back when I started shooting longbows, no one put silencers on them, and everyone knew they were way quieter than recurves or compounds. Everyone shot them and got used to the feel of the string hum and quietness of the low vibration. Nowadays, someone will shoot a bow three times and start tinkering with silencers and all sorts of stuff.
I would be willing to bet, that if someone takes the silencers off their straight end longbow and tunes the bow to a lower braceheight around 6" or less, and goes out for one month and shoots at least 100 -200 arrows, they won't even miss the silencers, will be amazed at how quiet the bow is, and the string hum will be ignored....and probably won't put the silencers back on because they now know how good the bow can really shoot.
