With dB Volume you turn your iPhone into a Sound Pressure Level (SPL) Meter. You can choose between the industry standard weighting curves and response times.

Use dB Volume for measuring environmental noises - it offers now Leq measurement!

dB Volume features:
- response time modes: impulse, slow, fast
- weighting functions: A B C Z (unweighted)
- peak hold function
- Leq measurement

We calibrated dB Volume as carefully as possible for all available devices. But: keep in mind, that due to manufacturing tolerances this calibration does not necessarily apply to your device – it’s still an iPhone, iPod touch or iPad and not a calibrated measuring instrument!

Optimized for iOS 9.3?

Ummm… You all are aware that we are on like iOS 11 point something now right?

Works, but could be more accurate.

The A, B, and C weightings are off. I am convinced that the meter is off just a tad bit. I use this on my iPhone 5S with iOS 10. Today I'm writing on March 29, 2017. So yes, it works but with some little improvements this app would be phenomenal.

Used to be great. Not so much anymore

This used to be a great little app. The last update killed this thing. I get no audio and no indication of a signal. Found another app since you've killed this this off... Don't waste your time.
