The opposite might also be true. In order to enjoy the loud parts of a park, many people also need a quiet respite. As someone who has been active in Disney forums for a long time, the topic comes up all the time. I would almost go so far as to say most families enjoy theme parks more when the parks have a few quiet areas with lots of trees.
Indeed, one problem that Islands of Adventure has is the loud noise from Hulk, it is even quite audible at Royal Pacific. I notice it right away when I get to the hotel. It looks nice, but hearing Hulk somewhat wrecks the atmosphere. Noise pollution. The hotel would be much nicer, IMO, without the loud noise from Hulk.
Remove the quiet, and you might lose a significant number of parkgoers.
