Hearing Protection
Hearing damage does not reverse; manage level and duration together and rest before the ringing starts.

The problem
Hearing loss is the most overlooked occupational injury among engineers and players because it arrives slowly. By the time high frequencies blur and tinnitus will not fade, nothing can be restored. Protecting hearing is not about working less but about treating level and duration as two variables that must be managed together.
How it works
Hair cells in the ear do not regenerate. Damage depends on sound pressure level multiplied by exposure time: every extra three decibels roughly halves the safe duration. Short exposures cause a temporary threshold shift that feels dull and recovers with rest, but repeated shifts become permanent. Low frequencies do not feel loud yet carry great energy and damage just as well. Headphones deliver sound straight into the ear canal and raise the risk.
Settings and practice
Set monitoring at a level you could work at for hours, and raise it only briefly when judging detail. Rest for a few minutes every forty to fifty minutes. Use flat-response earplugs for rehearsals and shows rather than cheap plugs that only cut highs. Measure your own habits with a sound level meter once. Stop and rest at the first sign of ringing or dullness instead of pushing through.
What to listen for
In a long soul rehearsal, note when fatigue arrives; in quiet chamber passages, whether you are creeping the volume up; in organ low end, whether the headphones get louder as you listen. The first sign of fatigue is usually missing high end, not a feeling that things are too loud.
