Research news on Acoustics

Acoustics, as a research area, is the scientific study of generation, propagation, interaction, and detection of mechanical waves in gases, liquids, and solids across audible, infrasonic, and ultrasonic frequency ranges. It encompasses theoretical and experimental analysis of wave equations, sound fields, impedance, reflection, refraction, scattering, absorption, and nonlinear effects in complex media and structures. Subfields include physical acoustics, architectural acoustics, aeroacoustics, underwater and ocean acoustics, ultrasonics, vibroacoustics, and acoustical signal processing. Research in acoustics underpins technologies for imaging, nondestructive evaluation, noise control, transducer design, acoustic metamaterials, and advanced measurement techniques for characterizing materials, devices, and environments using sound.

Ghost bat dialects emerge across colonies, study suggests

Accents are usually thought of as a human trait, indicating where a person has grown up or the communities they belong—and new research shows the same dialects can also occur in Australia's largest carnivorous bat.

A new way to eavesdrop on ocean temperature in the Arctic

New research led by scientists at UC San Diego's Scripps Institution of Oceanography finds that the travel time of underwater sounds moving across the Arctic Ocean can be used to precisely measure ocean temperature under ...

Damselfish pick-up lines could have regional accents

Courtship calls among two species of fish commonly found on Australian coral reefs have been described, and researchers say their "accents" can vary significantly between regions. Scientists led by the Australian Institute ...
