ultrasonic sound

Another therapy treats the wound with a device that combines painless ultrasonic sound with a fine saline mist.

Finite difference time domain method was used to research transducer's pulse ultrasonic sound field characteristics and diffuse attenuator.

The resulting ultrasonic sound wave can then be directed out in a tightly controlled beam.

The repetition of the ultrasonic sound and the experiment of zero velocity in gas flowmeter are tested using this speed measurement system.

These high intensity ultrasonic sound waves (20~65KHz) are out of the range of hearing of humans are most household pets, but pests.

So ultrasonic sound's precision identify can be implement through this orderliness.

If there is no ultrasonic sound in the received signal, the maximal value is not in order.

This ultrasonic sound is inaudible to the human ear.

The application of ultrasonic sound system of measuring distance is also presented in this paper .

So if you're standing in front of the ultrasonic sound wave, you can hear the sound.

The test study of the relation between crush intensity and elastic modulus and velocity of ultrasonic sound for concrete
