That Loud Fitness Class Could Be Making You Deaf, Study Shows

In today’s trendy, nightclub-like fitness classes, the blaring music meant to push gym-goers through one more rep could also be putting their hearing at risk.

The sound levels in group exercise classes can reach as high as 108 dBA, a decibel scale adjusted for human hearing. That’s as loud as a rock concert, according to some research. The thinking goes, the louder the music, the harder people will exercise.
