What process of disinfection uses sound?

The process of disinfection that uses sound is ultrasonic disinfection. This method employs high-frequency sound waves, typically beyond the range of human hearing, to create cavitation bubbles in a liquid. When these bubbles collapse, they produce intense pressure and temperature changes, effectively removing contaminants from surfaces and facilitating the disinfection process.

Ultrasonic disinfection is especially effective in cleaning delicate instruments and items that have intricate designs, as the sound waves can access small crevices and ensure thorough cleaning. Unlike other disinfection methods, ultrasonic cleaning does not rely on heat or chemicals but rather on the physical action of the sound waves, making it a unique and efficient option within various industries, such as healthcare and beauty.
