Estimation of the Length of the Near Zone of a Rectangular Transducer
Source abstract
Abstract
The length of the near zone of a rectangular transducer is calculated directly. The results obtained are compared with formulas for calculating the length of the near zone recommended by the European Standard EN 12668-2.
The source flagged this abstract for review. Check formulas and completeness against the original publication.
