What process of disinfection employs sound waves?

Ultrasonic disinfection is the correct process that employs sound waves for cleaning and disinfection purposes. This method utilizes high-frequency sound waves that generate microscopic bubbles in a liquid solution, often referred to as cavitation. As these bubbles implode, they create strong shock waves that can dislodge dirt, debris, and microorganisms from surfaces, including instruments and tools used in medical and aesthetic practices.

This process is particularly effective for cleaning intricate items and tools that have complex shapes or hard-to-reach areas, ensuring thorough disinfection. The gentle yet powerful action of ultrasonic waves allows for a more efficient and effective cleaning compared to methods that rely solely on mechanical scrubbing or chemical disinfectants. This makes ultrasonic disinfection a valuable technique in ensuring that instruments are adequately sanitized and safe for use.
