This work evaluated the accuracy of blast-wave measurements using commercial measurement-grade condenser microphones. The principal advantages of measurement microphones are their ease of calibration and wide acceptance as measurement standards in acoustics. A number of special techniques are discussed for improving the results obtained with these microphones. Of particular importance are 1 the desired resolutions for the measured parameters peak pressure, rise time, time to zero-crossing, peak under-pressure 2 the sensors and data-acquisition equipment used 3 post-measurement corrections and digital correction filters and, 4 laboratory evaluation compared to field measurements.
