Audio illusions

Poppy Crum, Chief Scientist of Dolby Labs has posted a commentary on the Yanny vs Laurel phenomenon recently on LinkedIn at

Now a new example of the brain's ability to shape how we perceive audio has surfaced.

I guess this is a demonstration of why perceptual audio coding seems to work so well for so many people.

We now have a gold dress/blue dress moment for audio!

Having listened to teh sound grab, - is E-yelley an option?

I tried shifting my auditory attentiveness over an extended period of time whilst listening to this piece repeating. I started to  get “turn the bloody thing off". Astounding!

Hi all

I heard an excellent demonstration of this illusion on the Drum last Friday (I think). The first time they played the full sound I heard one “word”, but when they filtered it to emphasise the high and low filtered parts I could hear each one as clearly as these confected “word-like” sounds could be distinguished. This illusion is an excellent example of psychoacoustics at work, and it is an example of how compression can work with the brain replacing the missing sounds with a construct of its own.
