Here's why:
* Concrete Noun: When referring to the actual sound waves themselves, noise is concrete. Think of it as the physical phenomenon that can be measured and analyzed. Examples:
* "The noise from the construction was deafening." (Refers to the actual sound waves)
* "I could hear the noise of the waves crashing on the shore." (Again, refers to the sound itself)
* Abstract Noun: When referring to a general state of confusion, disorder, or lack of clarity, noise is abstract. It's a concept or idea that can't be touched or physically measured. Examples:
* "The noise in the political arena was overwhelming." (Refers to confusion and lack of clarity)
* "There was so much noise coming from the meeting, I couldn't concentrate." (Refers to the chaotic nature of the meeting)
So, the meaning of "noise" in a sentence will determine whether it's concrete or abstract.
