Probably as accurate as my old Radio Shack meter. Sound level perception is highly subjective. So a meter is useful.
You never know...although it would be interesting to compare it to a known quality meter.
It wasn't that long ago the "talking heads" surmised that a Leica Disto would be the only accurate laser measure...now there are probably 2 dozen.
Acoustic calibrators are used to check the accuracy of db meters. Also not too expensive. But how do you calibrate the calibrators? [big grin]

As an aside, I learned that accuracy may not be what we aspire to. I bought a pricy “reference grade” set of earbuds. It came with the results of the testing that showed the actual sound levels as a black line and the reproduction as a blue line on a linear graph. If the testing is to be believed (and I do believe them), then they should sound great.
But we (the editorial “we”) have been bombarded with bass-heavy music for so long, that accurate reproduction sounds slightly tinny. Though I would note that it does an exceptional job of reproducing voices. So I rarely use the reference grade earbuds, favoring the triple driver earbuds with the over-boosted bass. Accuracy be damned.
