After just reading the thread about why someone buys a K model, the thread drifted personal O2 levels and the flying high. I'm curious if anyone has tried separating their O2 levels from noise levels in the cockpit while flying long distances? I just went in a friends Bonanza V35 and compared the interior noise level with my "J". Using an Iphone app mine was 111db compared to his 103Db reading. Considering that amplification isn't linear but increases 3.16 fold per decibel increase means that it can be a substantially more fatiguing the nosier the interior is. Every-time I go on a long trip of longer than a three hours I'm beat and can't help wondering if the aircraft noise on the rest of my body fatigues me also. Anyone have any real experiences with this and their fatigue and other than ANR headsets what have you done to quiet the cockpit?
