Hi, funny someone else posting on this topic as I have been scouring the 'net for info on decibels. Man, it's another complete world to delve into. My reason for enquiring is that on my Pioneer receiver the optimum level for listening seems to around 40db. I thinks it's 40 anyway, although it could be -40, as the display looks as though it has a field for 3 digits??? But checking the internet, 40db seems to be just above a whipser!?!?!?!? When I turn the volume up, the decibel reading gets lower and when I turn the volume down, the decibel reading gets higher. Any and all help would be gratefully appreciated. I have read about the reference level at 0db etc, but am still unsure. Thanx in advance. Regards, Patrick.
