How dangerous is noise for our hearing?

It is important to identify possible sources of noise generation to determine whether a hazard exists. Some devices may already be present to limit the effect of noise, but a detailed assessment may still be required to establish: The nature of the hazard The severity of the risk of the Involved Territories Affected personnel The risks that are identified as not properly regulated should be either removed or reduced and sufficiently controlled . The provision of ear protection shall not be considered, except as a temporary measure, until the technical controls have been thoroughly examined. These guidelines require that appropriate action be taken to reduce the effect of noise to the lowest possible level, practicable, in a different way, rather than providing ear protection. However, wherever ear protection is used, they must comply with the requirements of domestic law. It should be noted that each domestic law has different levels of acceptable noise and each organizational unit must investigate them.
