ELI5: Why are some people's sneezes really violent while others are barely audible.

I am referring to the natural way people sneeze, regardless of social conditioning. I for example, sneeze very violently and loudly no matter how much I try to control it. Other people I know are able to sneeze soft and quietly. What is it that accounts for these differences?

There's certainly a combination of variables. 

Social circumstances can affect how obnoxious we are willing to be with our sneezing, or coughing. Either trying to be obnoxious or trying to be stealthier and more controlled.

Then there's the threshold or subjective sensations your body feels when it wants to sneeze. We all feel subjective amounts of tickling on our bodies, the same is true of what our nose can take before it has to release itself. Stuffy nose, runny nose, foreign particles caught in nose hairs, etc. All affect what has to be discharged and how aggressively. 

I have read that muting sneezes is bad for you because it's very easy to rupture blood vessels, especially in your eyes. Definitely not a good idea.
