Where: Psychology Conference Room 128

When: Friday, January 17th, 1:30pm

Remarks on hearing loss from music and noise exposure, SNR loss, SNR-loss tests, sniper-localization loss, and diplacusis.

Abstract: Review of theories about causes and effects of various hearing losses, including dead patches on the cochlea causing false pitch (Yehudi Menuhin could no longer play the violin because of his diplacusis).  A Magic Formula for predicting localization ability and intelligibility in noise under virtually any condition, given the results of a couple QuickSIN tests, and Brain Rewiring — Slow (10,000 hours for a professional musician) and Fast (reconnecting with once-learned tasks “I once could play Back Home in Indiana”) — will be discussed with regard to SNR-loss retraining.
