gr4techie raises a very important point here. The graphic showing how all the fast jets are "fairly consistant" in their noise levels is very misleading, using a log scale that few people understand to falsly make a point. For example, the 148 bd of an F-35 in burner is actually twice the volume of the 145 db in cold power - even though it looks virtually the same on the graph. Poor choice of illustration vithout a proper explanation.
