Description

The basic insulation between two rooms is the difference in the levels of acoustic pressure measured in the transmitting room and in the receiving room. This includes all direct and indirect noises, and is expressed in dB (A). The transmitted noise is known as ‘Rose’ (a constant level for all frequencies), and as ‘Route’ noise (taking account of the sensitivity of the ear to different frequencies) The sound value of a wall allows evaluation of the direct transmission between one room and another. The value of Acoustiply panels between 2 rooms has been calculated in dB (A) for ‘Rose’ noise transmission and ‘route’ noise transmission. The results obtained varied from 32 to 34dB (A) in R ‘Rose’ and from 28 to 32dB (A) in R ‘Route’. It should be noted that these figures correspond to a direct transmission and, in practice, should be lowered by d dB to take account of lateral transmissions. These results compared with plywood & brick demonstrate that Acoustiply has a very good acoustic ratio.
