How to remove severe background hiss in Audition CS6?

A while back I bid on an interview of one of the last living names in So Cal horse racing of the 30's, thru early 80's. Did not get the job as I was too "expensive".

Now that customer has come back to me to edit the files tha the other videographer shot. They apparently used a cheap $500 Canon and failed to use anything other than the built in mic. So we have huge amounts of hiss like I have never heard before.

I am edting in CS6. Exported the audio to Audition, tried cleaning it up going to Effects>>>Noise Reduction / Restoration>>>Noise Reduction Process. Set "Noise Reduction" at 100%. The "reduce by....db scale was at 10.

Sounds great until you turn up the volume a bit. Then you hear little "ringing" sound. Backing off to between 50% to 80% you can till hear the "rnging".
No amont of adjusting those parameters gives a satisfactory result. I think the "rnging" is in the original audio tracks and the more I use noise reduction as I described, the more apparent it becomes.

But it occurs to me that I may not be using Audition correctly. Can anyone advise me on what the best way to remove massive amounts of hiss is, while minimizing the chance of screwing up the subject's voices?
This noise occurs all thru-out the video.

Thanks so much for giving this your time-

Any chance you can post a small sample in .WAV format ?

I don't use Audition, but I'm curious to see how much I can clean up in Sony Sound Forge.
 
Try to isolate the frequency somehow?

There's no good answer, this is extremely difficult to do.

I can put you in touch with a place that has state-of-the-art noise reduction technology but they're presumably not cheap:

Try the noise reduction but you will get artifacts. Unfortunately nothing can take the place of good sound acquisition. Otherwise you're just making chicken soup outa chicken feathers.
 
Thanks o everyone for such fast responses!
Dingo, thanks for the offer to run a clip thru Sound Forge to see how it would handl it.
And Policar, thank you for the link to Flavorlab. Don' think that this client coud afford them.
Just met with the client tonight. To hscully's point, I did gently point out that there's no substitute for using decent mic's to start with. I told her that I wouldn't hold my breath on getting any better results from any possible change in processing. So she made the call to just go with what we have and call it a night. Wow what a week...glad ths one is done!
