Friday 21 Nov 2014The acoustic bubble

Prof. Timothy G. Leighton FREng FRS - University of Southampton

Gas bubbles in liquids are the most powerfully naturally occurring acoustical objects in the world, generating, absorbing and scattering sound. We can use these effects to calculate the contribution that bubbles trapped by breaking sea waves contribute to the transfer of greenhouse gases between the atmosphere and ocean; to determine the safe exposures level for foetal ultrasonic scanning; to predict the soundscapes of other planets; to generate uncommon chemical reactions: and to work out how whales and dolphins use sound in the ocean to catch prey.
