Acoustics News
Acoustics is the branch of physics that deals with the study of sound, its production, transmission, and effects. This field encompasses a broad spectrum of topics, including the generation and detection of sound waves, their propagation through different mediums, and their interaction with materials and structures. Acousticians explore how sound waves behave in various environments—from tiny rooms to large concert halls—and how these waves influence human perception and activity.
