How to get rid of tinny sounds in Audition even after Noise Reduction.

Hello,

This has been bothering me for quite some time. I did the capture noise print and then noise reduction (process), and my audio still sounds tinny. What else can I do to fix this? I've tried Parametric Equalizer, and it still sounds tinny. I will give you a small sample of one that has already had the Noise Reduction done on it. But it still sounds tinny. What do I do now?

I am not a technical person, so if someone can give me the best way and the db that I have to put it under, that will be greatly appreciated.
