Hoises is a term used to describe sounds commonly heard in the household (ie. "house noises"). Some examples might include the drip of a leaky faucet, a creaking door, the pinging of a radiatior, or even the eternal moan of whatever restless spirit that may happen to reside there. Older houses or buildings are usually more susceptible to hoises, but this isn't always the case.
The old mansion on Butternut Hill is full of strange and unnerving hoises; we didn't want to stay there any longer.
