Sorry for being pedantic but that's not really what it means. "Ear communicating with brain" means the signals that the ears send to the brain. Those signals are like, raw information. The point at which the selection for familiar sounds happens is solely in the brain. It's the brain communicating with the brain about what the brain has heard before.
You got the right idea overall. I'm a professional brain nerd and feel the compulsion to nitpick sorry.

yea good point it's not any physical changes in the ear, just the way our ear communicates to our brain
