Here's why:
* Common nouns refer to general, everyday things or concepts. They are not specific to a particular person, place, or thing.
* "Noise" is a general term for any sound that is unwanted, unpleasant, or distracting. It doesn't refer to a specific sound.
Examples:
* "The noise from the construction site was unbearable." (General, not a specific sound)
* "I can't hear the music over all the noise." (General, not a specific sound)
