Personally I think they are quite loud, but I work nights and sleep during the day when they "get lost" and start calling to each other. Also, at least my Tom's gobble all the time if I am outside, maybe its just them but it can be quite annoying on a peaceful summer evening when you are trying to enjoy the outdoors. They make noise more frequently than my guineas or chickens, but without question the guineas are more loud when they alert (it just doesn't happen very often, unless one gets lost...). Personally, and maybe its just me or my turkeys they are often not worth the cost of food or huge piles of poop. I find the chickens and guineas more interesting...
