How quiet is your K3?

I'm asking because mine seems to be getting noisier as the days go by. The shutter seemed whisper quiet when I first got it but now about 3 weeks down the line it's noticably louder with the mirror giving a distinct thump as it moves. I'm worried that something is coming adrift so I'd like to hear from others if possible.

Mine's a month old and I think it is the same as it was new. It possibly may seem less quiet because at first it was a contrast from the clatter of the K30 but now I am getting used to it.

Thanks for that dcweather, it's occurred to me that I'm imagining it which is why I asked for others opinions.

Very quiet!

Regards
David
