Absorption of ultrasonic waves in air

  title={Absorption of ultrasonic waves in air},
  author={A. Vladi{\vs}auskas and L. Jakevicius},
Increasing interest in the use of air-coupled ultrasonic measurements, inspection and monitoring is based on the fact that non-contact methods are getting advantage and are promising in new future technologies. At present ultrasonic investigation in the air environment covered many fields of the production and industry. Ultrasonic waves are successfully used to measure distance [1], thickness [2], to generate and receive Lamb waves in the plates [3], in non destructive evaluation [4], to… CONTINUE READING
