Keep Your Eye on Sound Levels With Decibel Meter Pro
Sound is wonderful, especially your favorite music. However, it can also be harmful. Keeping tabs on what the ambient noise level is can be crucial to preserving your hearing, but that used to require expensive meters. Our iPhones, however, have everything needed to measure those potentially dangerous sound levels. They just need the right app to interpret the information coming into the microphone. Decibel Meter Pro is just that app.
Decibel Meter Pro is easy enough to use for simple tasks, but it's also feature-rich enough to take the place of expensive decibel meters. You can maintain a running measurement, watching sound levels fluctuate. The app keeps up with changes in volume, letting you know when a particular threshold is exceeded.
That's where you have to watch out. The human ear can only handle noise levels up to around 85 decibels, so you should avoid listening to sounds louder than that without hearing protection. Decibel Meter Pro can tell you when it's time to put on your hearing protection, since you can easily see the decibel level.
You can also record decibel readings over time, with geotagging to mark where that noise level was marked. This could be important in establishing where noise ordinances should be established or better enforced, or recording how loud your favorite rock concert really got.
The best way to meter sound levels
What's truly unique about Decibel Meter Pro is the spectrum analyzer. If you turn your iPhone into landscape mode, the spectrum analyzer expands to fill the screen and you get more options. You can change the graph, adjust how it records various sound levels, and get much more information about the sound levels.
This is a free app, but it does have certain limitations. Some users in the past have complained about the pop-up ad to purchase the unlimited version came up too often, but I only saw the message once every 15 to 20 minutes. That's pretty reasonable for an app as fully-featured as this one is.
If you want a good way to measure sound levels without breaking the bank, look no further. Decibel Meter Pro provides you with all of the information you need for casual use at a price you can't beat. It's free. If you need more comprehensive tools, the in-app purchase for the premium version won't put much of a hole in your wallet.
