Acoustic data of the standard machine at full load working conditions.
WARNING:
In a closed room the noise produced by a sound source reaches the listener in two different ways:
•
Directly
•
Reflected from the surrounding walls, floor, ceiling, from furniture.
With the same sound source, the noise produced in a closed room is greater than that produced
outdoors. In fact, the sound pressure level generated by the source, must be added to the one reflected
from the room. Also, the shape of the room affects the sound.
