- People checking room, workplace, concert, or neighbor noise
- Worth noticing
- The page warns that phone microphones may distort above roughly 100–110 dB, and estimates quiet-room calibration at about 5 dB.
Field notes
After microphone permission, the interface exposes microphone selection, A/C/Z frequency weighting, fast/slow response, and pause/reset controls. Its quiet-room setup asks for five seconds of silence and assigns that room a 35 dB reading; a separate fine-adjustment option lets users match a trusted meter. The page says phone microphones may distort above roughly 100–110 dB and Bluetooth headset microphones filter sound heavily, so it points readers needing dependable work or complaint measurements toward a handheld Class 2 meter.
