It might be better to suppress the specific message, and let others pass.

enter image description here

code:

ClearAll[x, a]
CurrentValue[$FrontEnd, {"PrintAction"}] = {"PrintToNotebook"};
CurrentValue[$FrontEnd, {"MessageOptions","KernelMessageAction"}] = {"PrintToNotebook", "Beep"};

And now

Quiet[Integrate[(ArcTan[a*x] - ArcTan[b*x])/x, {x, 0,Infinity}], {Integrate::idiv}]
