Resumen The new European directives require machine manufacturers to reduce the noise generated by their machines to the lowest level possible, in particular by action at source. For each machine part this requires proper knowledge of noise generation mechanisms, and assessment of expected noise levels and an estimation of the contribution of the main parameters to noise emission. This data sheet covers noise emission by machine gears. It demonstrates the variety of different noise generation factors (cog contact and friction, load variation) and how the noise is transmitted through the air or mechanically from the source (the cog contact point) to the radiating surfaces (housing), illustrating the basic mechanisms often found in other types of machinery. The data sheet combines comprehension of the different mechanisms with a number of ways of reducing acoustic emission: geometric parameters, tribological factors, degrees of quality, operating conditions, etc., and clarifies the notions of action at source.
