Brainstem Comparison in Plain Language

The comparison happens early — brainstem nuclei that already exist to locate sound in space. That is the honest, non-lab sentence.
Your ears send timing and intensity clues so you can tell a bus on the left from a voice on the right. Feed those same circuits two close pure tones and they can produce a beat.
Naming superior olive and inferior colliculus is optional. What matters is this: the beat is not a speaker trick and not a cortical spell. It is an old localization machine asked a slightly odd question.
Science on this site stays at that altitude unless you open a paper essay. Then the PDF is the authority. The Console is the instrument.
Brainstem Comparison in Plain Language is a door, not a clinic. Non-lab explanation. Sit with a true-stereo pair if the hour still wants one. Skip it if silence is the better instrument tonight.
