Easy to use

db 10th is a quick and easy app that gives you comparative decibel levels. In other words, its not an OSHA certified meter, but you can compare the audio volume from one shop tool to the next or one concert to the next. Even check out the increase in db from factory installed to those new pipes on your Harley. Nice!
