Sound level meter with live dB, hearing safety bands & sound direction radar.
SoundRadar is a beautiful, modern sound level meter that answers a question no other meter does: not just HOW LOUD a sound is, but WHERE it's coming from. Point your phone at the noise and watch a live, real-time decibel (dB) meter with a smooth rolling graph, PEAK / MIN / AVG readings, and a clipping indicator. Then let the radar do something unique - using your phone's stereo mics, SoundRadar estimates the DIRECTION the sound is coming from (Left/Right, and Up/Down on supported devices) with a confidence level and a live radar visual. Honest note: phone mics sit close together, so direction is a rough estimate to point you the right way - not lab-grade localization. We'd rather tell you the truth than over-promise. 🔒 PRIVACY FIRST Your audio is analyzed on-device, in real time, and is NEVER recorded, stored, or transmitted. The mic is only ever a live meter - nothing leaves your phone. 🎧 KNOW IF IT'S SAFE A friendly 4-band safety classifier reads every moment in plain language - SAFE, MODERATE, LOUD or DANGEROUS - with clear warnings when levels climb above 100 dB. Perfect for concerts, gyms, clubs, restaurants, a baby's room, a noisy workshop, or a disruptive neighbor. ✨ WHAT YOU GET • Real-time sound level meter with live dB and a rolling graph • Peak, minimum and average dB for every session • Sound DIRECTION radar with confidence level (stereo mics) • 4-band hearing-safety classifier + dangerous-level alerts • Clipping indicator so you know when it's truly loud • Session HISTORY saved locally: date, avg/peak/min dB, duration and safety badge, with summary stats - delete one or clear all • Calibration offset to match a reference meter for closer readings • Keep-screen-on while measuring • Light, dark and system themes • Friendly onboarding to get your first reading right 📍 GREAT FOR • Concerts, festivals, clubs and earbuds - protect your hearing • Finding a rattle, buzz or hum - which side is it on? • Home, office, classroom or street ambient-noise checks • Documenting noisy neighbors with timestamped history • Anyone curious "how loud is this, really?" ⚠️ HONEST ABOUT ACCURACY SoundRadar gives estimated dB readings from your phone's microphone. Phone mics vary, so this is an awareness tool - not a medical, OSHA, or professionally certified measurement device. Use the calibration offset to get closer to a reference meter.
