What are the characteristics of ultrasound?[新闻1]
Our ears can distinguish between a frequency of 2-20 the voice of Joseph, frequency than the human range of hearing high-frequency sound is the voice of one of the categories of mechanical waves, sound waves refer to the human ear can feel a vertical wave, the frequency range of 16Hz-20KHz. When the sound waves at frequencies below 16Hz is called infrasound, higher than 20KHz is called ultrasonic sound waves, ultrasound has the following characteristics:
1. Ultrasound in gas, liquid, solid, solid-melt, such as effective communication medium.
2. To convey a strong ultrasonic energy.
3. Ultrasound will produce reflection, interference, superposition and resonance phenomena.
4. Ultrasound in liquid media dissemination, the interface can have a strong impact and cavitation phenomenon.
