If I remember correctly db is not linear, it is exponential.
3db is noticible difference.
We previously used two Honda 2000, singularly for satellite TV and others and as a pair when when running AC and microwave. We had an external fuel tank that would feed both. The fuel usage was awesome. The noise with one wasn't so bad but two wasn't exactly that great. Carbs weren't cheap.....
