How to measure decibels with the NIOSH sound level meter app

For a quick lesson on how to use the NIOSH (National Institute of Occupational Safety and Health) app to measure decibels and noise, check out my latest Soundproofist  video.

So let's say the dB level in your home is 40 when it's quiet, but increases to 60 when your adjacent neighbors watch TV on their home theatre system. What does this mean w
