Bards cant hear their own songs or voice?

To be fair if we're being realistic, then bards should not be able to really attack or do anything else if it requires an instrument, unless you think you can play a flute/ harp while running around and (accurately) fire arrows.

While we're being realistic, Bard attacks should have a relatively high miss rate and lower damage the further you are from your target, especially so if you're moving and attacking, also have a limited amount of shots, need to craft or buy arrows and can only carry a limited amount.

Could go the other "realistic" route and that the initial instrument use is to establish the pitch/get the notes right, and the rest is the Bard singing a capella as they fire arrows (which, incidentally, matches with the established lore, that Bards were born out of archers who began to sing to bolster the comrades and deal with the death of those around them in battle as they had to keep their eyes on the field no matter what and so could basically see the horror of battle more clearly).
