Blast Absorber Feasibility Test - Short Range Measurements Aberdeen Test Center, MD

摘要

Complaints about Army training noise, especially artillery noise, are increasing and are impacting soldier training opportunities. One suggested mitigation method is to use a gravel pad near the noise source to reduce blast noise. Measurements were conducted to assess this method by detonating C4 charges located over a 15- x 15- x 1.5-m-thick gravel pad or over undisturbed ground and recording the acoustic and seismic waveforms at various distances from the source. The measurements recorded by ERDC-CRREL personnel at propagation distances from 10 to 400 m are documented in this report. Additional reports documenting the longer distance measurements and analyzing the measurements are planned.
