This paper presents a comparison of the sonic boom propagation results obtained by ONERA and Dassault Aviation for the two test cases of the third AIAA Sonic Boom Prediction Workshop with their two propagation codes, respectively BANGV and DABANG. In addition to the material presented during the workshop, a more in-depth analysis of some ray-tracing results such as the data along the acoustic rays is presented. Such code-to-code comparisons proved to be useful to detect and correct minor coding differences and mistakes that can be present in codes and therefore increase the confidence and validation of these codes.
