In addition to the influencing variables already mentioned, these other factors affect the curve shape:
• sound attenuation
• transfer losses
• amplitude correction value
• probe
Also, the following probe parameters affect the curve shape:
• element or crystal diameter
• frequency
• delay length
• delay velocity
You can adjust these parameters in such a way that you can use the DGS method with many different probes and on various materials.
