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!
