An ultrasound massager offers a high-tech, low-impact way to treat aching muscles and loosen spasms. Standard massagers often violently shake tense muscles soft. Their noise and pounding can irritate you. Ultrasonic massagers use high frequency sound to stimulate your tissue, eliminating the noise and impacts of outdated massagers.

What is Ultrasound?

Sound vibrations travel in waves. How frequently waves follow each other is called frequency. You sense frequency in a sound’s pitch, not its volume. Science measures it in waves per second called Hertz (Hz). Most people cannot hear frequencies below 20 Hz. For comparison, a piano’s lowest note vibrates 27 times per second, or 27 Hz. Its highest note vibrates beyond 4,000 times per second, just one-fifth the highest tone you can hear. Ultrasound frequencies exceed 20,000 Hz, or 20 kilohertz (kHz). Ultrasound simply means sound vibrating faster than you hear.

Uses of Ultrasound

Though we do not hear them, ultrasonic waves still shake things, the way a booming bass speaker shakes a window. A 30 kHz frequency, for example, vibrates enough to clean tarnish from jewelry, without damaging the jewelry itself. You have probably seen an ultrasound photo of a fetus. That takes wavelengths from 2 million to 18 million Hertz, or 2 to 18 megahertz (MHz), almost 1,000 times the highest audible frequencies.

How Ultrasonic Massagers Work

Usually starting at 1 MHz, ultrasound massagers send sound waves deep into your tissue, vibrating on cellular levels. These pulses loosen your muscles, help your blood flow, and heal injuries quicker. How deep the vibrations reach has less to do with frequency than intensity. You sense intensity as volume. Just like the louder, you shout the more easily you are heard through a wall, louder ultrasound more easily penetrates solid objects. The difference is, you will never hear this because the frequency is already too high.
