They suggest that when you hear something, it may not sound the same to me.
…Scientists at the University of Oxford are trying to understand how the ears and the brain work together. They fit ferrets with auditory implants, trained them to respond to sound, and then looked at the way their neurons reacted. It turns out that each ferret’s neurons in the auditory cortex responded to changes in gradual differences in sound but each ferret responded differently.
The researchers say this is applicable to humans. They say this means that our brains are wired to process sounds depending on how our ears deliver that sound. So if you suddenly heard the world through my ears, it might sound quite different.
This explains a lot…
