- SPL Meter with unmatched precision, weighting and Leq measurement

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 and not a calibrated measuring instrument!

What’s New

Version 3.0

- support for iOS 13
- improved graphics
- improved calibration

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.

Easy simple big meter

Easy simple big meter. Goes up and down with change in volume, useful in gauging volume on any number of things. In my quiet living room meter reading sits/starts at about 40, not sure this is accurate starting point but I can gauge louder spikes in various sounds from there. Plus heck its free!

Nice meter, but sensitivity is way off. The A weighting is 3db low, the B weighting is 10db low, the C weighting is 15db low. I checked with a calibrated Simpson 886 sound level meter. It would be nice if a calibration feature was included so that it could be adjusted to agree with a professional meter. With a C noise level of 50db, this meter says it's 35db.
