Using music to improve hearing.
I listened to part of a broadcast on CBC radio yesterday about how studies (focusing specifically those at Ryerson University's SMART Lab) are being done that show music can help people hear better. It has been known for some time that musicians have better hearing later in life and studies are showing that joining a choir or learning an instrument can benefit anyone. The explanation is that following the variations in pitch and rhythm "exercise" the brain pathways that help us follow speech in noisy environments. Very interesting!
