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.
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.
The developer does not collect ANY data from this app!
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.
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.
Very easy to use and well designed
I download this app and within 15 minutes it was for using it and fully understanding I had a couple of tech-support questions I emailed the company in Netherlands I believe and they answered within a day and they answered more than satisfactory with links and pictures and graphics. The application, the developers, and the tech-support are WONDERFUL!!! I can’t recommend this more highly — it’s the best dB sound meter that I have used. As I understand it if you buy one of the external microphones with your calibrated to the app and then you calibrate the dB Meter following their procedures, the results are legal, and from what I understand, admissible in court or other type of legal proceedings. Please don’t quote me on that part, but that’s my understanding. Thank you! Phil, Colorado
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.
I have used this app for a very long time now for the laeq functionality to find long term (30ish minute) average volume. I also spot check consistently to watch for short term exposure levels. The app is surprisingly close to my calibrated dB meter! Usually within .5 dBA, as long as the room volume is under approximately 95dBA. I foresee myself using this for a long time to gauge live music volumes.
Love this app
I use this app all the time when I go to concerts and I love it. It does exactly what I need it to do. My dad knows a lot about safety in the workplace and other environments so I like to show him how loud it is when I go to certain events. Little Bug: When swiping to delete and not letting go but swiping back as to cancel the action the app crashes. Just a little bug I found!
so much fun
this game is so much fun! I would give it 10 stars if I could. my high score is 132.2 dB. Let me know if anyone is able to beat it. this game is a family favorite and will be sure to have the entire group laughing. my family loves to play this game as we wait to be seated at restaurants. It is also a lot of fun to play on long car rides and flights!!
The best and only good sound meter app
Well made, well designed, free and without ads or other annoying BS. As or more accurate than the inexpensive handheld sound meter I have. The only feature I wish it had was the ability to auto save sessions - I often forget to press the save button and then it’s gone forever! Besides that, great job NIOSH.
From a real person with nothing to gain from this.
Used it and it made “correct seeming” readings it went up with noise and back down. I wouldn’t trust it for professional work(school). But this is FREE no subscription required before it starts. 100% recommend it Disclaimer: Original post written after 3 app starts and 20 min spent on app.
Play & Pause doesn’t seem to work
I can’t tell what the play or pause does as when I click on either one, the noise measurement continues to respond. Then, sometimes the app would freeze and not record any measurements whether I clicked on play or pause. I also gotten situations were the app is responding to sound and updating the metrics in the stat below but the main display where it displays the instantaneously levels just shows —.
Easy to use and free
Great app. Upon opening it provides instructions on use. It’s fairly simple with only a few options to choose from with no annoying ads of any kind. It was also the only app I’ve used that makes calibrating an add on mic easy and accurate. Great use of tax money.
The actual free one
Don’t bother downloading the other apps that come up in search. Almost all those require you to sign up with credit card before you can even use them. Garbage This app is by far the best and easiest to use. Don’t hesitate and just get this one.
