For a brand new audio gears, even cables, we clearly hear its unpleasant sound and try to
play music tru them until 300 hours has passed. But Why we dont feel this when we watch
video from brand new video gears such as scaler,DVD player or projector despite they has lots of electronic
parts as well. ? We never feel like having to play video gears all day for many days before they're watchable.
Are our brain are more sensitive to signal from ears than those from our eyes ?
