That all depends on the method of encoding being used on the
input/source side.  If you are using a VBR (variable bitrate) method,
such as the default/recommended encoding method for Ogg Vorbis, the
bitrate will be much less during these silent parts.

Alternatively, if you're using a CBR (constant bitrate), the bandwidth
will be nearly constant regardless of level of sound input, even during
silent segments.

Neither of these modes have anything to do with Icecast itself, but
rather, everything to do with your stream source.
