ultrasound is an imaging modality that uses high frequency sound waves to produce images. ultrasound is sound with a frequency above 20,000 hertz (hz) and is undetectable by the human ear. the following frequencies are a guide to frequencies typically used for ultrasound examination:

Frequency And Ultrasound Less than 15 hz is infrasound, 15 hz to 20,000 hz (20 khz) is audible sound, and above 20 khz. ultrasound frequencies range from 2 to approximately 15 mhz, although even higher frequencies may be used in some situations. by definition, “ultrasound” refers to sound waves at a frequency above the normal human audible range (>20 khz). ultrasound is an imaging modality that uses high frequency sound waves to produce images.
