I would try and track down the source of the noise and eliminate that as much as possible first. Putting sound absorbing material around the cockpit will help isolate the cabin from mechanical and exhaust noise would be a good starting point. Under the carpets, engine side walls, rear deck and side panels and doors.........as the cars has little insulation material and if you select the right material you can also isolate/reduce engine heat sink into the cabin in summer. Then I would address all the areas where the hood /door seals are less than perfect and allow draughts and wind/traffic noise to enter the cabin, may need some neoprene or various size D section rubber seals to reduce that source of noise.
Unfortunately there's not a lot you can do to stop the wind noise when the hood is down at speed. I would try and isolate as much as possible extraneous noise where possible, as shouting or gesticulating is no fun on long journey and not good for your long term hearing.Good motorcycle intercoms do have background noise cancelling features and speed/noise related automated volume control.
Whilst it's,not explicitly illegal to wear headphones or ear defenders while driving in the UK, but it's highly inadvisable and maybe dangerous, as it can lead to charges of careless driving if you miss road sounds like horns or sirens, resulting in fines (around £100+), penalty points, or even a ban if an accident occurs, because you must concentrate and avoid distractions according to Highway Code Rule 148
