Volume Meter provides a simple, fun way to measure audio volumes in your environment. The app shows the approximate dB (decibel) level, also known as Sound Pressure Level (SPL). It also includes a secondary meter to show the decibel peaks.

This particular decibel meter sports a vertical display with the English interpretation built into the main interface.

This app is intended for personal use only. For industrial use dB/SPL measurements, you should buy a real sound meter from your local electronics store. The app provides relative, approximate values only.

Weve included some useful statistics about the measured volumes, including Average, Peak, Peak Hold, current dB level, maximum, and minimum values. These can all be quickly reset by tapping the Reset button, or they can be "frozen" by tapping Start/Stop.

If you wish to use an external microphone, or if you find that the dB reading is a bit off when compared with traditional analog SPL meters, you can calibrate the app using the Configuration screen. For example, a hyper-sensitive microphone might give you a dB value that is too high, so youd add a negative Trim value to the dB reading to adjust. Calibration settings ("Trim") are saved internally in the app.

To adjust the calibration, tap the "Configure" button, and then adjust the value based on whether you are using an internal microphone (iPhone users) or an external microphone (iPod Touch users).

Please note that this application requires an external microphone for use with the iPod Touch.

An approximate guide to decibel level safety:

150-160 = Eardrum rupture

140 = Aircraft carrier deck.

130 = Jet take-off (100 meters), gun blast at close range.

120 = Human pain threshold, loud rock concert.

110 = Serious hearing damage if sustained for more than 1 hour.

100 = Serious hearing damage if sustained for more than 8 hours.

90 = Likely hearing damage if sustained for more than 8 hours.

80 = Potential but unlikely hearing damage if sustained for more than 8 hours.

70 = Just annoying, but probably safe.

60 = Typical conversational volume.

50 = A quiet, library conversation.

40 = A whisper.

30 = Barely audible sound.

20 = Threshold of human hearing.

Latest reviews of Volume Meter app for iPhone and iPad

200.5 dB?!
Theres something seriously wrong with this app or my PA. On my other meters I was running 85 dBA and this app told me I was running between 65 dB and 200 dB with an average of 150 dB.
Doesnt work
I used this app at a concert where the music was so loud the seats were shaking. This app measured the volume as annoying at the highest. Clearly it does not work.
