Mast hums can be a real problem. The C34 was notorious for this. Deck stepped masts are usually worse than keel stepped, and some models have it bad while an almost identical rig & model doesn't hum at all. Has to do with rig tension and wind direction (one theory is that mast groove is the culprit).
If you note tall, thin smokestacks the modern trend is towards spiral vanes to cause the wind to "turbulate" a bit rather than set up a harmonic. You can get some of this effect by wrapping the halyard around the mast below the lowest spreader. This doesn't help much with multiple paired spreader rigs.
It's also a question of owners.
