Abstract:
The invention relates to a device ( 01 ) for examining a test material ( 02 ) via acoustic spectroscopy, comprising a measuring distance ( 37 ) which is formed from a reference material ( 38 ) and the test material ( 02 ), the acoustic material parameters of the reference material ( 38 ) being known for different frequencies, and the length (x R ) of the reference material ( 38 ) being known, and the length (x M ) of the test material ( 02 ) being known, and comprising an ultrasonic transmission device ( 39 ) for transmitting an ultrasonic transmission signal ( 42 ) having an initial amplitude (A 0 ) through the measuring distance ( 37 ), and comprising a first ultrasonic reception device ( 41 ) for receiving the transmitted ultrasonic reception signal ( 44 ) after said signal ( 44 ) has passed through the measuring distance ( 37 ), and comprising a second ultrasonic reception device ( 40 ) for receiving the ultrasonic receiving signal ( 45 ) reflected on the boundary surface ( 43 ) between the test material ( 02 ) and the reference material ( 38 ) after said signal ( 45 ) has twice passed through the reference material ( 38 ) or test material, said transmission device ( 39 ) being configured for giving ultrasonic transmission signals ( 42 ) having different frequencies (f) and the two reception devices ( 40, 41 ) being configured for receiving corresponding ultrasonic reception signals ( 44, 45 ) having different frequencies.
