Decibel App DESCRIPTION

Decibel Meter Pro is full of features sound level meter with exclusive accuracy of measurements and integrated Spectrum Analyzer. Calibrated with professional dB meter.

The world is a noisy place: cars, power tools, crowds, machinery, and other common sources produce amounts of noise that can, with continued exposure, lead to permanent hearing loss. Sound level meters are useful for anyone who wants to avoid exposing their ears to harmful noise levels, but who wants to spend hundreds of dollars on one?

dB Meter is free app which provides professional-quality measurement results, calibrated using an actual Nor140 high-precision decibel meter. With dB Meter, you can measure ambient noise levels, save your measurements and their locations, and share your measurements with others. dB Meter couples utility with stylish design and a polished user experience: a powerful tool in a sleek package, and at a tiny fraction of the cost of professional sound level meters.

(Please note that dB Meter Pro app is not a replacement for professional devices and should be used for personal purposes only.)

This tool is absolutely free. Decibel Meter turns your iPhone, iPad and iPod touch into a professional accurate sound meter, precisely measures the sound pressure level all around you. This extremely useful tool. Have you wondered how quiet is your room or how loud is a rock concert or sport event? Decibel Meter will help you answer all those right now. A decibel meter is a device which measures sound pressure to determine how intense sounds are, measuring in decibels. Decibels are a logarithmic scale based on the sensitivity of the human ear. Prolonged exposure to sounds over 85 decibels can lead to hearing loss, making measurement of decibel levels important for people who work in noisy environments so that they know when they need to protect their ears. For a frame of reference, normal conversation occurs between around 40 and 60 decibels, depending on who is talking. A firecracker is about 140 decibels, and a jackhammer runs at around 100 decibels. Musicians, mechanics, construction workers, and other people who work in loud environments can endanger their hearing, especially if..

App REVIEWS

ndnslfoh..

This is in no way free. It immediately tries to make you pay like $30 after you download lol- false advertising, should be illegal but of course apple won’t stop them so what can you do. Good luck getting accidentally charged by this “free” app that probably has thousands of fake 5 star reviews.

Jcc0612

So, I deleted it...

jim79c

In a quiet room it shows 45db, an AC unit in our motorhome kicks on and is really loud it shows 57db. I’m sure it’s the microphone in the phone has horrible frequency response.

Cereal

I compared basic measurement results to a calibrated, class 1 sound level meter (which costs thousands of dollars). A-weighted measurements are reasonably accurate, but unweighted (“Z” weighting) measurements are completely invalid.

IIRick

There is no way I’m paying a subscription for such a simple utility. No idea how to even do a one time payment. And then it’s not clear which features you’d even get. App has way too many in app purchase options. Agree with others that this is all very shady.

amblepat..

Kudos to the UI/UX team. Masterful work. d. Meter is a perfect blend of commercial utility and recreational use.

Spycraft..

If you must monitor sound levels, this app is a must and the fact it fits in your pocket - priceless….

Barefoot

Not only does this app seem to be quite accurate, but I used it to test my hearing and later had a doctor test my hearing. The results were similar, so now I can monitor my hearing as I age and as often as I want. Plus when you check out how loud your environment is you are alerted to excess noise- you might be surprised at the sound levels.

Not free. Trial only. Didn’t even try it out. Deleted immediately

Definiti..

Can’t use without signing up for a trial. Delete it immediately

I’m using the latest OS and the app loads, allows you to click but as soon as you need to click agree to terms it locks up. Also it’s not a one time purchase but a paid subscription.

Good free app (the developer informed me on my last review when I mentioned the app does not let you use it without paying, so I updated my review. Apologies and thank you for your work.)

This app won’t let me delete it or hit a cancel button. Not a good app!!

I’m a musician. My personal hearing, equipment, & spaces that I record/stream from make great use of this app. I don’t normally write these, but figured these guys deserved it bc the product is that good. 👍👍👍

ehollawa..

This is a great app, and I keep seeing reviews by really stupid people saying you have to pay to use it. You don’t. All you have to do is stop being lazy and look at the screen for more than half a second. Tap the x in the top corner of the initial pro offer and it takes you to the app. It angers me when developers put a lot of time and effort into a good product like this and then get bad reviews because people can’t be bothered to use their brains every once in awhile.
