Abstract |
Example of the conversion of a press shop with the principal objective of securing an acceptable noise environment. Several stages were required to obtain a satisfactory result. At the construction stage, it was necessary to treat the walls and ceiling accoustically. Computed projections of noise levels showed that a reduction in the amplification of a noise source by the premises by a factor of 7.5dB at 50m from the noise source was possible, but also showed that the noise level in the work place remained unacceptable, resulting in the necessity to enclose the noisiest presses. This work proceeded in 2 stages, reducing the noise level in almost all passages between machines to below 85dB(A). |
