In the paper a non-contacting ultrasonic examination of materials is presented. This method is based on the use of air or another gas as a transmission medium for ultrasonic waves between probes and the examined material. This paper concentrates on examination of three materials: polyurethane foam, balsa wood along and across fibres and porous ceramics. It was shown that quality assessment of different material is possible on the basis of spectral analysis of ultrasonic signal transmitted through a sample.
