Ultrasonics

Ultrasonics refers to sound waves with frequencies above the upper limit of human hearing, typically above 20 kilohertz (kHz). In acoustics, this technology is utilized in various applications, such as medical imaging (ultrasound), industrial cleaning, and materials testing. Because ultrasonic waves can penetrate materials and provide detailed information without causing damage, they are invaluable in non-destructive testing, allowing for precise examination of structures. Additionally, ultrasonics can facilitate cleaning procedures, especially for intricate items, by producing tiny bubbles that effectively dislodge contaminants. Overall, ultrasonics harnesses sound beyond conventional hearing for practical and innovative uses.
