such as rock concerts, that might cause temporary hearing loss.
Temporary hearing loss might cause unsafe volumes to sound
normal.

experience ringing in your ears, hear muffled speech, or
experience any temporary hearing difficulty after listening to your
portable audio device, discontinue use and consult your doctor.
