The sheer abundance of noise that surrounds us makes it necessary for the brain to filter out selective components so that we can focus on what we need or want to hear. This is called filtering. When ...

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 ...

Need to reduce high-pitched noises? Science may have an answer. In a new study, theoretical physicists report that materials made from tapered chains of spherical beads could help dampen sounds that ...

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 ...
