Noise levels
Measurements were made in a Hypertherm engineering laboratory, with other equipment operating nearby, in
accordance with Hypertherm instruction ESI-034. These measurements only provide a general indication of the noise
produced by the plasma system. Sound measurements should be taken after installation to determine the specific
noise levels at the site. Measurements were taken at distances of 1 m, 2 m, 3 m, and 5 m (straight-line distance)
from the center of the arc. An operator standing at the CNC controller would be approximately 1 m from the arc. All
measurements were made with a Bruel & Kjaer sound meter mounted on a tripod at a height of 336.55 mm (13.25 inch)
above the center of the arc.
