Abstract By considering the 90 dB(A) legal daily exposure limit for noise, it is estimated that 400,000 Quebec workers are at risk of hearing impairment. Although the enclosing of noisy machines is favoured for reducing noise exposure, the effectiveness of these isolating enclosures may be insufficient due to a lack of appropriate acoustical dimensioning. This report describes the development of acoustical design support software integrating certain mechanical and geometric complexities. This tool should allow enclosure designers to better dimension their products by estimating their effectiveness beforehand.
