What wave is ultrasound?
Ultrasound is a sound wave with a frequency higher than the human hearing range, usually referring to sound waves with a frequency exceeding 20,000 Hertz (Hz). It is widely used in medicine, industry, military and other fields. This article will introduce in detail the definition, characteristics, applications and hot topics of the past 10 days.
1. Definition and characteristics of ultrasonic waves
Ultrasound is a type of mechanical wave whose frequency is higher than the range of sound waves that the human ear can hear (20Hz-20kHz). It has the following features:
| Features | Description |
|---|---|
| frequency range | Typically 20kHz to several GHz |
| propagation speed | About 343m/s in air, about 1500m/s in water |
| Directionality | High-frequency ultrasonic waves have strong directionality |
| Penetrating ability | Able to penetrate most non-metallic materials |
2. Application fields of ultrasound
Ultrasonic technology is widely used in modern society. The following are the main application areas:
| Application areas | Specific applications |
|---|---|
| medical diagnosis | B-ultrasound examination, echocardiography, Doppler ultrasound, etc. |
| Industrial testing | Material non-destructive testing, thickness measurement, defect detection |
| clean technology | Ultrasonic cleaning of precision instruments and parts |
| military applications | Sonar systems, underwater detection |
| beauty field | Ultrasonic beauty instrument, skin care |
