Decibel X App DESCRIPTION

Decibel X” is one of very few noise meter apps on the market that has highly reliable, pre-calibrated measurements and supports dBA, dBC. It turns your iOS device into a professional sound level meter, precisely measures the sound pressure level (SPL) all around you. This extremely useful and beautiful tool will not only be a great tool for many uses but also bring you a lot of fun. Have you wondered how quiet is your room or how loud is a rock concert or sport event? “Decibel X” will help you answer all of those.

WHAT MAKE IT GREAT AND STAND OUT FROM OTHER APPS:

– Trusted accuracy: the app is tested and pre calibrated for all Apple devices. The precision is matching with real SPL devices
– Apple Watch support: see noise level right from your wrist
– Health App integration: export noise levels directly into Health app
– Frequency weighting filters: ITU-R 468, A, B, C, Z
– Powerful, smart history data management:
+ Recording data can be saved into a list of history records for future access and analysis
+ Each record can be exported as hi-res PNG graph or CSV text via sharing services
+ iCloud support which synchronize all history records across your Apple devices
+ Fullscreen mode to give overview the whole history of an record
– Dosimeter with NIOSH, OSHA standards
– Powerful calibration: Linear, Octave 1/1, 1/3, Load/save profile
– FFT and BAR graphs to display real time FFT. Those are very useful for frequency analysis and musical tests. Real time predominant frequency is also displayed.
– InstaDecibel to capture your dB report overlaid on photos and easily shared via popular social networks (Facebook, Instagram, Messages, etc.).
– Support Live Activity, Dynamic Island
– Support both Portrait and Landscape layouts
– Beautiful, intuitive and carefully crafted UI design. Themes: LIGHT, DARK and CLASSIC

OTHER GREAT FEATURES:

– Standard time weightings (Response Time): SLOW (500 milliseconds), FAST (200 milliseconds) AND IMPULSE (50 milliseconds)
– MIC Gain Offset from -50 dB to 50 dB
– Standard measurement range from 30 dBA up to 130 dBA
– HISTO graph for plotted history of the recorded values
– WAVE graph with 2 display modes: Rolling & Buffer
– SPECTROGRAPH
– Real time scale level chart
– Display Current, Average/Leq, and Max values with both nice and clear digital and analog layouts
– Quick reference text to help you compare with real-life examples

NOTES:

– Please do not expect a quiet room reading will be 0 dBA. The range 30-130 dBA is the standard usable range and an average quiet room will be about 30 dBA.
– Although all devices are pre-calibrated, custom calibration is suggested for serious purposes requiring higher precision and accuracy. You will need a real external device or calibrated sound meter as a reference, then adjust the trimming calibration until the reading matches with the reference.

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..

Platinum..

Limited and expensive. Worthless

R6Kriss

Don’t work, idk how people are saying all this good stuff. I did exactly what the app said didn’t pick anything up, my neighbor plays music super loud, my regular phone doesn’t pick any noise up what so ever so I thought a decibel meter would not only read the levels but record what normal devices can’t pick up.

sandtv

This is not a free app. It’s a trial only and requires a monthly fee. Misleading

okraland

I bought the subscription to record video while measuring the noise levels but I’m still limited to few seconds of recorded video.. this rendered the app to be useless to me.. Update: Steps to reproduce: 1. Open the app 2. Tap the camera in the app 3. Switch to video 4. Tab the red record button 5. The video recording stops after a few scones. recording full videos seems to be limited to the paid version, which I paid for already.

threepac..

SAAS is out of control. It’s absurd and greedy to charge a recurring subscription for a simple utility app. It could be the best sound meter in the App Store but it’s zero stars if it requires recurring payments to use.

TheWorst..

I tried to close the app the instant the subscription screen came up, it wouldn’t let me. When I clicked the ‘X’ it continued through, that’s some dark coding right there.

My

I purchased it, but cannot get it to open or to work. It is very, very frustrating.

gderm

App works fine but I opened it after not using for a while and it thanked me for my “purchase.” What? Unless I totally missed something all I did was open the app and suddenly was charged $4.99…pretty annoying for obvious reasons.

Awolfnot..

Doesn’t work, just looks good, used on IPhone 13pro and it was a no go, it will not pick up any variation no matter what you want reading you want to take, it’s an eye candy app only.

EbitdaMo..

Too much

McMailMa..

Trying to get the decibel read on this noisy ps5 fan. has my ambient DB in a quiet room at night at 30. hold it up to the noisy fan it jumped 50… But if I blow lightly on on my phones screen from my normal viewing distance it it goes to 90. so… in my opinion… It’s either reading wrong, or it does not pick up the frequency of the loud fan. or like I said, maybe I just don’t understand how it works.

BarTekte..

No need to pay.

why

This is not a free app. It is a “free” 3-day trial of a monthly charged app. Hardly “in-app microtransactions” if they’re required for use.

Mooney

I just downloaded this app thinking it was a free iPhone app. Then I saw it was free for three days and then there was a subscription charge. I didn’t want to pay for it and there’s no way to cancel it until I remember to go back on to cancel it three days from now after I have already paid for a month. It’s a bait and switch scheme!

Poopy

If you are then the monthly fee isn’t worth the cost. I can see one time but not monthly. Update: The developer answered my initial comments, which is good they are monitoring to address issues. They said the Pro version is available at a price of $40 I assume one time but I didn't look. I don’t think they understood that as a casual user that I am, I don’t think it’s worth monthly or any fee. I was looking for a decibel app for a one time if less than 5 uses. Now for those who wish to measure sound in a daily basis this may work for them.

Needwing..

I woldent recommend this app

danielle

Then they charge out the yang for free stuff. Actually they charge you first then tell you that is cost $5 per month

icantbel..

It’s school

TerrorCr..

You can’t actually try it without paying. Sure you can cancel before the three days are up, but who actually remembers to do that? Not worth the chance of forgetting, rather just try to find something else. Gets a one star because it says its free but this makes it not free. #itISatrap
