Checking a noisy restaurant, a concert, your AC or PC fans, road and traffic noise, a snoring partner, a baby's room, a workplace or machine shop, or a neighbour's music?

Quiet library ~30–40 dB · normal conversation ~60 dB · busy traffic ~70–80 dB · lawn mower ~90 dB · nightclub ~100 dB · rock concert ~110 dB. Sono labels the live reading against everyday sources so the numbers actually mean something. Great For • Checking whether a venue, restaurant or workplace is too loud • Settling neighbour noise disputes • Calibrating speakers, home theatre and audio gear • Measuring appliances, fans, engines and machinery • Anyone curious how loud their world really is A Note on Accuracy: Phone microphones are tuned for voice and can clip at very high volumes, so readings are approximate. Sono is a reference tool and is not a replacement for a certified sound level meter (SLM). Use the calibration offset to align Sono with a known reference for more reliable results. Sono is not a medical device and does not diagnose, treat, cure, or prevent any medical condition. Not a certified sound level meter, for reference only. Sono: the simple, offline decibel meter.
