SoundGaugeNoise Exposure & dB Meter

SoundGauge turns your iPhone into a real-time dB(A) sound level meter that also tells you how long that noise is safe to listen to. Point it at any room — a concert, a workshop, a busy office — and see the live reading, a plain-English context label, and your running average and peak.

Most decibel apps stop at the number. SoundGauge adds the part that matters for your ears: a safe-listening countdown based on the NIOSH 85 dB / 8-hour recommended exposure limit, so a quick glance tells you whether you're fine for hours or should step out soon.

WHAT MAKES SOUNDGAUGE DIFFERENT

• Live dB(A) sound level meter that updates in real time from the microphone.
• Safe-listening countdown based on the NIOSH 85 dB / 8-hour recommended exposure limit.
• Running average (LEQ) and peak for each session, with plain-English context labels — quiet room, city traffic, live concert.
• Timed exposure sessions with each session's percent of your safe daily noise dose (Pro).
• Full exposure history you can review anytime, plus CSV export for records or your audiologist (Pro).

SoundGauge is free, with unlimited live dB(A) readings, safe-listening time, and the current session's running average and peak. SoundGauge Pro is a one-time purchase — yours forever — that adds timed exposure sessions with daily dose percent, full history, and CSV export.
