Measure the sound of your life. Then share it.

dB turns your iOS device into a simple sound level meter. With it, you can tag the moments of your life -- the big game, standing on a mountain peak, or your best friend's wedding -- in a unique, new way. Getting started is as simple as tapping the app icon in the Home Screen to launch the app. Easily tag your moment with the current sound level, and share it with your friends and family, or the world, via email or Twitter.

dB provides default sensitivities for the built-in and headset microphones.

- Measure average, max, and peak sound levels (dB employs standard fast time-exponential weighting and no frequency weighting).
- Share your dB's via photos, graphs, email, or Twitter.
- dB can measure peak sound levels of up to approximately 130 dB (peak levels are device/microphone dependent).

NOTE: dB has not been shown to meet ANSI or IEC standards for sound level meters.

Ratings and Reviews

Doesn't do much. No graph


Shows only max and peak. Elapsed time.

Really Great App


What a steal for a sound level meter! Using the headset mic on my 1st gen iPhone, it measured within 1 dB of the sound level meter at our lab for white noise and periodic signals. The photo tagging capability is a smart, attractive way to present a lot of information about a quick measurement and a unique, fun way to share life events over the web. Twitter integration is smooth. The user interface is slick, just like on other Faber apps. Thanks Faber Acoustical.

Nice simple app

I like this app, because it allows me to save a photo of the event or location along with the measurement very easily. Since other measurements I have made use A weighting, it's a little annoying that this is not an option.
