A tool that lets you hear both Yanny and Laurel
I think what's going on here is that the context of the sonic character of an individual's voice is crucial to the  brain's processing of the phonetic content of utterances.I spend my whole life listening critically to things.  I was 100% YANNY on two sets of headphones and signal amplification paths.  When I moved the slider bar about 1.5 notches to the left, LAUREL sort of "came into focus", and I felt like I grasped the human voice behind this severely distorted recording.  Then, when I moved the slider back to the neutral position, I could not hear YANNY at all anymore.  Only by taking a brief pause could I 'reset' my brain to hearing YANNY.There's another processing step going on that helps us deal with distorted or band-limited voices.  We're reconstructing  in our heads the ideal sonic image of the human voice we're supposed to be hearing.I hypothesize that if the sample in question came at the end of a few words by the speaker, not related semantically, e.g. "right, seven, purple, elephant, laurel", so the listener could reconstruct a more complete "imprint" of the speaker's voice in their mind, the YANNY outcome would drop to <1%.
