If you want to play with radar — and who could blame you — you can pretty easily get your hands on something like the ...

Research reveals that moths use ultrasonic sounds from drought-stressed plants to guide their egg-laying, favouring healthier ...

This study reveals that female moths utilize ultrasonic sounds emitted by dehydrated plants to inform their oviposition decisions, highlighting sound as a potential sensory cue for optimal host plant ...

Understanding that whales can hear a broader range of frequencies, including ultrasonic sounds, suggests that they may be more vulnerable to anthropogenic noise than previously assumed. This ...

Scientists have been scratching their heads about the purpose of the ultrasonic vocalizations (USVs) made by rodents since these sounds were first discovered in the 1950s. A widely accepted theory ...

A team of marine biologists from Norway, the U.S. and Denmark has conducted the first hearing test of a live baleen whale.

Ingeniously integrating ultrasonic noise into the original vocal recordings, our method can mislead sophisticated deep learning systems while remaining undetectable to the human ear, leading to ...

They’re tuned to that specific sound, and they know the meaning, and they consider it.” In an earlier study, researchers showed that some plants emit ultrasonic clicks when under stress.

USound, the global leader in MEMS loudspeakers, today announced the showcase of its fully developed ultrasonic sensing module ...

And as we age, our hearing gets worse, eliminating even more sounds from the range of audible noises. For comparison, bats can hear ultrasonic sounds with frequencies of up to 110,000 hertz.

A pelvic ultrasound scan uses high frequency sound waves to create a picture of the area between your hip bones (your pelvis). It it sometimes called a gynaecological ultrasound. The ultrasound ...

In the TBS, the distribution of sound pressure in the sound field is used as a constraint condition to provide a reference for the design of ultrasonic transducers. Considering a focused ultrasound ...
