What’s good for your body is not necessarily good for your ears. Loud music is an integral part of many workout activities — spin classes are a prime example.

If you doubt that, come on over while Gracie, my granddaughter, pierces the air with a sound that is somewhere between a siren and a scream that will leave you vibrating for days.
