Using a Reverb Zone to create a zone of silence

Hi,

I have a level and there's a certain area in which I'd like to create a zone of silence - i.e have all 3D sound effects completely muted within that specific area. Is this possible to do with a reverb zone or something similar? Or is there a better solution? Please bear in mind I'm not a coder so it'd be great if there was some way to do it without much coding/scripting.

Thanks in advance for any help.
