Deer hear well, but it’s the type of noise rather than the amount that will set them booking for higher ground and bigger berries.
The noisiest critters in the woods are squirrels and turkeys. If deer ran at every noise they would never be still. Work on “human” sounds….symetrical cadence when walking is a dead giveaway. A noisy arrow in flight is probably no more alarming than a Blue Jay whooshing past their heads.
And remember what Patrick F. McManus said about his dog “Strange”; (paraphrasing) “that dog wouldn’t notice an army of Cossacks bivouacked in the back yard, but could hear a shotgun shell being dropped into a flannel shirt pocket at fifty paces.”
