There's a lot more noise from leafblowers and construction that penetrates my noise cancelling headphones at home, than I have ever experienced in an office. There is more in-office noise, yes, but that seems to be better managed by aforementioned headphones.
(FYI: A noise-cancelling headphone works best for hums and other "repeating" noise; construction noise is much less predictable for the headphone to get ahead)
