| Abstract |
This report presents the results of a study to assess the costs and attendant benefits/penalties to quiet portable air compressors. The report indicates that a mean list price of $43.32 per cfm is required to quiet gasoline-engine powered compressor models to 76 dBA at 7 m (per the ISO 2151-1972 test procedure). Corresponding figures for diesel-engine driven units are 76 dBA at $52.11 per cfm for those delivering 500 cfm or less and 78 dBA at $48.70 per cfm for those delivering more than 500 cfm. Lower noise levels and higher prices are similarly determined for the 'quietest' decile. Noise reduction to achieve the sound pressure levels of the present average quieted machine, the quietest decile, and levels below the quietest is accomplished for each regimen by the use of three overlapping technologies: sound insulation, sophisticated sound insulation and vibration isolation, and noise source elimination such as fan redesign and alternative engine designs. |
