Method of determining average sound attenuation by approximation

摘要

The invention relates to a method of determining by approximation the average sound attenuation (damping) in an object (1) under investigation. According to to the invention, the sound amplitudes (s1 and s2) of the echo signals (5 and 8) emanating from at least two transducer positions lying opposite each other and reflected at a diffuser (2) located in the object (1) under investigation are measured. As a result, the local damping properties of a medium under investigation can be displayed. <IMAGE>
