The Decibel iPhone 3G application from Gadget Frontier transforms your iPhone into a portable decibel meter. Decibel features an analog meter and digital display with peak, average and max in one clean interface. Having used Decibel it appears to be very accurate (probably due do the excellent microphone in the iPhone 3G). The Gadget Frontier website states:

“Even though we have tested Decibel with professional grade equipment with very good results, this application is for recreational use only. iPhone 3G is recommended since it has a better performing microphone than the first generation iPhone.”

Decibel was featured in the BBC show Panorama – The World’s longest running investigative TV show on April 20! The host Quentin Letts use Decibel on his iPhone to measure decibel levels in regards to UK’s health and safety regulations. Check it out on BBC (10 minutes into the show)!

Available now from the iTunes App Store for ¢.99, it is an excellent backup for any audio professional in the field and certainly more than adequate for the rest of us.  View the video review by thedigitallifestyle.tv below.

Note that the iPod Touch doesn’t have a built in microphone. To use Decibel with the iPod Touch will require an iPhone headset or plug-in microphone.

The Decibel App for the iPhone and iPhone 3G (Recommended) is available in Paid Version for (¢.99) from the App Store.
