Decibels: dB Sound Level Meter

Analyze audio with style

Features & Capabilities

Decibels: dB Sound Level Meter provides a smooth analog display of dB(A) to help you gauge real-world noise quickly and stylishly. It can capture photos that embed the current sound level, then share, print, or store those images for later reference.

Premium features (with purchase) unlock frequency weightings A, C, and Z, plus strip-chart recording, annotation, and easy sharing. The app uses your device microphone to estimate sound pressure level (dB SPL) and includes practical examples (e.g., quiet bedroom around 30 dB, vacuum at 1 m around 70 dB) to contextualize readings.

User Reviews

Reviewers largely praise Decibels for its chart recorder, weighting options, and clean, quick interface, with many long-time users relying on it for everyday noise checks. The app’s combinations of a visible strip-chart display and A/C/Z weightings are frequently cited as major strengths. However, several reviewers report reliability problems (crashes or non-functioning), and note that measurements can vary with environment and are not a substitute for a true calibration. Some users also request more advanced features (peak/average, timestamps, GPS, landscape orientation) to reach a lab-grade experience.
Pros
  • Chart recorder/strip chart feature is a standout and widely praised.
  • Weighting options (A, C, and Z) are available and valued.
  • Fast, simple, and easy-to-use interface for quick checks.
  • Longstanding usefulness for daily noise checks and documentation.
Cons
  • Frequent reliability issues: app crashes or fails to run, making it unusable for some users.
  • Inconsistent/less-than-perfect accuracy: measurements can vary by room/setup and are not a guaranteed reference.

I like the old-school chart recorder thingy and the ability to use different weighting for the sound. Great for audio nerds

Exactly what it should be but I wonder why it asks for Camera access? Big thanks to developer for keeping this going.
