Description
Want to know what noise level is around you? in the restaurant? in the train? in the office? This app will show you with precision & style.
Features:
- Smooth analog display of dB(A)
- Take photo with sound level display
- Share, print, and store sound level photos
Extra Features (with purchase):
- Select frequency weightings A, C, and Z

This app uses the internal microphone to estimate the sound pressure level in decibels (dB SPL).
Examples:
- quiet bedroom at night: 30 dB
- average home: 50 dB
- vacuum cleaner, 1m away: 70 dB
- jet aircraft, 50 m away: 140 dB
What’s New
Version 3.5.2
Thank you for using Decibels. This version fixes a bug that in some cases prevented the microphone from being activated when the app was reopened.
Ratings and Reviews
Excellent
Nice and simple. The free version should be good enough for most users. I have it installed on my Watch for easy access when I’m working in a noisy environment and it gives an alert if sound levels reach an alarming level. Brilliant!
Quite good
Easy to use and analog meter is an effective method for this purpose.
However the strip recording is odd: nothing intuitive about this!
It seems you can’t stop it, and there is no way to show when the record was made. The top left and right labels are virtually unreadable (for SELECT and DONE), and I don’t see how to annotate them. Am I operating it incorrectly I wonder?
Developer Response ,
Thanks for your review and comments!
The strip chart recorder is meant to be as intuitive as possible, but obviously needs some improvement / instructions. Thanks for pointing at this.
Some quick tips for using it:
- It continuously records the sound level as long as it is visible on screen.
- Tap on the left side (where the strip comes out) to start a fresh strip.
- The (start-) date and time is printed on the left side of each strip.
- Swipe over a strip on the stack to delete it.
- Tap the stack to display all recorded strips.
- Two-finger swipe over the list to select multiple strips for sharing or deleting.
- Tap a strip in the list to enlarge it, then tap somewhere on it to add a short annotation.
There is obviously a bug with the visibility of some buttons in dark mode. Sorry for this - will get fixed.
Works well and it’s free
The app does exactly what you expect and it costs nothing for the basic db meter.
I note also that it responds to ultrasonic frequencies (for example a pest repellent device) and shows the decibels accordingly.
