Final answer:
The situation described is an example of semantic noise. This takes place when there are differences in understanding or interpreting words, phrases, or symbols in communication.
Step-by-step explanation:
In communication, the scenario you described where everyone has a different interpretation of the project completion deadline because the project manager said she wanted it completed 'soon' is an example of semantic noise.
Semantic noise happens when people have different interpretations or understandings of the words, phrases, or symbols being used in communication. This kind of noise leads to misunderstanding and confusion. The term 'soon' is subjective and can mean different things to different people, hence causing semantic noise in this instance.
