Hulk took a whisper from BB twice without getting shredded to pieces(He got knocked unconscious during one of the instances but his body didn't get ripped to pieces on both of those occasions), which shows that his body is capable of acting like a shock wave absorber proving Creshosks point.(BB's voice varies from a sound wave to an electron ripping phenomena depending on the writer but in both of these particular instances his voice was portrayed as a mechanical wave)
Making that whole hypothetical situation where the Hulk should kill people via the flexing of his muscles moot.
