Abstract An analytical model is used to simulate the impact of noise control measures for reducing daily noise exposure levels on noisy machines in the design of workstations and workplaces and the acoustics of industrial halls. Validated by real data, this model is applied to the simulation of several occupational noise exposure situations and quantifying predictable acoustic improvements when various noise reduction actions based on technical and organisational means are implemented. Results are discussed in relation to workstation and type of exposure situation. They highlight lines of action to be favoured at workshop design stage to achieve significant reductions in noise exposure and emphasise the advantage of acting at source through actions to curtail machine-emitted noise.
