Underwater sensor successfully tested

As part of the Dutch STW SeaSTAR project researchers at the University of Twente have conducted tests using underwater communication and location finding at the Rutbeek water recreation park near Enschede. The aim of the ...

Croaking chorus of Cuban frogs make noisy new neighbors

Human-produced noises from sources such as traffic and trains can substantially impact animals, affecting their ability to communicate, hunt, or even survive. But can the noise made by another animal have the same detrimental ...

Model will unlock mysteries of the voice

Swedish researchers are leading the development of the world's first comprehensive model of the human voice, which could contribute to better voice care, voice prosthetics, talking robots and teaching opportunities.

Crickets' calling song hits the high notes

(Phys.org) —Research has detailed how acoustic communication has evolved within a unique species of cricket which exploits extremely high frequency harmonics to interact.

Making frequency-hopping radios practical

The way in which radio spectrum is currently allocated to different wireless technologies can lead to gross inefficiencies. In some regions, for instance, the frequencies used by cellphones can be desperately congested, while ...

Secret streets of Britain's Atlantis are revealed

A University of Southampton professor has carried out the most detailed analysis ever of the archaeological remains of the lost medieval town of Dunwich, dubbed 'Britain's Atlantis'.

Studying how flocculation affects acoustic reflection

In inland estuaries and shallow coastal waters, small particles of organic matter, such as organic waste and debris or bacteria, clump together to form an aggregate known as floc. Flocculated particles can span a range of ...

Researcher construct invisibility cloak for thermal flow

By means of special metamaterials, light and sound can be passed around objects. KIT researchers now succeeded in demonstrating that the same materials can also be used to specifically influence the propagation of heat. A ...
