Researchers Identify Brain Regions in Blind Individuals Responsible for Sharpened Auditory Function
Research has shown that people who are born blind or become blind early in life often have a more nuanced sense of hearing, especially when it comes to musical abilities and tracking moving objects in space (imagine crossing a busy road using sound alone). For decades scientists have wondered what changes in the brain might underlie these enhanced auditory abilities.
Back to Basics: Hearing: Is It 7 dB, 3 dB or 0 dB?
Marshall Chasin, AuD, discusses the Minimal Audible Field (MAF), or the softest sound that normal-hearing people can hear in the normal diffuse sound field at 1000 Hz, and explains why sometimes less is more.

Scientists Uncover New Clues to How Pitch Perception Evolved
Pitch perception is not a skill unique to humans, say scientists from Johns Hopkins University (JHU), where a recent research study reveals that marmosets, considered to be “ancient” monkeys, appear to use auditory cues to distinguish between low and high notes associated with melody.
