Pair of Reflection Blocks with Delay Line
The Pair of Reflection Blocks with Delay Line are polished polyacrylate blocks used to investigate multiple echoes and measure frequency-dependent attenuation. A 4MHz transducer is especially suitable for such measurements. An echo pattern comprising at least 3 echoes is recorded, and the spectra of the individual echoes analyzed. The result of the analysis is a shift in the average frequency toward lower frequencies, due to a stronger attenuation of the signal's high-frequency components.
