If you're thinking of adding a goat or two to your farm, you might be wondering about how much noise they'll make. Goats are actually pretty quiet animals, and most of the noises they make are fairly soft. However, there are a few exceptions.
Goats bleat to communicate with each other, and their bleats can vary in volume depending on what they're trying to say. A mother goat's bleat will usually be louder than usual because she's trying to call her kids back to her. A billy goat's mating call can also be pretty loud, but if you have a wether (a castrated male), he shouldn't make much noise at all.
Generally speaking, goats aren't particularly vocal animals and shouldn't disturb your peace and quiet too much. However, like any animal, they can sometimes make unexpected noises that can startle you (or your neighbors!).
