Supposedly our voices are too low and we sound like noise to them. I watched a video where scientists transformed their voices to the same frequency as a mouse and they were able to train a cat.
Every cat owner can tell you that they do know their names when spoken. Also, people can train cats without transforming their voices.
I own cats, and I'm not sure if they are reacting to me or my voice. Regardless, I never said either was impossible. Only they react differently to high pitches.
I mean, you did say "we sound like noise to them", which implies they can't pick out their names.
My cat knows my dogs name.
I dont think the ear position aids in hearing amplification. It aids in spatial audio positioning.
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?
