What SONARA Measures

Real-Time Decibel Meter

Uses your phone's microphone to measure sound pressure levels in dB. Live gauge updates continuously as sound changes around you.

Sound Level Classification

Automatically classifies noise levels — quiet, moderate, loud, very loud, or dangerous — with colour-coded badges so you know at a glance.

Min / Max / Average

Tracks minimum, maximum, and average decibel readings across your measurement session. Reset any time to start fresh.

Measurement History

Save readings with timestamps. Review past measurements to compare noise levels across different locations or times.

Reference Chart

Built-in sound level reference guide. Compare everyday sounds — whispering, traffic, concerts, jet engines — to your readings.

100% Offline & Private

All processing happens on your device. Audio is never recorded or transmitted. No account, no tracking, no ads.
