ultrasonis
Ultrasonics refers to sound waves with frequencies higher than the upper audible limit of human hearing, which is approximately 20 kilohertz (20,000 Hz). These frequencies are beyond what humans can typically perceive. While humans cannot hear ultrasonic sound, many animals, such as dogs, bats, and dolphins, can.
The generation of ultrasonic waves is typically achieved through piezoelectric transducers. These devices utilize the piezoelectric
Ultrasonics has a wide range of applications across various fields. In medicine, ultrasound imaging, or sonography,
In industry, ultrasonic cleaning uses high-frequency sound waves to agitate a cleaning fluid, dislodging contaminants from
