In the hitchhiker by Lucille fletcher what situation is this sound effect setting up?

Hello. You did not say what or how the sound effect to which this question refers, so it is impossible to provide a concrete answer to your question. However, we can consider that all the sound effects established in a radio play represent a situation, which depends on the listener's interpretation.

A sound effect only represents a situation of suspense, if you hear it interpret it that way. So, to get the answer to your question, you must hear the sound effect, or have a very detailed description about it.
