - absorbing panels with what inspection lot
Sound-absorbing board is porous multi-slit plate, basically ventilation. Most of the things can be directly through the plate to see the other side of the board thing. Mainly from the sound-absorbing effect, that is, to weaken a certain frequency in the board side of the amount of reflection. There is little sound-absorbing board directly to do the partition, so the sound-absorbing panels are generally not used to deal with the sound problems on both sides of the board, only dealing with unilateral sound field.
Silicon calcium board is a compact board, basically airtight. Relative to the sound-absorbing panels heavier and harder. Is a sealed plate. Mainly from the sound effects. That is to stop the sound on both sides of the space in the spread of space.
According to the use, the state has the best reverberation timetable for all kinds of halls, and the reverberation time of the audible field can be checked by the reverberation. With ordinary fire test whether the fire standards.
