I had this sound very loudly at different speeds/rpm's. It is now fixed. Try this. Where your stock air filter is, the black plastic device that holds your filter has a worn out gasket on it on the bottom part of it. It may even be gone. Even if it is there, scrape it off and put weatherstripping in its place. Make sure to have a new filter also. My whistling noise was so loud it sounded like a tea kettle. Now, it is completely gone. My mechanic couldn't figure it out so he replaced the serpentine belt and idler pulley which did nothing to alleviate the problem. I read about this solution and even saw pictures of what I did with the weatherstripping on this forum under the subject about a bogging noise. It is not the alternator or the belt. It is the air intake leaking just below the air filter on the device the air filter installs in to. A 3 dollar fix from lowes. (Weatherstripping).

I just bought my 02 rwd 4.2L 5-speed just before our serious cold snap a few weeks ago. Then the temp dropped (0-20F) over nite. The following day, after a normal 20 minute local trip home from work, I pulled into my driveway, put it in neutral and that high pitched squeel krept in at idle from the belt/pulley area under the hood. All my gauges work and are showing good readings - including the alternator!
I don't know the age of the belt but it doesn't look ancient. The alternator and tensioner are still working.
After reading related posts on the subject I decided maybe some simple lubrication was in order in these freezing cold conditions (-0 to 20F).
With truck OFF, I sprayed a liberal amount of crc belt dressing to the grooved side of the belt and (Important!) using the tiny red straw provided with the can, I sprayed liberal amounts of all purpose advance auto brand lubricant just behind the top of the alternator and tension pulleys, two good doses 30 sec. apart, starting and idling the truck in between to make sure some of the lube was forced into shaft/bearing space.
Then I took a normal five mile drive to work in the lube.
It wasn't cured completely right away, but after a few days of normal local driving, I'm glad to report that the squeel has vanished under all cold weather conditions. For the time being anyway. It's been a week or so.
It may return but at least I'll know what to do next time.
