Just wanted to post, if you have an iphone there is an SPL meter app for the phone, you can use the mic on the phone or hook up an external mic with this app. i use it all time and is very accurate even from the phones mic. There are a couple out there so make sure you look for (Soundmeter) i got this app for $10 and was well worth the money and have tested it against the radio shack model and is just as accurate with the phones mic and even more accurate when using and external mic.

Hope this helps some people
