I brought a sound level meter home from work. Did a couple of measurements on an 04 88ci dresser with Rienharts and quiet baffles. Best I could figure the bike would pass N.H 106dB and fail Ma. as it looked to be over 96dB. Anyone out there have any kind of standards on how to actually set the test up? Distance, angles,height,rpms all have an effect on the reading even the scale settings on the meter (weghted or not , peak or average) Also wondering if there is a federal standard and if the states are different which standard would prevail. Since I been riding I hate to think about all the pipes I have gone thru. I know it would fill a small garage. Straights,baloney,slash,tapperd,shotgun,fishtail with and without baffles,bubs,Dunstall Silencers,Reinhart ,Se to name few.Never new about dyno's till a couple of years ago. Well I'm just a hobbyist and curious about taking sound level readings and looking for some standards on how to take readings. Thanks
