Lol, I agree. As Im sure you are aware, hearing protection should be worn with most equip such as tractors without a cab, so I really like these https://www.earplugstore.com/howard-leight-percap-banded-earplugs.htmlMy main complaint about hst is how loud the whine is.
They are relatively cheap, comfortable long term, and I wear the band positioned under my chin because I like to wear a cap. Just thought Id suggest them, if you are so inclined. And yes that whine noise is loud
