| Abstract: | 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 im-portance are: (1) the desired resolutions for the measured parameters (peak pressure, rise time, time to zero-crossing, peak under-pres-sure); (2) the sensors and data-acquisition equipment used; (3) post-measurement corrections and digital correction filters; and, (4) laboratory evaluation compared to field measurements. |
