I was using Wipperman 108 track(?) chain 6-7 months. It's kinda loud on my bike too. I use wet lube and then it is a bit quieter. It could be because your chain and/or gears may have worn out. ... But then "108" was pretty loud when it was new too. Recently I replaced it with a low-end bushless track chain for giggles, and it runs so quiet it feels like the chain broke loose. ... I might go back to "108" if this chain doesn't work out, I would rather be loud than to feel insecure.
