Sound Meter - Decibel Meter

Sound Meter keeps a calm, dated record of the noise you live with: footsteps and thumping from upstairs, music through the wall, traffic late at night.

Instead of a bare number, every reading is compared with a reference you choose, for the time of day.

HOW IT WORKS
• Listen – the level is averaged minute by minute and shown next to your day or night limit.
• Record when it happens – one tap, from any screen.
• Pre-roll – the seconds before you tap Record are kept, so a noise that already happened is still in the recording (5 s free, 30 s with Pro)
• Tag it – footsteps, thumping, furniture, music or TV, voices, pipes, construction, traffic – and add a note.

A CLEAR REFERENCE
• The Korean apartment noise standard is built in: 1-minute averages, day 39 / night 34 dB(A), peaks counted only at 3 or more per hour.
• Or set your own day and night limits and your night hours.
• Each entry shows whether it was within, close to or over the limit, and by how much.

YOUR NOISE NOTEBOOK
• Entries grouped night by night, with time, length, 1-minute average, maximum, tags and note.
• Filter by over the limit, night or tag, and search your notes.
• Keep the audio clip, or turn audio off.

A REPORT YOU CAN SHARE
• Choose a date range for a summary, per-night counts and the entries over your reference.
• Share it as text or export CSV for your building manager, landlord or a mediator.
• Patterns show the loudest hours and weekdays, and the sounds that come up most.

HONEST ABOUT ITS LIMITS
• Check your phone's quiet floor. Readings it can't measure reliably are marked, not judged.
• A phone is not a certified sound level meter; results vary by device and placement.
• Reference values are for comparison only and are not legal advice.

ALSO INCLUDED
• dBA / dBC / dBZ, Fast / Slow and calibration
• Octave spectrum and noise exposure under "More detail"
• A dark theme made for night use, and tablet layouts
• Sound levels and recordings stay on your phone unless you share them
• Free with banner ads. Sound Meter Pro removes ads and keeps the 30 seconds before you tap Record: yearly subscription with a 7-day free trial for new subscribers, or a one-time lifetime purchase
• The subscription renews automatically unless cancelled at least 24 hours before the end of the period; manage it in your account settings
