Sound power is considered as an excellent measure for evaluating the efficiency of noise controls as well as for comparing noise sources in workrooms. This parameter can be determined by sound pressure or intensity based methods in real conditions of workrooms. This paper aims empirically to compare these in situ methods in relation to a typical industrial machine located in workroom ... https://www.ngetikin.com/flash-choice-1-Gallon-Roll-Cote-High-Performance-Moisture-Vapor-Barrier-Coating-and-Primer-limited-super/
