I think the hardest part of creating a mirror for these other kinds of senses would be the fact that you need to be able to modify the 'reflected medium' in such a way that you can:

1: Determine if the subject is capable of detecting the modification 2: Determine if the subject has detected the modification 3: Have the subject acknowledge that they are the subject of the modification by attempting to correct it.

I guess hearing a crow clear his throat would be an indication of sentience.
