NoiseLevel

NoiseLevel is a fun way to measure the sounds in your surroundings. Measure the sound level of the music you listen to, your kids playing or your office environment.

NoiseLevel uses your iPhone's built-in microphone, or the iPhone headset microphone, to first pick up sound and then displays it in dB (= decibels) on a status bar at the bottom of NoiseLevel's main screen.

Sounds are also displayed visually as a balloon whose size and color change according to the level of the sound measured. See the balloon burst at high sound levels - you can also make it burst by creating a sharp, high sound, for an example by clapping your hands. Have fun experimenting!

For best results, turn the iPhone so the microphone is pointing directly at the sound source. The screen flips accordingly.

NoiseLevel also works on iPod Touch, 2nd generation, but only if you use an iPhone headset with microphone.

Disclaimer:
NoiseLevel is fairly accurate but it should NOT be considered a professional sound level meter. The built-in microphone of the iPhone can only measure values between 40 to105 dB and values may vary slightly between iPhones.

Customers say:

"I use this app in my classroom and it works perfectly for me. It gives the kids great feedback on their talking level an helps me assess the sound level in a more objective way. Money well spent."

"Not a fancy app, but was just what was needed to teach my small group of students about regulating their noise level. I have recommended to several parents and colleagues!"
