Sound level meters are useful for anyone who wants to avoid exposing their ears to harmful noise levels, but who wants to spend hundreds of dollars on one?

dB Meter is free app which provides professional-quality measurement results, calibrated using an actual Nor140 high-precision decibel meter. With dB Meter, you can measure ambient noise levels, save your measurements and their locations, and share your measurements with others. dB Meter couples utility with stylish design and a polished user experience: a powerful tool in a sleek package, and at a tiny fraction of the cost of professional sound level meters.

(Please note that dB Meter Pro app is not a replacement for professional devices and should be used for personal purposes only.)

Recording with a photo for location?

DB meter is definitely a good app that recording noise. But for recording noise, the precision of location needs to be improved. Otherwise it is hard to become good evidence. Perhaps every recording can combine with one photo to prove its location? Just a suggestion.

Developer Response ,

It's a good idea. Thank you!

Thank you for sharing your feedback.
Please note that deleting an app does not also cancel any active subscription you may have to that app.

If, after downloading Decibel, you chose the free trial and did not cancel it before the trial expired, it will be automatically converted into an active subscription and you will be charged.

If you want to check if you have an active subscription to Decibel or any other app and cancel it, please use the official Apple guide available here: https://support.apple.com/en-us/HT202039. Alternatively, you can open the app, go to Settings, select “Manage subscriptions” and, in the new window, select “Cancel subscription”

I hope my reply helps clarify any issues and you continue to use and enjoy Decibel.
Wish you all the best!
