This is your brain on noise

General Asylum

General audio topics that don't fit into specific categories.

Or at least a mouse's brain. Interesting study on how prolonged exposure to high SPLs physically alters the auditory nerves. Synaptic nerve endings are enlarged, while production of neurotransmitters is reduced, possibly allowing the mouse to block out the irrelevant noise and focus on more meaningful, lower SPL sounds occurring at the same time. The alteration is non-permanent: reduce noise exposure for awhile, and the cells go back to normal. Thanks to Mike S on the PE forum for the link.

Depends on the levels and the exposure time. (NT) - Kal Rubinson 05:16:32 06/11/15 (1)
