If you are ever curious about what volume your car stereo is at or your how loud your work environment is we’ve got a great tip for you. You can use your iPhone to measure the decibels of your daily life.
For example, you could hold the iPhone up to your head phone to measure exactly how much sound you are pumping directly into your ears. Or you could use the app to monitor the noise while you are walking on a typical street corner.
Unfortunately the iPhone is not able to measure sound levels above 100 dB, but that really isn’t much of a limitation because anything over 85 decibels for an extended period of time can cause permanent hearing loss. So if you take a reading of your car stereo and find that you typically listen to your music at 90 dB, we’d recommend that you turn your volume down. You could be damaging your ears!
Check out this video review of one of the more popular iPhone decibel meters called, Decibel.
