Decibel meter

Unsure how accurate it is but it’s lots of fun

Joan from Denver

Moved to the city with a beautiful view but with industrial air conditioners across the street. I use the decibel meter to see when it goes beyond the acceptable level. I contact our city representatives and they respond quickly because I give them an exact decibel reading. Great app!
