40 decibels is typical in a quiet roomFirst,
Why are you using an android phone? IDIOT! It took me ten minutes to find out my iPhone doesn't have access to your link. And second, what does your meter read when you're just sitting at your desk drinking coffee with no sound but the refrigerator in the background. The meter I installed is detecting 40db at that level. Is my app junk?
