What I'm talking about is the ability of human listeners to 
discriminate between (that is, mentally separate them from each 
other) audio frequency signals that are close in frequency. 

The science of psychoacoustics is extremely well developed, and the 
principles I'm stating have long been well understood by those who 
have studied them. Yes, there are differences from one person to 
another, experience matters, and humans can learn lots of special 
skills. But most of us are starting from the fundamental place I've 
described.
