This tool is built for mines and quarries that need quick, reliable checks on blast-induced noise and air-overpressure. It converts air-overpressure (Pa) to noise levels (dBL) with the standard acoustic equation:
Keeps every result in line with DMPR and USBM compliance limits. Whether you’re signing off a shot design, compiling an environmental report, or fielding community queries, the calculator delivers the numbers you need—instantly and in plain text.
If you’re working to push noise and over-pressure even lower, explore Varistem® stemming plugs or contact our blasting engineers for tailored advice.
