Dwight Wayne Batteau, D.Sc. (September 25, 1916 - October 26, 1967) was an acoustic engineer. His research established that the shape of humans' outer ears (Auricle) provides directional hearing. He also developed a "Man to Dolphin Translator" which allowed 2-way communication by converting in both directions between vowel sounds and whistles. He was a professor at Harvard University, then at Tufts University and was an officer of acoustic research companies, United Research Inc. and Listening Post, Inc.
