The term 'haunted house noise' can refer to two distinct sounds: a MOAN and a CREAK. A MOAN is a low, mournful sound that is often associated with sadness or despair. It is usually made by humans, but can also be made by animals. A CREAK is a sharp, high-pitched sound that is often associated with an object being opened or closed. It is usually made by a door or window, but can also be made by furniture or other objects. Both of these noises are commonly heard in haunted houses, giving them an eerie atmosphere.
