Final answer:
The term 'configuration' in this context refers to 'Spatial extent'. Loudness relates to intensity, measured in decibels, while the perception of frequency is pitch. Loudness changes with variations in sound wave amplitude, but pitch remains unaffected by loudness.
Step-by-step explanation:
Configuration in the context of the student's question refers to 'c) Spatial extent'. Loudness is a term used to describe the perception of sound intensity and does not directly correlate with the configuration of a spatial arrangement. When discussing loudness, the related concepts include sound wave properties such as amplitude and frequency. The word or phrase used to describe the loudness of sound is 'b. intensity level or decibel'. The occurrence of a sonic boom depends on the 'a. speed of the source'. Additionally, the perception of frequency is known as pitch, whereas the perception of intensity is called loudness, measured in phons. When you speak more loudly, the 'a. amplitude of the wave' increases, but not the pitch because pitch does not depend on intensity.
