Comb Filtering and Acoustical Interference are two audio terms that relate to the manner in which two or more sound sources (such as two speakers or two drivers within a speaker system) interact and ...

Researchers have developed a method to control sound waves, using a computational approach to inversely design acoustic filters that fit within an arbitrary 3-D shape while achieving target sound ...

New York -- July 18, 2016 -- Columbia Engineering researchers, working with colleagues at Disney Research and MIT, have developed a new method to control sound waves, using a computational approach to ...
