2.9 Noise
The machine was designed and manufactured in such a way as to reduce at source the machine noise level.
Obviously, sound pressure varies in relation to the type of blade, its wear status and the material to be cut; hence, we have made a series of
measurements using different types of blades and different materials, both indoors and outdoors.
Measurements made in the operator position on a similar machine have provided the following values, where:
The weighted continuous equivalent sound pressure level A1 [LAeq = dB(A)] Outdoor measurements

Hollow
Double-firing
Porcelain

Instrument used
Bruel & Kjaer mod. 2221 class 1
Reference standard
DIN 45635
The use of the machine is only allowed provided that suitable hearing protection is ensured. The employer shall hence compulsorily provide the
operators with personal protection equipment (earphones, plugs).
