Ultrasonic emitters are devices that produce sound waves at frequencies higher than the upper limit of human hearing, typically above 20 kHz. These sound waves can be used for various applications, including cleaning, pest control, and medical imaging. The technology relies on the principle of sound wave propagation, which allows it to interact with different materials and environments. In industrial settings, ultrasonic emitters are often used in ultrasonic cleaning systems to remove dirt and contaminants from surfaces. In healthcare, they play a crucial role in ultrasound imaging, helping doctors visualize internal organs and monitor fetal development. Their versatility makes them valuable in many fields.
