Original Abstract

Couplants are necessary in most cases of ultrasonic testing, due to large acoustic mismatch between air and solid material. Signal amplitude as well as wave type are greatly affected by couplant properties. This paper is discussed influence of various coupling methods on received signal in frequency domain. Coupling of both transmitter-specimen and receiver-specimen in a pitch-catch setup are investigated on common building material.
