ASA S1.18-2010 Template for Measuring Ground Impedance

standard by American National Standards of the Acoustical Society of America, 03/25/2004

Full Description

This American National Standard describes procedures for obtaining the real and imaginary parts of the specific acoustic impedance of natural ground surfaces outdoors. The Standard uses templates to compare measured sound pressure level differences with a specific set of calculated level differences. The impedance values are obtained from a model based on best fit of measured and calculated level differences. The Standard may be used to obtain the impedance of porous sound absorbing material.
