Improvement of Air Blast Measurement
Abstract
A study was conducted to improve the accuracy of air blast measurements in the range of 170 to 190 dB (6 to 60 kPa or 1 to 10 psi). The primary application of these measurements is to determine human tolerance to muzzle blast produced by Army weapons. A variety of electrical, mechanical, and environmental sources of measurement problems are documented. Extensive testing of a variety of transducers and calibration techniques were conducted in the laboratory. Outdoor field tests were also conducted, several examples of field test data are provided. It was concluded that when the best possible measurement techniques are used, single channel, laboratory measurements using hand picked transducers could be made to an accuracy of + or - 2%. Accuracy for meticulously conducted, multi-channel field tests can be as good as + or - 5 to + or - 10%.
