All camcorders will make some noise... it's hard to tell from your description if yours is noiser than it should be, or if your ears are particularly good at picking up the noise.
Here is a link to a sound test on the HC46 (identical to the HC44, only difference is HC46 has DV-in).

If you translate the French it says something like very faint noise when zooming at high speed, and there is some tape noise in very quiet settings but not noticable in most situations.
This is not a model known for it's noise.
