DeepSqueak tool identifies marine mammal calls

Lurking beneath the ocean's surface, marine mammals use sound for navigation, prey detection, and a wide range of natural behaviors. Passive acoustic data from underwater environments can provide valuable information on these ...

Smallest earthquakes ever detected in micron-scale metals

On the micrometer scale deformation properties of metals change profoundly: The smooth and continuous behavior of bulk materials often becomes jerky due to random strain bursts of various sizes. The reason for this phenomenon ...

Global study on bird song frequency

An analysis of the songs of most of the world's passerine birds reveals that the frequency at which birds sing mostly depends on body size, but is also influenced by sexual selection. The new study from researchers of the ...

Pump down the volume: Study finds noise-cancelling formula

Noisy, open-plan offices full of workers hunched over desks while wearing noise canceling headphones could soon be a thing of the past, thanks to new research from The Australian National University (ANU).

Numerical model pinpoints source of precursor to seismic signals

Numerical simulations have pinpointed the source of acoustic signals emitted by stressed faults in laboratory earthquake machines. The work further unpacks the physics driving geologic faults, knowledge that could one day ...

Can sound protect eagles from wind turbine collisions?

Every year, bald and golden eagles are killed when they inadvertently fly into wind turbine blades. One possible way to prevent these deaths is to chase the birds away with acoustic signals—sound. To determine what types ...
