2.4 Noise

The noise level produced is checked on all the models of machines produced by FERRI srl.
The noise values indicated are emission levels and do not necessarily represent safe operational levels.
Despite the existence of a relationship between emission levels and exposure levels, it cannot be accurately used to establish
whether further precautions are required or not.
The factors which determine the exposure level which the work force is subject to, include the duration of exposure, the characte-
ristics of the work environment and other sources of noise (number of machines, nearby activities etc).
Furthermore, the permitted exposure levels can vary from one country to another.
However, the information on the level of noise produced by the machine will help the machine user to assess the dangers and
risks.
The noise level measured at the operator's ear is between 75 dB and 78,5 dB with the cab
closed and between 82.9 and 84.4 dB with the rear glass of the cab open.
The acoustic power level is LWA 102,5. At a noise level perceived by the ear higher than 85
dB it is recommended to use personal protection equipment.
Noise over 85dB over an exended period of time will cause severe hearing loss.
Noise over 90dB adjacent to the Operator over an extended period of time will cause per-
manent or total hearing loss.
According to the data measured in the various positions examined, in the absence of a soun-
dproofed cab it is recommended to use personal hearing protection equipment.
