I’m leaning towards transport as well, but I wonder if music at events could add up to a lot too.

Large crowds can be noisy, but I feel like they’re not as consistent as transport noise.

I'm not so sure about that. I remember a practice question that mentioned military activity could be significant too.

I think transport is a major source of noise pollution, especially with all the cars and planes.
