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

Researchers Record Weddell Seals Chirping and Chattering Like Robots Below Ice for the First Time, They Have No Idea Why ...

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 ...

Brainwave testing of two young baleen whales has revealed they can hear higher frequency sounds than previously thought, forcing researchers to rethink how the ocean’s largest animals respond to ...

But a hackier way would be to build a parametric speaker that focuses soundwaves into a narrow beam like [Shane] did with this ultrasonic sound gun. As the directivity of a soundwave depends on ...

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.

Lots of frogs around the world use a scream to scare off predators but scientists have found frogs in the Brazilian Atlantic Forest that can scream at an ultrasonic ... but no sound came out.

Ultrasonic sound is a vibration at a frequency above the range of human hearing, usually greater than 20 kHz. Unlike other types of position sensors, ultrasonic linear position sensors and switches ...

Ultrasonic transducers send and receive waves for many types of sensing. They convert energy into high frequency sound waves in the ultrasonic range. These sound waves are then focused on a target and ...
