There are a million stories in that big place they call The University. Some of them are about people making a living from the peculiar way the density of water changes when it is compressed. This is one of those stories.
It’s about a handful of men who measured the directivity pattern of a low frequency transducer using the sound scattered from a high amplitude, high frequency sound beam, called the pump. Not only that but they placed the pump so close to the transducer that most of the sound-sound interaction region was in the nearfield of the transducer! It is also the story of one man who tried to explain their results.
This talk is rated PG-13 (a few brief scenes of mathematical gore). Non-acousticians are urged to attend as the speaker is not an acoustician and will otherwise feel intimidated.
