The best part of the advantage from Hyperglide comes from the front chain ring shifting, and if the "chain noise" you are speaking about is coming from shifting in the front from the little ring to the big ring - then yes a "Hyperglide" chain will help IF you have "Hyperglide" (style) front chainrings. Some KMC chains are rather heavy and wide, do you have one that matches the number of speeds in the rear cog? There are different chains for 5-7 gears, 9 and 10 speed gears. 8 speeds are a little odd, some can take the some of the narrower 5-7 speed chains like an SRAM PC -890, others will rub in certain cross chain situations. "Chain noise" can come from a few things, worn chain & new gears, lack of the minimum lubrication, and also a really bad chainline. Some noise comes from indexed shifting not matching your new Hyperglide rear cassette. So, what kind of noise do you have?
Basically, you are going to have to experiment a bit and look at a lot of factors unique to your bike to sort it all out. Often adding one nice drivetrain part to an older bike quickly leads to buying several more to make it all work right. but at the least you are going to have to guess at some changes and adjustments to see if it works. My advice is to buy all new chain and chainrings that match the Hyperglide you just bought, now, while the cogs are still new because it is hard enough to Frankenstein the driveline on an old bike, starting off with fresh stuff eliminates some key complications right away Your shifting is 7-speed, right? Indexed 7-speed? Or downtube friction levers ( without detents for 5 or 6 speed ) that might just need tightening down to keep from slipping partway into a higher gear as you pedal - which makes a lot of noise.
