Yeah I had a question like that almost verbatim on an exam from a Perception class I took last year. You can't localize sound based on timing or intensity differences between your ears in the mid-saggital plane; your pinnae are what help you determine where a sound is based on whether it's above you or below you by changing the frequency distribution (or something) of the sound.akalin24 said:I thought they were asking in what direction the sound would be indistinguisible to both ears. In other words you couldn't tell what direction it was coming from. Running vertically down between your eyes runs alone the mid-saggital plane. That's where you have symmetry on both sides..
Seemed like a good choice at the time?
