Working with ferrets – whose auditory system is a lot like ours – a team of researchers at the University of Maryland have shown how a form of noise reduction happens in the brain. Speech and other dynamic signals get boosted while noise gets dampened, leading to better clarity for relevant signals.

How the Brain Locates Audio Targets
A recent study from Duke University has shown how our brains process the location of visual and audio stimuli differently. The write-up of the paper at Futurity.org describes the previous model as a kind of ‘zone defense’, where different neurons in the brain are responsible for a different location in space. Which neurons are firing
