## What is Sound Meter?

Sound Meter turns your phone into a sound level meter: it measures noise in decibels, keeps the readings, and turns them into a document.

■ Measurement
· 1-min Leq · Lmax · Min/Avg/Max (dB)
· Live waveform
· Microphone calibration — Offset against a reference meter
· Sample rate — Readings per second

■ History
· Leq (1 min) · vs baseline · Samples
· View raw data · Export CSV
· Save audio while measuring — Keep an m4a for playback and evidence

■ Noise Report
· Baseline comparison
· Korean apartment baseline (reference) / WHO reference lines / No baseline
· Daytime / Night

■ Noise measurement record report
· A PDF with timestamps, statistics and the baseline comparison
· These readings come from a smartphone microphone and do not replace a certified sound level meter. The calibration offset applied to each session is listed alongside it. This report provides no legal assessment; an official determination is only possible through measurement under the applicable statutory method.

Recordings stay on this device and are never uploaded.
