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 - Record decibels on beautiful strip charts - Annotate the strip charts - Share, print, and store the strip charts 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

They finally got it Calibrated.

I’ve been using Decibels for years having found the chart recorder extremely useful, however it always read dB a little higher than it really was. The last update corrected that and it now has correct readings. They also added different weighting settings A,C andZ. The basic meter is great and I recommend getting the options as it makes the best meter using chart recorders.

Good enough I guess

Every place you check, the approximate dB SPL of various sounds is a bit different. For example, other reviewers claim a quiet room is ~40dB, but various websites online say it’s 30 or even 20dB. My room at night measures 36dB. Similarly, conversation at 1m away is around 40-60dB, so I stood 1m away and spoke quietly, quieter than I would in a normal conversation in a quiet room (and I’m not a loud speaker). The app measured ~70dB. I guess I should just automatically reduce any measurement by ~5-10dB. Good enough if absolute accuracy isn’t a must, I guess. 4 stars, since I don’t have a good decibel meter to compare against.

Thank you for your review. I think part of the confusion are the different weighting schemes that may be used. This app measures raw SPL (no weighting) whereas most people seem to expect an A-weighting (db(A)). A-weighting makes the measurement less sensitive to low frequencies which results in a lower value in many cases. I'm planning to switch to dB(A) in the next version.

It’s a fun little app

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

I’ve used this app for years, and have found it quite useful, without distracting bells and whistles. I’ve also corresponded with the developer, and found that the weighting (which is not evident) is broadband.Some of the features of a lab meter would be nice to have, like switchable A- or C-weighting, or averaging vs instantaneous readings. But the app is quick and easy as it is, and ads do not intrude.

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.
