Dumbledore's a crack apparator

Dumbledore's Study at the Harry Potter Studio Tour

When Dumbledore apparates to Privet Drive in the first chapter of The Philosopher's Stone, he does so "so suddenly and silently you'd have thought he'd just popped out of the ground".

When Mundungus Fletcher apparates away from Privet Drive at the beginning of The Order of the Phoenix (leaving Harry unprotected in the face of the Dementors), his disapparition is marked by a "loud, echoing crack [that] broke the sleepy silence like a gunshot". Later, J.K. writes that "Harry was sure the cracking noise had been made by someone Apparating or Disapparating."

In fact, the loud noise becomes closely associated with the act of Apparition throughout the remainder of the books.

So how can Dumbledore do it silently?

I would guess that, as the long-time Hogwarts Headmaster is a wizard of exceptional skill and talent, he likely solved the problem on his own to allow himself to appear and disappear silently. This would be a definite advantage to him when dealing with an enemy.
