Craig N. Dolder, Ph. D. Acoustics

Student Paper Award: First Place in Acoustical Oceanography

This is a post to say that I am honored to have been awarded a best student paper award at the 167th meeting of the Acoustical Society of America for my presentation titled Extracting effective medium properties for fish schools from resonator and free-field measurements.


I was given the award just in the nick of time, seeing that I graduated the weekend after the conference. The presentation detailed my dissertation work on “Direct measurement of effective medium properties of model fish schools.” To make a long and complicated dissertation short, I recorded the resonance frequency of glass tubes filled with water and live zebrafish in order to determine the sound speed of an “effective medium” of fish.

Think of it like an organ pipe, which sounds a certain note. If the substance inside the pipe changes, the resonance frequency changes. Through that frequency change we gain knowledge about the contents. New methods for more precise observation of the acoustic properties of fish schools are in demand, especially in the light of new about large changes in fish populations over just a few generations.

I am currently working on two journal articles detailing the work and its refinement since my dissertation was published.

I’d like to congratulate several of my friends who were also presented with student paper awards:

Adaleena Mookerjee, Univ. of Michigan, for her presentation “Comparison of near-field acoustic coherent backscattering simulations with optics theory and experiments.”

Whitney Coyle, Penn State Univ, for her presentation “Clarinet playing frequency predictions: Comparison between analytic and numeric simulations.”

Anthony Bonomo, Univ. of Texas at Austin, for his presentation “Acoustic scattering from a sand layer and rock substrate with rough interfaces using the finite element method.”
