We concluded that the fish had learned to associate the noise generated by divers with feeding opportunities (Chapman et al., 1974; Chapman, 1975).

The supersonic aircraft Concorde, flown by British Airways and Air France, flew at twice the speed of sound, and because of the sonic booms, it generated many countries would not allow flights over their land. Again, use was made of the near field effect to expose the salmon to different ratios of sound pressure and particle motion. This small project was undertaken with the aim of discovering more about the herring fishing in the Loch Torridon area.
