Thank you. Thank you. Thank you for shutting up and not repeating every damn call out. We can see, hear and read what's going on. Space-X launches are beautiful. Thank you!
Max Q simply means that it is at its quietest point in the flight. The onboard water suppression system is damping the sound made from supersonic flight.
No, "Max Q" is not the quietest part of a rocket launch; it's actually the point of maximum aerodynamic pressure and stress on the rocket, meaning it's the loudest and most physically demanding part of the initial ascent, as the rocket experiences the highest amount of air resistance at that specific point in the flight.
