Abstract
The Bureau of Mines has investigated techniques and instrumentation that measure accurately the airblast overpressures from surface mine blasting. The results include equivalencies between broadband research instrumentation and commercially available impulse precision sound level meters measuring: root-mean-square, peak, fast, slow, impulse, a and c weighting, c-weighted sound exposure level (csel), and "linear" (flat) response. These values were obtained from field measurements and broadband fm tape recordings of production blasts at area and contour coal mines, limestone quarries, and iron mines. Frequency response was determined for 14 commercial systems.
