anyone know how to properly measure the Db level of their pipe? ever had a ranger do it at a park?

my buddy has a Db meter, but we just want to know how far back to stand with it. and does it need to be checked at a particular rpm range? or just revving it?

my scrambler is loud, but not too loud for me[img]i/expressions/face-icon-small-wink.gif[/img]. my buddies complain when they are behind me(cry babies), so i figger i better check it to see if its actually too loud.

lemme know,

it veries depending on the requirments. i no at a local race track its below 108db at 2000 rpm standing 20 feet behind.

 

Most places measure 20" to the rear, and at a 45 degree angle. Est 50% throttle. The Radio Shack digital meter I have has been checked against huge dollar airport units, and sometimes actually displayed readings quicker, and more stable.
