We measured the volume in BB King on the Nieuw Statendam. It was consistently over 100 dbB, which is dangerous. It's too bad, but for us, the music is too loud, even without my hearing aid. It's so loud, actually, that I can't hear the detail of the music. You are absolutely right that what seems loud to some is just right for others, but in my opinion, the volume should never be so loud that it drives people out of the room. We love music - in fact, one of us has made his living making and teaching music since he was in his teens - and we feel cheated that we can't enjoy that part of the trip. The musicians are universally top notch on HAL, something you really notice when you go on another line, but sometimes I want to send the sound techs off the nearest gangplank.
