## What is dB Meter Pro?

dB Meter Pro turns your iPhone into a sound level meter you can trust. It measures the noise around you in real time, using A, C and Z weighting (dBA, dBC, dBZ) built to the IEC 61672 standard.

The app never records, stores or sends your audio. It only listens long enough to calculate a level, then shows you the result on one calm screen with live readings, a frequency spectrum, and plain-language comparisons to everyday sounds.

### App Store description

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

- 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

## dB Meter Pro, in detail

### How does dB Meter Pro measure sound without recording audio?

dB Meter Pro uses your iPhone’s microphone only to calculate a sound level in real time. The audio itself is never recorded, stored or sent anywhere, so the app can show you live readings without keeping a copy of what it hears.

This design lets you check noise levels at home, at work or anywhere else, with the same privacy you would expect from a simple measurement tool.

### What do the “MIN”, “AVG”, “MAX” and “PEAK” readings mean?

The main screen of dB Meter Pro shows a live level next to “MIN”, “AVG”, “MAX” and “PEAK”. “MIN” and “MAX” are the lowest and highest levels measured during your session, “AVG” is the average level over that time, and “PEAK” is the single highest instantaneous reading picked up by the microphone.

Alongside these numbers, a real-time frequency spectrum and plain-language comparisons, such as “normal conversation” or “city traffic”, help you put the reading in context.

### How does the noise-dose tracker help protect your hearing?

dB Meter Pro includes a noise-dose tracker that follows the NIOSH and OSHA standards for occupational noise exposure. It keeps a running estimate of your exposure and warns you before sound levels become risky, so you can step away or lower the volume in time.

dB Meter Pro is a measurement aid for everyday hearing-safety awareness. It is not a certified Class 1 or Class 2 instrument and does not diagnose or treat any condition.
