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

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.
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.
Working with iOS 9.3!!
It works beautifully! Use this for voice exercises to make sure I'm loud enough. Best program out there!
