I just gave a solution and you ignored it. If you're complaining about speedsters then you don't know much about the Flash, he runs at light speed and is a prominent member of the Justice League. his sonic boom would be no different than someone with wind powers and the ability to create hurricane force winds. I see problems with the Hulk in a team setting than this since he can crush almost anything in sight if he loses control and he is a part of the Avengers

The Flash essentially ignores physics, rather than trying to leverage them into powers. Once using physics, it's a good idea to make sure you understand what you're suggesting--maybe not to a degree level, but at least to a 'I checked the basic physics' one.

Once you start going on about sonic booms... well, I've checked the measurements, and at point blank it's basically something heavy slamming into your entire body, along with a literally deafening noise. This is just by going past.
