Title: Stonehenge, Cocktail Parties, and Reverberation Chambers
Abstract: Acoustics and electromagnetics have many parallels based on similar equations describing propagation, reflection, and reverberation. Acoustic reverberation chambers predate electromagnetic reverberation chambers and early electromagnetics research took advantage of acoustics results. This talk will look at some similarities between acoustic and electromagnetic reverberation chambers and ask the question, are there still lessons to be learned from acoustics? We will then consider one example, the “cocktail party effect”, that describes speech comprehension in the presence of multiple background conversations. An electromagnetic equivalent is developed that may have application to describing the quality of a wireless communications link in the presence of multiple and similar background signals.
