The ocean is nearly transparent to low frequency sound permitting the observation of distant events such as earthquakes or explosions at fully basin scales. For very low frequency the ocean acts as a shallow-water waveguide and lateral variability in bathymetry can lead to out-of-plane effects. In this paper, data from the International...

The objective of the present laboratory studies was to enable refinements of the current rating procedure for low frequency sounds. To increase our insight into a relevant spectral issue, groups of adjacent frequency bands around 40, 50, and 63 Hz were presented at various sound level combinations. It was concluded that an energy-based summation...

A blast absorber test was conducted at the Aberdeen Test Centre from 13 to 17 June 2005. The test was set up to determine the absorbing and shielding effect of a gravel pile, of 1.5 meters high and 15 by 15 meters wide, on blasts from large weapons: e.g. armor, artillery or demolition. The blast was simulated with single brick C-4 charges of 570...
