I've recently switched my main body to the D3s, and took it in for sensor cleaning. I noticed when I turned it on at home that it didn't make the high-pitched sound that I thought I recalled hearing (always heard on my D300s when cleaning).
Then I noticed the option was turned off, so I switched it back on, and I still can't hear the high-pitched sound. Am I losing my mind, or can you hear this sound when the D3s does the sensor dust-off at startup? I always always heard it with my D300s. Now that the option's turned back on for my D3s, I can't hear a thing.
My question is, am I supposed to be hearing the sound? (Did I imagine hearing it on my D3s, or did the camera repair shop break this feature when they did a sensor cleaning?)

Thanks--I've only had it for a short time, so I couldn't recall if I routinely heard it with the D3s or if I only ever heard it with my previous body and am remembering that. I really thought I heard it with the D3s. When I was noticing sensor dirt, I cycled it on/off several times to try and shake it loose, and I swear I heard the sound each time.
Stupid question (humor me). Since a friend said he also could not hear it on his D300, which was an obvious sound to me, I wonder if he just can't hear the frequency. Have you heard it on any camera body?

Either that, or the constant ringing in my ears masks it.

It's a high-pitched buzzing sound, almost like a faint ring. Friend cannot hear it on any of his cameras, so now I don't trust him when he says it's silent on the D3s.
It's a possibility that the ultra sonic oscillator that operates the self cleaning mechanism in your D300 was out of calibration and had drifted down into the upper audible area. The same thing can happen with the oscillator in AFS lens motors, especially if the lens was bumped. The fact that you could hear it on your D300 doesn't mean your friend's D300 has the same condition. I have 5 bodies with self cleaning and the only body I could hear anything was with the d300 pressed against my ear. And in that case it was not a buzzing sound but more like a bubbly sound but extremely weak. It doesn't mean anything if you can't hear it on any other camera body. You're not supposed to unless you have Superman hearing.
OK, thanks, all. Yeah, my D300 made that sound from day one. Not something you could hear in a room that wasn't quiet, but if it was right by your head, was an obvious high-pitched buzz. Oddly, that one never had a dirty sensor.
Testea brand-new D600 in the store today, no noise. So maybe it was peculiar to my D300, but I'd swear I heard it on my D3s before servicing (and them turning it off).
