Abstract In this study, measurements were made of the directivity of noise emitted by three types of woodworking machines using a simplified acoustic intensity method enabling quick determinations to be made inside workshops. These measurements showed that the directivity of the machines studied was relatively low. Next, the influence of the directivity of these noisy machines on the exposure of workers was evaluated in a woodworking shop. Simulations showed that characteristics of the premises had little influence on noise source variability as a function of source directivity. The key factors influencing exposure were the position of the worker and his or her distance from the machine.
