I use earphones for the phone and alerts function, and because they are noise cancelling, they lower the db of noise. I use Shure SE215.

Depends on how long and how noisy.
As I've gotten older, I find loud noise in general is less tolerable, so I've taken to always keeping a pair of earplugs with me. It makes being around loud music, etc., much more enjoyable.
Long term exposure to noise is widely considered to be a hazard, but walking into an average data center for an hour once a month is probably not that risky.

Depends on the type of "noise" too. Datacenters generate (more or less) white noise, which is particularly harmful long-term to the cilia in your ears because it excites all of them all of the time. A loud datacenter is much worse than a loud rock band, IMO. I personally use Bose noise-canceling headphones.
