Level of acoustic pressure – Practix 280.230 G:
Equivalent level of acoustic pressure A (noise) at operator position are LAeqv=62,6 / 69,4 dB for
35 m.min-1 / 72 m.min-1 for Manual version and LAeqv= 59,5 / 65,4 dB for 35 m.min-1 / 72 m.min-1 for
Pulldown version. Mentioned values are levels of emission which doesn’t have to represent safe
levels. Factors which influence real level of acoustic pressure on machine operator are: working place
characteristics, cut material, saw band. These factors have significantly influence on acoustic pressure.
