In the operation I work for (UK-based EMS) both sets of crew [pilots and paramedics] wear Alpha bone-domes.
This doesn't upset the pax because a) They are too sick to care or b) This will be the one flight they have in a helo in their life and won't think about it.
Our casualties and pax wear headsets for the above reasons this is also why they are not issued with Nomex flying suits and goatskin gloves.
Think about the repercussions if we did otherwise.
