(Doppler effect is whenever relative motion exists between a source of sound and a listener and the frequency of the sound heard by the listener sounds different compared to the frequency when there is no motion.) The frequency of the

    Ultrasound – Quick Project Ultrasounds are sound waves with frequency beyond the human limits‚ therefore humans are unable to hear them. It even travels at exactly the same speed as sound in any medium. Humans can hear sound within the frequency range of about 20 to 20‚000 Hz‚ so any sound above 20 kHz is ultrasound. Ultrasound or ultrasonography is a medical imaging technique that uses high frequency sound waves and their echoes. The technique is similar to the echolocation used by bats‚ whales

Ultrasound: Above: An ultrasound machine. Ultrasound is the use of energy generated by sound waves of 20‚000 or more vibrations per second. Ultrasounds are generated by a device called a transducer. Bearing in mind that sound is a mechanical energy‚ the transducer

    PHYSICS Why did humans can’t hear the ultrasound unlike the dogs? Ultrasound is a cyclic sound pressure wave with a frequency greater than the upper limit of the human hearing range. Ultrasound is thus not separated from "normal" (audible) sound based on differences in physical properties‚ only the fact that humans cannot hear it. Although this limit varies from person to person‚ it is approximately 20 kilohertz (20‚000 hertz) in healthy‚ young adults. Ultrasound devices operate with frequencies from
