I was wondering what if a vibranium shield protected someone from Black Bolt' sonic scream... Can it completely vibration absorbed

as Howard Stark said? Or most of the energy will be converted into another form,and the one who behind the shield will be deafness and internal bleeding I guess. What I can't understand is that Steve Rogers was hold his shield hit by a grenade and flew in the air(CA-WS), if the shield wasn't made by vibranium then makes sense he will fly.

I also wondering that Black Bolt Roaring screaming as loud as he can to Thanos what will be? I know he can't hurt the mad Titan in comic, I think it will at least destroy his armor , might make him bleed.Unless Thanos's body is stronger than Vibranium. Since his armor can't protect him (Unable to withstand Stormbreaker)why does he need it？
