Title In-cab noise reduction on an air-rotary drill rig
Bibliographic information May-June 2007, Vol.55, No.3, p.294-310. Illus. 11 ref.
Abstract A recent investigation revealed that noise levels in cabs of compressed air rotary drill rigs often exceed 85 dB(A). The National Institute for Occupational Safety and Health (NIOSH) studied the in-cab sound levels of one such rig. Preliminary tests were conducted in a controlled environment using accelerometers and microphones with spectral analysis to identify the dominant noise sources. Field tests were then performed in a production environment to evaluate noise controls to reduce in-cab sound levels. It was found that hydraulic noise suppressors reduce the structure-borne noise. Together with enhanced soundproofing, these measures reduced sound levels by as much as 4 dB(A).
