Ultrasound can do a whole lot more than create images of unborn babies. Since it first became a near-indispensable medical tool in the 1930s, technology that produces sound waves so high-pitched that ...

Ultrasonics or ultrasound is a radar-like system that uses ultrasonic signals at frequencies above those typical for human hearing, usually above 16 to 20 kHz. The 40- to 70-kHz range tends to be most ...

USound’s latest MEMS-based Ready-to-Deploy Ultrasonic Module will be showcased at the upcoming Consumer Electronics Show (CES) in Las Vegas, Nevada. “This ultrasonic module highlights the versatility ...

Ultrasonics refers to signals that are above the human hearing span (>20 kHz), and usually in the 40- to 70-kHz range. These signals are used like radar—they’re radiated toward a target and reflected ...

Ultrasonic sensors measure the distance between a target and the sensor using high-frequency sound waves that are inaudible to humans. The process is simple: the sensor emits ultrasonic waves, which ...

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 ...

RAILWAY AGE MARCH 2022 ISSUE: Welcome to “Timeout for Tech with Gary T. Fry, Ph.D., P.E.” Each month, we examine a technology topic that professionals in the railway industry have asked to learn more ...
