My chain wasn't making much noise at all when I was running a 1/8th cog, 3/32 Chainring, and 1/8 chain. But when I replaced the Chainring/Cog/chain and made it all 3/32, it is virtually silent.
Also the new chainring appears to be somewhat directional in a way. It wants to go on the spider in a certain way, and depending on which way you put it on, it 'faces' one way or another. This actually I think may have improved my chainline (though it was pretty straight before), and now It appears to be as quiet as can be.
