Summary

I ride a bicycle and wear behind the ear hearing aids. The wind noise is amplified by the hearing aids and is very harsh. This device does reduce the noise by about 70% for me. This design sits on my sunglasses arm that is 3.0 mm thick so is not likely of broad interest as is but is put out there for others to use or modify. There is an .iges file (zip) as well as the .stl file. I do print it with supports and they are minimal and don’t even have to be removed.
