About this app

dB Aura is a decibel meter and sound level meter that measures the noise around you. Tap Start: the sound level in dB appears live on a clear gauge, with a curve that follows the noise second by second.

MEASURE NOISE IN REAL TIME
• Current sound level in decibels (dB)
• Minimum, maximum and energy average (Leq)
• Noise curve over the last 30, 60 or 120 seconds
• Pause, resume and finish a measurement in one tap
• Context label: whisper, conversation, busy street…
