Acoustic device makes piezoelectrics sing to a different tune

In today's "internet of things," devices connect primarily over short ranges at high speeds, an environment in which surface acoustic wave (SAW) devices have shown promise for years, resulting in the shrinking size of your ...

Underwater acoustic localization of marine mammals and vehicles

Researchers at IMDEA Networks (Spain) in collaboration with University of Haifa (Israel) have developed an underwater acoustic system for the localization of marine mammals, underwater vehicles and other sound sources in ...

Acoustics of ancient Greek theaters found to be good, not great

Tales of the acoustics at the 2300 year-old Greek theater of Epidaurus tend to be told in terms of superlatives. Not actually justified, according to measurements taken by researchers from Eindhoven University of Technology. ...

Spider-web 'labyrinths' may help reduce noise pollution

(Phys.org)—Researchers have demonstrated that the geometry of a natural spider web can be used to design new structures that address one of the biggest challenges in sound control: reducing low-frequency noise, which is ...
