Hearing damage is cumulative. One ride without earplugs won't do noticable damage, but it definitely adds up and it's not reversible. As others have noted, blocking the wind noise with earplugs does make it easier to hear other sounds.

"I am enthusiastic over humanity's extraordinary and sometimes very timely ingenuities. If you are in a shipwreck and all the boats are gone, a piano top buoyant enough to keep you afloat that comes along makes a fortuitous life preserver. But this is not to say that the best way to design a life preserver is in the form of a piano top. I think we are clinging to a great many piano tops in accepting yesterday's fortuitous contrivings as constituting the only means for solving a given problem." - R. Buckminster Fuller
