Iconic Sounds

Door Shut- This creates a creepy and scary effect that gives a sense of isolation and darkness which envelopes the characters. Making the length of the sound very fast can create a sense that something is wrong.

Heartbeat- The fast pace of a heartbeat can cause an effect that suggests  a character is frightened. The combination of an increasing fast pace and killer moving closer towards the victim gives a sense of wrongness. The heart beat can be used instead of music as the audience gain a sense of the victims emotions.

Footsteps- This gives the effect that either the victim is running from the killer and trying to escape. Or suggests the killer is getting closer to the victim if the footsteps are slow and cautious.

Panic Sound- This gives the sense that something is going to happen and the scene is going to reach its climax, confirming something scary and dangerous is going to happen.
