Page 2: 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.

Why do brown bats stop feeding during fireworks?

Firework shows are controversial in this day and age. While beautiful, fireworks are loud, bright, and smoky, and they can be dangerous to the surrounding environment, releasing contaminants into the air and frightening both ...

Can plants hear? Latest research offers new insights

Researchers at MIT have suggested that rice seeds can hear the sound of rain, according to a new study. MIT calls it "the first direct evidence that plant seeds and seedlings can sense sounds in nature." Perhaps surprisingly, ...

New 'Roadmap' highlights surface acoustic wave technologies

With the involvement of scientists from the Paul Drude Institute for Solid State Electronics in Berlin and the Universities of Augsburg and Münster, international researchers have presented a new roadmap for surface acoustic ...

One blue whale song unlocks oceans of data

Trying to find a whale song in the ocean is like trying to find a needle in a haystack. But now, UNSW Sydney researchers say they've trained a model, with just a single case study, to find blue whale songs in recordings that ...
