Patterned elastic plate guides ultrasonic waves and traps different frequencies at separate bulk locations, enabling compact ...

Endoscopic ultrasound (EUS) plays a vital role in the development of novel treatment and diagnostic methods of gastrointestinal diseases. The ultrasonic transducer is an essential component, whose ...

Humans can observe what and where something happens around them with their hearing, as long as sound frequencies lie between 20 Hz and 20 000 Hz. Researchers have now developed a new audio technique ...

Research conducted by a team of scientists from Kaunas University, Lithuania, revealed that low-frequency ultrasound influences blood parameters. The findings suggest that ultrasound's effect on ...

Researchers created a high-resolution 3D ultrasonic imaging system for concrete that uses broadband ultrasonic signals to automatically adapt to different types of concrete structures. WASHINGTON, Jan ...

A new study has shown how Japanese horseshoe bats (Rhinolophus nippon) handle noisy environments ...

THERE is much circumstantial evidence that, in the majority of birds at least, the communicative function of call notes and song depends principally if not entirely on those frequencies which fall ...
