Blast wave propagation measurements were conducted to investigate nonlinear propagation effects on blast waveform evolution with distance. Measurements were made with a wide-bandwidth capacitor microphone for comparison with conventional 3.175-mm (1/8-in.) microphones with and without baffles. It was found that the 3.175-mm microphone did not have sufficient high-frequency response to capture the actual rise times in some regions. For a source of 0.57 kg (1.25 lb) of C-4 plastic explosive, the trend observed is that nonlinear effects steepened the waveform, thereby decreasing the shock rise time, up to a range of 50 m. At 100 m, the rise times had increased slightly.
进行了冲击波传播测量，以研究冲击波波形随距离的非线性传播效应。使用宽带电容式传声器进行测量，并与带有和不带有障板的传统3.175毫米（1/8英寸）传声器进行比较。结果发现，3.175毫米传声器没有足够的高频响应来捕捉某些区域的实际上升时间。对于0.57千克（1.25磅）C-4塑料炸药源，观察到的趋势是，非线性效应使波形变陡，从而缩短了冲击上升时间，最大可达50米的距离。在100米处，上升时间略有增加。
