NIOSH sound level meter
I love the convenience of this app, and how simple it is to use.
I have protected my hearing since I was a child when I found out that some of my relatives were very hard of hearing because they had been exposed loud noises in their lives. I still jealously guard my hearing, as I have worn glasses since I was a kid and don’t want to lose a second sense.
When I am exposed to loud noises by people who don’t seem to care, or it doesn’t sound that loud to them because they have already damaged their hearing, it gives me an opportunity to show them that it is loud enough to damage hearing and they need to turn the volume down a bit for everyone’s sake, or it shows me that although I’m uncomfortable, it’s still in the safe zone, and I just put in my earplugs. Or if it’s someone like my husband who is hard of hearing from all his years in construction and not protecting his hearing and needs the volume up like that to hear it, I just hand him the headphones.
I pulled your app out to use it this time because all the hammering going on inside my house right now (a construction project inside my own home) is hurting both my ears and the dog’s, so I was checking to see how much damage is being done and are the dog and I safe without hearing protection.
Thanks!

Can save environmental noise data to Apple Health
Great app to use if you don't have an Apple Watch or can't afford one. It will keep the screen on and drain the battery, but I don't use my iPhone as my main phone. I use it as a portable media player and now also as a decibel meter at work. I run this app while I'm working --with the phone in my pocket, with the mic up and sticking out of my back pocket-- my warehouse job. I save the data to the Health app to make sure my job isn't causing me irreversible hearing damage over time.
I'll also run it in public places such as grocery stores, and in the car while driving.

Diray Acosta,
Doesn’t Work
I was using it to try out the free version and when I installed it and opened the app for the first time; it showed me readings that were very untrue like 120dB. I know this isn’t right because I was lying in my bed with no electronics on next to me or anything loud at all. I don’t know what the problem is since there’s so many positive comments but it no work :(
EDIT: I thought there could be a free version and a paid version but I guess I was wrong. This review is not for a different app by the way, it was just what the app was showing me. But I do not have a professional microphone attached to my iPad so if you want to say it was that I guess it could be 🤔 yet I doubt it. I will change my review to 4 stars because I am only testing this against 3 other decibal meters and not a profesional machine or a sound that is supposed to be at a specific level.

Me 1024,
Well done
I have been using this app for over a year and through several updates. It has always worked well and accurately. It has been a useful tool for monitoring the noise exposure and deciding where and when I need to wear earplugs. The only feature it lacks (in my opinion) is the ability to run as a background process with the phone asleep (similar to the way you can play music), which would allow to have the screen off and use less battery when monitoring for long periods of time. Aside from that personal preference, this app has been reliable and helpful. I would highly recommend it.
AcousticsProf,
The only truly free and most accurate decibel app
No ads, no in-app purchases, no hassle to upgrade every 10 seconds, fully-featured unlike the other top apps that entice you with a single feature but force you buy an upgrade to get the rest of the functionality of the app.
Developed for professional users who are serious about acoustics by the top hearing lab in the country, if not the world. I use a Larson-Davis 831 for my daily work and have compared many apps to my SLM and though I was always skeptical about apps, this one is the most accurate out there.

Fototico,
I wonder about it’s accuracy
I wonder about the accuracy of this and other apps. I compared the readings I was getting from this app in my iPhone 14 Pro Max and the readings from the Apple Watch. This app consistently kept showing noise levels to 5-7 bd louder than the watch. So I went online and ran a search to see of anyone had tested the accuracy of the Apple Watch’s noise meter. It appears that people tested the watch with a dedicated noise meter device, and it was off by like 2 or 3 tenths of a db. Pretty darn good if you ask me.
But to be fair, I compared the reading of two other apps and they also were all over the place. One showed reading about this app. Another between this app and the watch’s reading.

My preferred noise measurement app
As a researcher in the field I have been following the scientific literature on noise apps for the past five years and more. This one has been tested and reviewed and shown to perform with good accuracy. I have also worked with it in my own laboratory to verify its performance. It continues to be updated, the latest update including calibration for the iPhone SE and iPhone 12 series of phones. Thank you NIOSH for an excellent tool.
groundflax,
Seems accurate, but stops audio for some reason
I downloaded a couple other apps before this one and this was the first that have anywhere close to believable readings so I think it’s accurate.
However, when you open the app it stops whatever you are listening to on your phone! Which is bizarre bc this is supposed to help you measure the noise level around you and you can’t do that since it turns off a big source of noise first! So that’s very unfortunate and weird, but it’s a good app for other situations.

External Microphone not possible
I have tried now on multiple separate phones with the software freshly installed. I cannot get the program to recognize any external mics I plug-in to have better accuracy than the in accurate internal mic. I would like to put a mic and they can actually placed on a calibrator.
I’ve sent a message to the Company that has developed the software and I will be looking forward to hearing back how one can properly connect an external microphone to the software.
It is completely ineffective to use the internal Apple microphone so that is no option at all for any real use of this software.

smileitspaul,
Just what I need, nothing I don’t.
The app developers really deserve praise for creating a completely free app that doesn’t blast me with ads, beg me to upgrade, and generally distract me with BS when I try to use it. The interface is clean and easy to navigate. It seems very accurate, especially for what I need which is basically just comparing noise levels relative to one another. It never glitches or quits unexpectedly. I’ll stay loyal to this app, it is exactly what I needed.
