Most mobile microphones are aligned to the human voice (300-3400Hz) and may limit measurement of extremely loud sounds (over 100dB). For professional-grade physics experiments or industrial safety compliance, we recommend using a certified industrial Sound Level Meter. However, for daily use, home measurement, and general noise detection, NoiseMeter provides highly reliable results. Protect your family's health and your hearing today.
