Does the airflow have impact on the Muffler?

Does the airflow have impact on the Muffler?
When the airflow passes through the muffler, a new noise is superposed to the original pipe noise and thereby the real use effect of the muffler is affected. This noise is airflow-regenerated noise that is radiated as a result of local resistance force applied to airflow, turbulent flow generated by frictional resistance or vibration of muffler components activated by airflow. The value of the airflow-regenerated noise depends mainly on airflow speed and the structure of the muffler. In general, the higher the airflow speed or the more complicated (such as duct section mutation, bend or obstruction, etc.) the internal structure of the muffler, the bigger the noise generated.
