[QUOTE="SpeedyManiac, post: 1174136, member: 19453"] I know the tests predates the modern four stroke, but what I'm saying is from what I can tell, the four strokes have an advantage of testing lower than their true sound level and that the test should be changed. I know that lower frequency sounds carry farther, but I'm addressing a very specific issue that in terms of absolute sound pressure levels, using the dBA scale gives four-strokes a slight advantage, and if they went to using the dBC scale, it would level the playing field, so to speak. I know there are many variables in sound testing, but all I'm saying is that the scale they are currently using is the wrong one for sound testing motorcycles and using a frequency neutral scale would help put all bikes on a level playing field.
