This doesn’t apply if you got a motorbike helmet

I found these bits of faux fur-like material you can put on the straps of a bike helmet which help reduce wind noise.
Combine it with dynamic ear plugs / ear buds, and it seems to reduce the grating fluttering of wind noise by shout 40-80%. Depending on configuration.

Been getting more used to the ear plugs as they let me echolocate, which is a godsend when dealing with the crazy car drivers.

Note: this isn’t a golden solution. It’s just what I found that helps with commuting in a car centric hellscape while having insanely sensitive hearing.
