Devices that emit spooky audio when movement is detected are a common feature in seasonal decorating. For example, a prop skeleton might emit a scream when someone walks past it, triggered by the integrated sensor. These auditory frights range from simple doorbells that play a tune to sophisticated systems involving multiple sound effects and triggered events.
The appeal of such items lies in their ability to enhance the immersive experience of the holiday. They offer a hands-free way to startle and entertain guests, increasing the overall ambiance of a haunted house or themed display. The technology employed continues to evolve, with increased sound quality, sensor sensitivity, and customization options becoming increasingly available.
