Using an example of generalized Burgers equations appearing in nonlinear acoustics we show that that the \"direct\" procedure of solving boundary-value problems using Lie symmetries firstly described by Bluman is more general and straightforward than the method suggested by Moran and Gaggioli in [J. Eng. Math. 3 (1969), 151-162].
