The sound is loud, but is it really loud? What is "loud"? How to judge the intensity of a sound?
Heres the solution: iNoise Meter.
How does it work?
This noise meter uses the microphone built into your iPhone to determine the intensity of the sounds it captures. Then displays it in dB SPL (Decibel Sound Pressure Level) directly on your screen.
!!! Wherever you go, you can test the loudness!!!
OPERATIONS:
Very simply, just start noise meter and see on the screen the intensity of its surroundings.
FEATURES:
- Easy to use, little interaction is needed.
- Easy to read display
REMINDER:
- The application requires that your device has a microphone.
- Decibel Meter can not be used for professional. The microphone sensitivity just allows only approximation of decibels.
