Ultrasound technology uses sound waves produced and detected by a tool called a transducer. An echo is produced when body ...

Any sound above 20 000 Hz is called ultrasound. It is too high pitched for humans to hear, but other animals (such as dogs, cats, dolphins and bats) can hear ultrasound. Ultrasound waves are ...

Most often ultrasonic transducers ... modulated sounds waves. The transmitter and receiver For the transmitter, he turned an Arduino Pro Micro into a USB sound card which he could plug into ...

For the ultrasound test ... and place a device called a transducer on the breast. The transducer releases high-frequency sound waves and picks up the echoes from these sound waves, which a ...

Ultrasound, like audible sounds, is transmitted by means of longitudinal waves. Ultrasound is used in medicine to break up kidney stones and gall stones. It is also used, in a process known as ...

The rig uses a 60W ultrasonic transducer, operating at approximately 40 KHz, to generate a standing wave in combination with a reflector – essentially a rigid piece of material off which sound ...

The University of Virginia's Natasha D. Sheybani, PhD, is exploring the potential of focused ultrasound to improve ...

As the technology advances, it gets cheaper, more portable, and more powerful. Since it uses sound waves, an ultrasound doesn’t put the patient at risk for radiation. Despite its usefulness, ...

At the heart of the technology lies ultrasound—sound waves that travel at frequencies beyond the range of human hearing. While typically silent to our ears, ultrasound waves can be manipulated ...

ultrasonic cleaners use high-frequency sound waves which are produced by an ultrasonic transducer to clean a wide range of items and materials. Most commercially available options operate at a ...
