Maximum noise levels often occur as the workpiece makes contact with the bottom first head. Noise levels then fall off as the feed system takes hold of the timber. Doubling the timber width is likely to increase feed position noise levels by 6 dB. The use of feed attachments can reduce infeed noise levels by 5dB, by damping out the vibration.

To begin, noise levels must be determined at the loions from which the complaints arise. Once levels have been determined, the next step is to apply acceptable noise level criteria to each loion and thus to determine the required noise reductions, generally as a function of octave or onethird octave frequency bands (see chapter 1). Once the noise levels have been measured and the ...
