Yes, ime, anytime you decrease air movement the sonics change. Also, ime, the ear adjusts to changes and hears differently at different volumes. This really noticeable when changing amps or even drastically changing settings on an amp. At first the ear is 'shocked' by the difference. Then, as the playing goes on, the ear adjusts and the new amp/new settings are not as 'shocking'. I wonder what the db levels are at a symphony concert during a particularly bombastic passage of say..... And then I found this.... https://www.theguardian.com/uk/2003/aug/23/arts.artsnews I need a db meter. I wonder just how loud things are when I am happy with an amp's sound??
