The "SPLnFFT" app is pretty good for the iOS platform
Are dB meters on smartphones accurate?
Hi, All. first post here. I installed a dB meter app on my phone that I use the when I go to small local shows. It's just to satisfy my curiosity, really. I was wondering how a phone app compares to "real" dB meters. Do the commercial ones have to be certified and calibrated? Have any of you compared both side by side?
Just wondering.😀

depends on what you're trying to do. Just a general idea of sound levels in your listening space?...then yes, they get you there within a dB or so. Are you seeking workplace exposure compliance under OSHA? Then no, you need a proper noise dosimeter that meets American National Standards Institute (ANSI) Standard S1.4-1971 (R1976) or S1.4-1983, "Specifications for Sound Level Meters."

You can get a calibrated mic for a smartphone for about $22: https://amzn.to/2LBaQKY You need an app like AudioTools which accepts a calibration file. Best, E |
All about the mic isn't it? calibration? Your finger half way over the speaker, position, you know all the stuff you have to do if your interested in the data being accurate and in turn more useful. If you just want to know how loud it is. It will give you an idea about SPLs though, how accurate? good question.. Regards |
