Characteristics of Drumheads
A drum head being tuned (MusicRadar).
Drum heads require very unique characteristics under extremely stressful conditions. The head must be able to maintain shape and stiffness when getting struck by the drum stick. The drum head must also be able to be put in extreme tension when the head gets installed. To tune the drum head, the drummer changes the tension on the head, giving different vibrations. So the head must be able to keep its strength after multiple changes in tension. Drum heads get changed dependent on how hard the drummer hits and how often the drummer plays, but most often it's around every 4-6 months. With this long life, drum heads must also have a very high resistance to fatigue.
