Many roosters crow at more than 130 decibels. At that level it takes less than a second to inflict lasting damage so you'd think that roosters crowing every day would slowly squawk themselves to total deafness. Since they don't, scientists from the University of Antwerp and the University of Ghent in Belgium looked into the anatomical earplugs roosters use to protecting their ears from those super loud crows.
You know how rooster crows are so annoyingly loud? Yeah, well, apparently, the birds can't fully hear their own squawking. Because evolution, of course.
