Human ears don’t interpret and perceive sound the brain does.For sure you are right .... But
When i walk it is ME who walk, not my legs or only my brain...
In the same way I interpret the sound to be music for me because my ears and brain act as one...
In a word "distinguishing" does not mean "separating"....
« If i understand your ears can think and your brain listen ?»-Groucho Marx 🤓
« If there is millions of neurons in the guts we can think of the guts to have a brain of their own, it is the same for any organs even the ears, then we can say that the brain is all over the body, and we can say that the body is INTO the brain»-Anonymus Smith
