Ultrasound devices operate with frequencies from 20 kHz up to several gigahertz. A vibration capable of causing such sensations. Ultrasound has much shorter wavelengths than audible sound, so that it propagates in a much narrower beam than any normal loudspeaker system using audio frequencies. Ultrasound is sound waves with frequencies higher than the upper audible limit of human hearing.Ultrasound is not different from "normal" (audible) sound in its physical properties, except that humans cannot hear it. Tweet; If your doctor orders a pelvic ultrasound exam, images can be captured in two different ways: transabdominally (through the abdomen) and transvaginally (through the vaginal canal).
