EXCELLENT ! No other video explains these calculations so well. This video "EXPRESSES" rather than the other monotonous videos that only try to "IMPRESS".

How do I get the percentage difference between two dBs? I’m looking at 94 vs 97 dB and I’m trying to understand that % difference logarithmically.
