The human ear can hear the sound wave frequency is 20-20 000 Hz, when the sound wave vibration frequency is greater than 20 000 Hz, the human ear can not hear. Ultrasound is named because its lower frequency limit is approximately equal to the upper limit of human hearing. Therefore, we call the frequency higher than 20000 Hz acoustic wave "ultrasonic".
2. ultrasonic is a mechanical wave. Mechanical vibration and wave motion are the physical basis of ultrasonic flaw detection.
main
Ultrasound has many applications in fisheries. It can be used for ranging, measuring speed, measuring obstacles, cleaning, welding, crushing stone, disinfection, inspection of defects in metal products, welding aluminum, washing clothes, drilling in glaze, and looking for sunken ships.
Characteristics of communication
Ultrasound wave length is relatively shorter than sound wave, usually the obstacles will be much longer than the ultrasonic wave, so the diffraction ability of ultrasonic is not very strong, in a certain density of the medium unchanged, ultrasonic wave can travel along the direction of the wave along a straight line consistently, the shorter the wave length of the ultrasonic. The ability to shoot straight is better.
Power characteristics
When sound travels through the air, it pushes particles in the air to vibrate and act on the particles. Acoustic power is the physical quantity that indicates the speed of sound work. At the same intensity, the higher the frequency of the sound wave, the greater the power it has, so compared with the sound wave, the power of the ultrasonic wave is much greater than the sound wave.
Cavitation
When ultrasonic wave propagates through the gap of the liquid, the molecule of the liquid is transmitted by the energy of the ultrasonic wave. The molecule of the liquid has the energy, and the molecule interacts with each other to produce a large number of bubbles. These bubbles constitute the precondition of cavitation. When the energy is gathered to a certain extent, the bubble breaks up and produces a huge amount of energy to the whole. Liquid breakage, cavitation is often used in ultrasonic cleaning machines, as well as small ultrasonic cleaning machine and the principle of application.
