*** iPod Touch users! ***

Please note that the iPod Touch doesn't have a built in mic! You will need an iPhone Headset or similar to be able to use Decibel. Most of the bad reviews are due to this fact. So please don't judge Decibel based on that. Thank you!


Have you ever wondered how loud a sound is? Screaming kids, a rock concert, sport fans screaming? Wonder no more. Measure it with Decibel!
