dB Volume
DSP Mobile UG (haftungsbeschraenkt)
dB Volume measures environmental sound levels with a supported iPhone/iPad microphone setup.
What dB Volume does
dB Volume turns the iPhone into a simple sound-level meter with selectable weighting and response modes. Its current listing documents Leq and peak functions. The developer cautions that device-to-device microphone differences limit factory calibration; a reading is not proof of a certified measurement.
How it compares
Basic levels rather than a noise-exposure toolkit
dB Volume focuses on sound levels, Leq and peak readings. If you want to track noise exposure as well, NIOSH Sound Level Meter includes noise dose, while Decibel X offers a dosimeter and measurement history.

Complaints
- A large group of 2015–2016 reports describes no readings on iOS 9/iPhone 6 or 6S; later comments say it worked on some setups. All captured comments predate 2021, so they do not establish current-version operation.
- Some 2012–2015 reviewers object to an upgrade/promotion screen interrupting measurement. Current pricing or upgrade behavior cannot be inferred from those reports.
Mixed reports
- Historical reviewers often value the simple large meter for quick checks, while some question calibration or report differences from a reference meter. These user comparisons do not establish measured accuracy or suitability for hearing-protection decisions.
