Decibel readers and iPhone apps

If you're having noise problems in your home or business, you can measure the decibel level with inexpensive apps on your iPhone or buy a decibel-reading device. I downloaded a free app from the App Store called "Decibels" and purchased an inexpensive one - with more features -- called "SPL Meter," but there's many to choose from (just search for "spl meter"). Basically these apps help you measure the decibel volume in your home when it's quiet, and again in different noise situations -- your neighbor's TV or stereo, the sound of cars and trucks outside your windows, the sound of barking dogs, crying babies, etc. [update, Dec 2013: see this review of 30 decibel-reader apps.] All rooms have a decibel level, even when you think you're sitting in silence.

(They recommend, of course, adding a second layer of drywall with Green Glue afterwards). You'll forfeit an additional 1.5 inches of room depth on each side if you use this method. It would be helpful if they supplied before and after specs for room acoustics!
