That hum is tinnitus, a condition Chris Martin, will.i.am, and scores of other musicians have spoken out about. Consider this as a PSA for future you.

If you've ever been to a concert, you may have experienced a muffled ringing after you leave.

It's actually a temporary bout of tinnitus, or when you perceive sound that has no external source. Tinnitus can occur after sustained loudness.

But how loud is too loud? The standard tipping point is 85 decibels (dB), and prolonged exposure to noise at that level can lead to hearing loss, as outlined in the Occupational Safety and Health Act of 1970.

The average rock show emits about 100 to 120 dB.
