SONOROUS EMISSION

Carrying out many activities together with the use of the machine cansometimes involve physical uneasiness and weariness . For example, being

engaged with extra-working activities which require sonorous exposuresinvolves higher risks and a lower health's defence.Working conditions like, for example, the loudness of the working environmentplay an important role for the health and personal comfort.

Some factors which influence the real exposure level are:

- the period of exposure.

- the adjacent working machines

- the type and characteristics of the buildings.

Moreover, noise emission can be contained by:

- reducing the number of the machine's revolutions,- a low advancing,- a correct fastening of the piece,- a good condition of the tools.- and , above all, using the appropriate acoustic protections.

A protracted exposure over 85 dB (A) could cause health troubles.In any case, it is advisable to employ some appropriate protectionsystems (ex: casings, plugs)
