See subject. What would you recommend? There seems to be dozens of them in the Play Store.

Bottom line: get one that uses an external microphone. The iMM-6 from PE is a good way to go.

I'm not looking for excellent accuracy, just something that's reliable in repeated measurements. +/-2dBA accuracy is fine for this particular need.

Both of those links are refenced in this article about how to measure obnoxious noise from your neighbors: http://www.audiodevelopers.com/minne...measure-noise/
The background for that article is that Maryland has a noise law (like most states), but it is up to the county governments to enforce the law. However, Garrett County, where we have our cabin, doesn't enforce the law. As a result, you either need to sue your neighbors or else sue the County (writ of Mandamus). We did the first option, but we really should have done the second.Free Passive Speaker Designer Lite (PSD-Lite) -- http://www.audiodevelopers.com/Softw...Lite/setup.exeComment

That's unfortunate; Makes me glad my neighbours are a half mile away.

What level of SPL do you need it to handle? Ever seen a youtube phone video of a sound system that wasn't distorted? I haven't. The reason is the mic in most phones can only handle 90dB or so, external mics can go much higher. So just about any app will do but if you want to use if for anything beyond background sound levels a better mic is necessary.Originally posted by Brian Steele View Post

This technology is great these days. Back when I needed a SPL meter had to buy one at the shack. It has A & C weighted scales.
C weighted is full range. A weighted displays higher frequencies that can harm your hearing long term. Still works great after 20
years. Also has an analogue meter which is nice. Spl meters start at around $13. Accuracy 1.5 DB.Comment

He did say there were a bunch. What's special about that one?Originally posted by timothybrennan View PostFrancisComment

SPL Meter is built by the same team that created the other great professional audio and acoustics apps on the store, Studio Six Digital. Built on the engine of our more expensive "SPL" app, SPL Meter's filters and decay rates meet or exceed ANSI type 1. This app is not a toy or a game.Originally posted by fpitas View Post
*** FEATURES:
FILTERS -- A and C weighting filters are provided.
DECAY -- Choose ANSI Fast or Slow.
RANGES -- 40dB to 120dB in 9 ranges.Comment

I do my measuring on my laptop with HolmImpulse and a calibrated mic. It can only give a transfer function magnitude result. If you want an actual SPL you need to calibrate it with an SPL meter. I do so with a 1kHz test tone.Comment

Yeah, the SPL Meter App for Android device is one of my favorite, You can download it from Google Play Store. The best feature is Calibrate option – If you have a calibrated SPL meter or known loudness source, you can use this option to calibrate the meter. (However its still for Indication Only).
