They don't react to your sent, they react to sound. Or at least more to sound.I have walked right next to a Falmer, if he used smell to detect I must have been down wind of him because he did nothing.

I would assume all their senses have been altered, they cant rely on sight, so they use what they have, and seeing at they have great aim for blind creatures, I would say they have done OK in adapting.
