SoundLevel: Decibel Reading

Sound Level is a simple but powerful tool for getting a quick sound reading of the current environment. The readings have been calibrated to dBA, which is a weighting that matches the human ear, and Sound Level provides comparison values so you know what the sound is equal to.
All results are graphed so you can go back in time and take a look. If you have the pro features (a one time in-app purchase), you even have the ability to export your results as a CSV file!
Key features:
* Quick sound level measurements
* Beautiful, intuitive UI
* Peak and max volume count
* Baseline sound comparisons
Sound Level is that must have app for quick and painless sound measurements.
