Decibels Sound Level Meter

Sound Level Meter is an iOS tool for everyday environmental noise measurement—see levels in the field, keep a log, and share a polished Pro report when you need one.

Features • Live A-weighted sound level with Fast / Slow time weighting • Session stats: energy-style average (LAeq) and peak (LAmax-style) • Acoustic calibration offset to align with a reference source • History with custom titles and optional location notes • Export CSV / JSON and Pro PDF measurement reports • Education: hearing & decibels, typical noise level ranges

Good for Home and office background noise, street/neighbor logging, DIY checks around renovations or equipment, quick reference notes and sharing.

Disclaimer Readings are estimated from the phone microphone and software. Results vary with device, mic sensitivity, handling, wind, reflections, and calibration. Outputs are for personal reference, logging, and sharing only—not legal metrology, certified lab reports, or compliance determinations. Use a calibrated standard sound level meter and qualified professionals when precision matters.
