dB Meter Pro vs Vgent工业声纹

dB Meter Pro turns your iPhone into a precise, private sound level meter. Measure the noise around you in real time — accurately, beautifully, and without ever recording your audio. WHY dB METER PRO • Accurate by design — A, C and Z weighting (dBA/dBC/dBZ) to the IEC 61672 standard, verified by automated tests. • Truly private — the microphone is used only to measure. Audio is never recorded, stored or sent. • One calm screen — live level with MIN, AVG, MAX and PEAK, a real-time frequency spectrum, and plain-language comparisons like "normal conversation" or "city traffic". • Protect your hearing — a noise-dose tracker following NIOSH and OSHA standards warns you before sound becomes risky. • Per-device calibration — fine-tune to a reference for trustworthy readings on your exact iPhone. PRO • Octave-band spectrum analyzer • Trends and full history, with CSV and PDF export • iCloud sync, widgets and Live Activity PERFECT FOR home and office noise, concerts, workshops, sleep environments and hearing-safety awareness. dB Meter Pro is a measurement aid for everyday awareness, not a certified Class 1/2 instrument. SUBSCRIPTION Pro is available monthly or yearly, or as a one-time lifetime purchase; the yearly plan includes a free trial. Payment is charged to your Apple Account and renews automatically unless cancelled at least 24 hours before the end of the period. Manage or cancel anytime in your Apple Account settings.
