[QUOTE="Ivan Beaver, post: 14427, member: 30"] Re: Calibrating measurement mics. Assuming your Rat shack is actually right [img]http://www.soundforums.net/images/smilies/icon_rolleyes.gif[/img] I attended a sub get together (home theatre) a couple of years ago and lots of guys brought their SPL meters. All makes and models. My was recently calibrated-so I ''assume'' it was pretty close to a standard. From the highest reading to the lowest reading the range was about 7-8dB [img]http://www.soundforums.net/images/smilies/icon_eek.gif[/img] SO just because it ''says'' so-does not make it so. Consider what a ''real'' SPL meter costs, and then look at the cost of the ''cheapies'' and just think about why the other one cost more. Remember there is a little screwdriver adjust on the side of the meter-so it is very possible to have it drift a bit. A man with a meter is sure. A man with 2 meters is sure of nothing-unless it is traceable. [/QUOTE]
