User Reviews for Decibels

Fails at high end

At a NASCAR race at Dover it registered 90 when the green flag dropped. We were at the end of the straightaway just before turn 1. The cars came roaring; we were less than 25 meters from the track and the decibel level supposedly only increased to 95. If you’ve ever been that close to a start or restart you know the decibel level is well over a hundred. With head phones off and screaming in your neighbor’s face you cannot hear a word they are screaming!

Recorder does not work

While the free app works, do not waste your money. The strip chart recorder does not work

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.

Elegant and Simple

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.

Pretty accurate and free!

This app seems to be pretty accurate. I compared it with my Radio Shack meter and it reads within a few db. Only change I would like to see is a digital readout in addition to the analog one. I think a lot of the negative reviews are from people that don't understand how sol meters work... Even in a room you think is "silent" a meter will still read 30-40db...that's just the way it is...

Great. And free!

Those of you silly folks who gave this app one or two stars need to google how decibels work and what sounds are measured at. For instance a whisper is 30 db. Normal conversation is around 60 to 80 db. Sounds shouldn't be more than 85db to protect your hearing. This app runs pretty close to accurate. It's gets five stars from me because it's free and looks nice! Worth the space on your device.

Works great

Simple. The strips are cool.

It works, it's free, you can't lose

I am not sure of the actual accuracy; however, it is relatively accurate. What I mean is that a normal room with an air conditioner running is about 40 db, add a conversation across the room and it goes up 10 db or so. Some of the other reviewers have no idea what the decibel meter is supposed to do or how decibels are reported. One guy claims a quiet room should be 0db and rates the app poorly since it was registering 40db in a "quiet room". Also, those complaining about the meter not inverting, you don't need to "point" the microphone at the source of the noise. If you can hear the noise, so can the microphone. Look, if you are looking for an exact db meter for some engineering or legal reason, go get a real db meter for $60 or more. If you are somewhere and you find yourself having difficulty communicating with someone across the table, reach down and try the app to get a general idea of how loud it is where you are.

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.

Amusing (beta version?)

I know it's not accurate but it's fun to find out the approximate decibel level of the room you are in (apparently my fan is a constant 50dB.I might have downloaded a beta version though as there weren't any obtrusive adverts, nor other information, even about the author (not a complaint, just an observation). :)

Description

Want to know what noise level is around you? in the restaurant? in the train?

in the office? This app will show you. +++++ Thank you for the nice comments +++++ 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
