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 Conversation
67~70 Normal Conversation
70~72 Public Speaking
82~92 Quiet Church Music
92~95 Typical Church Music
95~102 Loud Church Music
115~125 Rock Concert
Etc... you get the idea

These 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.

Very Good, With One Quibble...

I’ve used a couple sound meter apps over the last few years along with a commercial quality sound level meter. I would put this up there with the best of what I’ve used. This review is for the purchased, “pro” version of the software. That I can pay $4.99 and use the processing capabilities of my iPhone in leu of spending $150+ on a professional, stand-alone meter blows my mind.

The level of detail shown in the various portions of the screen offer a broad range of information to the user. You get both numerical and graph output as well as dial analog output of minimum and maximum readings, duration, etc.

One quibble is that when I pause the meter and reset it, it asks if I really want to, which is okay, but immediately restarts the sound reading, even if I don’t want it to. Also, I’d like for a reset to take the meter back to “0”. It restarts at the prior average. I would like to see these twin issues corrected, and I’d then give the app 5 stars.

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.
