Noise reduction characteristics of prefabricated sound-isolating enclosures: a laboratory, field measurement, and theoretical analysis.
The noise reduction characteristics of prefabricated sound-isolating enclosures were evaluated. Two enclosures from each of two manufacturers were evaluated for noise reduction characteristics following ASTM 596-78 methods. Thirteen enclosures were field-evaluated for noise reduction using two different procedures. The differences between laboratory- and field-determined noise reduction measures are considered and a theoretical model of noise reduction by audiometric enclosures is evaluated.
