WEINSTEIN: EXPLOSIVE SOUND-SOURCE STANDARDS 



Siommarizing the last three figures, we have propagation-loss 

 uncertainties consisting of both biases and standard deviations as 

 high as about 1.5 dB, which is not a particularly satisfying accuracy, 

 especially since it does not include the uncertainty in source level. 



DATA COMPARABILITY 



Based on the investigations which have been conducted, it is 

 clear that the source levels and processing bandwidths should be 

 documented to permit data comparisons. Some indication of the 

 quality assurance procedures used, or a best estimate of data accu- 

 racy is useful. 



Ultimately, it appears desirable to develop standardized pro- 

 cedures for checking or adjusting processing systems. Some thought 

 is currently being given to this in the LRAPP community using 

 recorded transients to simulate explosive signals but constructed 

 so that the spectral content can be computed by closed analytic 

 forms .
