Please understand that this answer is written with a bit of tounge in cheek, partially containing a joke. Decibel is relative measurement, there are no absolute values. So, assume we define dBA as the relative amount of apples and we define that 1 apple equals 0 dBA. Half an apple would be -6 dBA and two apples would be 6 dBA. Let us also define 0 dBB as one ...
