NAG Meeting 03-06-13

At our March 6 NAG meeting, Josh Thede presented on the measurement of acoustic absorption.  His undergraduate research project, funded by a UNL UCARE grant, focused on measuring the absorption properties of a number of foam products using an impedance tube.  The greatest difficulty is cutting a perfect circle of the product to use with the tube!  The acoustic nugget of the week was on the US National Park Service Natural Sounds webpage… lots of fun stuff to be found there!
