Overview
Ultrasound technology is concerned with sound waves
that occur above human perception. The average
threshold of human perception is 16,500 Hz.
Although the highest sounds some humans are
capable of hearing is 21,000 Hz, ultrasound
technology is usually concerned with frequencies from
20,000 Hz and up. Another way of stating 20,000 Hz
is 20 kHz, or kilohertz. One kHz is 1,000 Hz.
