tom swift among the diamond makers

 so a rooster crowing is pretty loud 140 decibels of sound which is super loud. like a gunshot or a military jet taking off so how does this creature stay not deaf. beacoase remember his ears are right next to his mouth first the rooster can have these hair things all over his ears which help muffle. it but still his wont stop all the sound another thing is that when it tips its head back it actually has these 2 bones or flaps or something go over the roosters ears completely muffling everything almost you could prably still hear some but not as much as normal.
