   Science Daily article about wind noise and helmets.

 


What surprised me is the claim that bone conduction of noise can damage
hearing.  I wear earplugs myself, and they make quite a difference.  Without
earplugs, if I go on the freeway for a while, when I get back, there is
temporary threshold shift:

But if I wear earplugs, there seem to be no effects.

All interesting and relevant ...

It gets way too loud without earplugs though.  I grew up on a farm.  No
tractor cabs in those days.  There was plenty of exhaust noise.

If the measurements show that there's a problem, there's a problem.
