vitruvian is correct about Extended. By PM to Kromm:

Obscure affects an area to begin with, while Invisibility affects a broader set of senses to begin with, but that's a tradeoff. And note that many of the examples in Powers are non-visual: magnetic detection, scanners, etc.

I think that means you can also simply say Inaudible: Invisibility to Hearing [40], which would cover all forms/ranges of hearing*, but wouldn't affect vision at all.
