Blast Noise Standards and Instrumentation.
NTIS: PB 233 425 :18 pages
A Bureau of Mines survey of noise from quarry production blasting was conducted at seven crushed-stone quarries, providing information on close-in noise generation, comparative instrumentation, and evaluation of the sound levels as related to blasting parameters and existing state and local noise standards. The results from this preliminary survey will be useful in the design of a complete investigation of the problem of noise from blasting. There exists an immediate need for technical guidelines for noise pollution control agencies presently working on the regulation of impulsive noise sources. This survey and results from previous work by other researchers are used to derive interim recommendations on weighting scales, generated sound levels, and instrumentation. These recommendations are based on the limited data presently available and may be modified with subsequent investigation of noise generation, propagation, structural damage, and human tolerance.
