    J Acoust Soc Am 130:3421-30. 2011
    ..This approach allows for robust attenuation measurements over a much wider frequency range and enables accurate measurements from lower-quality spectral peaks...

    J Acoust Soc Am 129:74-84. 2011
    ..In addition, although the driving mechanism of neck collapse is always consistent with the data for the larger bubble of the newly formed pair, a different mechanism must be driving the smaller bubble in some situations...

    Institute of Sound and Vibration Research, University of Southampton, Highfield, Southampton, Hampshire SO17 1BJ, UK
    J Acoust Soc Am 129:EL83-8. 2011
    ..The model predicts the right order of magnitude for the acoustic amplitude, and the predicted amplitudes also scale correctly with the radius of the smaller parent bubble...

    Marine Physical Laboratory, Scripps Institution of Oceanography, La Jolla, California 92093 0238, USA
    J Acoust Soc Am 128:2625-34. 2010
    ..It is found that for slowly-grown bubbles the jet does make a noticeable difference to the total volume decrease during neck collapse, but that it is not a dominant effect in the overall acoustic excitation...

    Grant B Deane
    Scripps Institution of Oceanography, University of California San Diego, La Jolla, California 92093 0238, USA
    J Acoust Soc Am 123:EL126-32. 2008
    ..Experiments and models presented here show that sound from bubbles released from a nozzle can be excited by the rapid decrease in volume accompanying the collapse of the neck of gas which joins the bubble to its parent...
