Blast Noise Measurements

Navcon Engineering Network has conducted numerous Blast Overpressure and Heat Flux measurement surveys for both commercial and military applications.  The data is often used to assess the suitability of containment shelters and personnel injury when subjected to extreme pressure waves and temperature gradients.  Navcon measurement systems can record blast overpressures greater than 185 dB (10 PSI) at sample rates of 260 kHz.  [ Reference MIL-STD-1474D, MIL-STD-398, MIL-STD-882, MIL-STD-2105C, ... ]

Navcon has also conducted many lower level blast noise surveys recording automotive airbag deployments, construction pile driving, rock crushing operations, mold shop hammers, etc.
