Abstract
A device for examining a test material via acoustic spectroscopy, including a measuring distance which is formed from a reference material and the test material an ultrasonic transmission device for transmitting an ultrasonic transmission signal having an initial amplitude (A0) through the measuring distance, a first ultrasonic reception device for receiving the transmitted ultrasonic reception signal after the signal has passed through the measuring distance, and a second ultrasonic reception device for receiving the ultrasonic receiving signal reflected on the boundary surface between the test material and the reference material after the signal has twice passed through the reference material or test material, the transmission device being configured for giving ultrasonic transmission signals having different frequencies (f) and the two reception devices being configured for receiving corresponding ultrasonic reception signals having different frequencies.
