Ear trumpets dont amplify, but provides more surface area to gather more sound enegry. So sure, it would aid in their hunting to focus on the faintest of sounds, but if you were yelling in another room, their ear position would make an imperceivable difference in intensity, but enough of a difference for their brains to pick up the tiny difference to tune to ears to determine where you are yelling from and promptly ignore you.
You can test this yourself. Stand in front of a speaker, and shield you ears with your hands so the sound can only reach from behind them. How much does it effect the sound volume?
