Recording System for Blast Noise Measurement.
Sound and Vibration 1977 Jun; 11(6):20-23
A multichannel recording system was built by the Bureau of Mines to investigate the impulsive noise and vibration produced by blasting in surface mines and quarries. Current application of the system includes the monitoring of both noise overpressures and vibrations inside and outside residential structures to assess damage and annoyance potential, structural response, and the comparative effects of ground and airborne blast vibrations.
