Can I reliably use it to judge whether or not I need to wear ear plugs? I was at an outdoor festival for 45 minutes to eat with my family and the decibel meter on my phone fluctuated from 80 to 90 decibels so I didn't wear any plugs.
Does anyone know if that meter is completely useless or does it actually do a good job of telling you how dangerous the sound levels are?
