ultrasonor

Ultrasonor is an adjective used to describe phenomena, devices, or techniques that involve ultrasonic waves or ultrasound—sound waves with frequencies above the upper limit of human hearing, roughly 20 kHz. In many languages, ultrasonor or ultrasonore is used as a direct cognate of the English term ultrasonic, while English typically uses ultrasound for the noun and ultrasonic for the adjective.

Ultrasonic waves have short wavelengths and can propagate through gases, liquids, and solids with frequency-dependent speeds and attenuation. Frequencies used in practice range from about 20 kHz to several megahertz. Lower-frequency ultrasounds are common in industrial cleaning and welding, where deeper penetration is useful; higher-frequency ultrasound (around 1–15 MHz) is standard for diagnostic medical imaging, providing higher spatial resolution.

Applications of ultrasonor technologies span medicine, industry, and research. Medical ultrasound uses transducers to emit and receive echoes, enabling real-time imaging of internal tissues and vessels. In nondestructive testing, ultrasonics reveal internal flaws in metals and composites. Ultrasonic cleaning employs cavitation in liquids to remove contaminants from complex surfaces. Ultrasonic welding joins plastic and some metal components by localized heating at the interface. Additional uses include flow metering, homogenization, sonochemistry, and acoustic sensing.

Technology and components: Ultrasonic systems rely on transducers that convert electrical energy into mechanical vibrations and back, often based on piezoelectric crystals or magnetostrictive materials. Coupling media, matching layers, and transducer design determine penetration, resolution, and efficiency.

Safety and standards: Appropriate exposure levels are essential; high-intensity ultrasound can cause heating and cavitation. Standards and guidelines from health, industrial, and safety organizations regulate usage, especially in medical diagnostics and manufacturing.
