Abstract The character and magnitude of compressor noise, the technology and cost of quieting compressors, the validity of manufacturers' data, and propagation of compressor noise in the community are examined in this report. It is found that the noise radiated by portable air compressors is typically nondirective (especially by the quieted compressors). The propagation of air compressor noise in the community is best summarized in terms of construction-site geometry. Quieting air compressors alone will not significantly reduce total noise at construction sites. Comparison of 20 construction-site models shows the maximum reduction of total site noise to be less than 2 dB when the air compressor is quieted by 10 dB. Quieting portable air compressors to 76 or 78 dBA (at 7 m) will not alter the operational performance of the machine, if correct design techniques are used. Based on analytical analyses using present noise control technology, it is concluded that quieting air compressors to 65 dBA at 7 m is feasible.
