Quizplus · Accepted Answer

The term "ambient noise" refers to sound that is present in an environment but is usually not consciously perceived. It can be described as a low-level, continuous noise that adds a sense of energy or atmosphere to the environment. This is the best description of the scenario given in the question. The other options are not as relevant - "environmental sound" is too broad and could refer to any sound in an environment, "architectural sound" implies a deliberate design or engineering aspect to the noise, and "semi-fixed noise" is not a commonly used term in this context.
