User Reviews for Decibel X:dB Sound Level Meter

Pleasantly surprised

I have a hand held sound pressure level (spl) meter, which I pull batteries out of between each use as it could be months in between uses. I’ve shared with flight attendants, construction workers, etc when the issue of noise in work environment came up. They were quite surprised something so capable of providing real time information was available. One suggestion I have is to identify what weighting scales, A, B and C are each utilized. Perhaps provide explanation of all and access to one within basic service. Want option to use/change among others and that might be offered through a higher tier (chargeable) offering. Might be interesting to know the frequency range (cycles) as well.

My usage of the app

Provided the app is calibrated properly when you set it up, it’s pretty accurate in isolated areas like calibrating a turn table or checking a receiver for accuracy. However, a bunch of unrelated sounds events taking place at the same time throws the app off. Instead of giving you an average for the space you’re in, it just fluctuates based on individual sounds it picks up. For example, I value my hearing because I’m a musician. When I go to loud concerts I wear earplugs. At a recent Korn concert I wanted to decide if I was far enough away that I wouldn’t damage my hearing or leave the venue with ringing ears. I tried the app, but I got numbers from people talking behind me, the band, clapping, so I wasn’t able to get an accurate reading. The meter jumped from 50db to 80db at a Korn concert where I was about 100 feet from the stage. While it wasn’t hitting over 100db or heaven forbid 120db, I chose to wear earplugs and I was the only one in my group to not leave with ringing ears. In summary, the app is really great for isolated spaces, but it has trouble handling multiple sounds from multiple sources and giving you a stable number to work with. I don’t recommend it for harm reduction at a concert event, but I do recommend it for checking your speaker levels, calibrating your receiver, or anything audio related that is in a quiet testing area.

Great app!!

The free version is likely the best app of its kind, and highly recommended. The only strike against it is that the premium version is subscription based, and a fairly expensive one at $4.99 per month. I suspect that for most casual users, this is far too expensive…I certainly wouldn’t pay that. I can understand subscriptions for something like a newspaper or periodical magazine, where content is changing, but not for something that provides an essentially fixed functionality. This kind of app is particularly suitable to one time purchase of premium functionality.SUGGESTION TO DEVELOPERS Create a reasonably priced onetime purchase option If you keep a subscription, reduce the cost considerably. You may be surprised how many more paid users you’d have, if you do this.

Misleading app name, free version measures dBZ only

The app name is dB, dBA Noise Meter but what the developer doesn't tell us is that the app only reads Z-weighted decibels (dBZ) and not A-weighted decibels (dBA) in the free version. All the guidelines and standards say to measure noise levels in dB(A) as A-weighted decibels correspond to human hearing. So it's really misleading to the public who don't know any better. dB(Z) levels are typically 10 decibels or more higher than dB(A) so people are always getting the wrong readings, unless they purchase the A-weighted portion. No explanation is provided, it's truly a disservice to people who think they're getting a good reading of their noise environment. Remember, a 3 dB increase in level means double the energy that reaches the ear, so 10 dB at the ear is a huge difference.Developer should make this information available to the public. They benefit from their top ranking on the app store but forget they are spreading misinformation by not explaining to the public the difference between dBZ and dBA. I will gladly pay $10 for an app that provides readout in A-weighted decibels.

Software subscriptions are nonsense

Wouldn’t it be great to be able to purchase something one time and own it? The software industry has responded to this question with a resounding collective “NO!” screamed at the top of their lungs. This app is fine. Reasonably accurate for a quick reference during a concert or in a restaurant. However, the incessant reminders of feature paywall is enough to spur me to write this complaint. This is exacerbated by the gargantuan $5 per MONTH price of “membership”. Never before in history have craftspeople required their customers to pay them in perpetuity to continue using the thing they made. This trend needs to go the way of the dodo. I would happily pay a one time fee for any product.

Amp saver

I was never impressed with my Denon 5.1 sound. I ran the auto set up multiple times with the small microphone in different viewing areas. After reading an article, I used this app, along with physical distances of each speaker to the viewer. Wow, day and night. Much better surround sound. My understanding is to bring all speakers to an equal level by adjusting the individual dbl of each speaker on the amp, using this app to measure the output. I had to lower the front to match the rear, however you can increase the volume once you are done balancing your system.

Really Nice; How About This.

This is a great tool for audio enthusiast and semi pro apps.. very useful. How about this developer... what if you had a filter for the audio enthusiast that instead of showing air plane, riveter, streets noise, etc, it showed whispering, quiet conversation, normal conversation, public speaking, quiet church music, typical church music, loud church music, Jazz, Orchestra, Country Music Concert, Rap Music, Rock Concert. Each of these have associated typical levels such as...60~67 Quiet Conversation67~70 Normal Conversation70~72 Public Speaking82~92 Quiet Church Music92~95 Typical Church Music95~102 Loud Church Music115~125 Rock ConcertEtc... you get the ideaThese are all subject to I individual styles and preferences but the ideas is to get close, some type of base line for people who really have no idea what they’re doing but they knobs anyway (and you know who you are). This is very common in church music and small clubs where speakers mics are either so soft people lose interest or so loud it’s annoying. Or when the band is so soft it ruins the mood or so loud it’s dangerous to your ears. Many churches have no idea what is appropriate sound levels or what is borderline dangerous. I think this might be very helpful.

Used to be excellent but now…

This app used to be exactly what I wanted, a simple, easy to use decibel meter with different weightings and a visualizer to see the heaviest frequencies. Paid the one time for the full ad free app and went about my time. But just recently when I used the app, it didn’t let me play music at the same time as using the app, meaning I can’t measure the music being played in my car through my phone. I was spammed with messages to upgrade to some $4.99 a month subscription for idk what and to rate the app. So I have now. The dosimeter addition seems really nice but have yet to try it. I’m sure it works great but I paid money for this app and I’m upset I’m being bombarded with messages to pay a subscription.

My mission and you might want to follow

Years ago I lost my high tones from being in the music business, competitive shooting and hunting without ear protection, whch at the time was something not known to me.My daughter and wife finally got exasperated with my asking “Huh, what did you say?”So they had me go to an audiologist who determined I did have significant hearing loss of the high tones, literally crashing off the chart. Having compensated for 19 years, it was time for hearing aids. For $6,000, great improvement shown. I’m due for new aids, another $6K.So, for the past 10 years I have spoken with some 50-60 young folks who blast music in their vehicles. I put the DecibleX app on my iPhone and demonstrate that they are ranging from the 90s to over 120 decibels. They were unaware of the damage they were causing to themselves and in some instances their children.Everyone has been nice and thankful that I’ve brought this to their attention and saved them their hearing and some $$$.Let’s pass it on!!!

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. * Privacy Policy: http://www.skypaw.com/decibelx/privacy_policy.html * EULA: http://www.skypaw.com/decibelx/terms.html
