Camtasia provide a feature to silence part of an audio track
Is there an easy way to add a low level noise fill instead?

have you tried reducing gain to something like 5%, instead of silence?

no the idea is to replace audio, not lower its volume.
Noise fill is a standard technique to avoid the dead silence
that would result otherwise.

OK, thought you were looking to silence spaces in audio

perhaps record a audio clip that meets your needs for background, keep in Library. and use it wherever?

just brainstorming

Look in the Windows store for a "White Noise" app. There are several to choose from.  Then do as kayakman suggested, record the noise, adjust the level to liking then save.

Ammicht, 

Are you wanting white noise, as suggested elsewhere, or are you wanting "room tone"? 

I define room tone as the quietest part of your recording without it being actual silence (i.e., a split in the audio where there's nothing)? 

I know audiobook narrators will let the mic run, step out of the room and come back after 30 seconds to 2 minutes to find the very quietest part of the recording. They then use a selection of that room tone to fill cuts in their audio so it sounds like there's silence without it being a complete drop. 

How noticeable, or present, room tone has a lot to do with the microphone you're using and how quiet/treated your space is.

I go to my audio track and copy a section of "noise", then split the track where I want and paste the noise clip.  Trim as needed.  It works nicely for me!
