Agree or not, that an empty mind makes the most noise

[Starmix]

People who lack a deep understanding or meaningful engagement may seek attention through excessive talking or disruptive behavior. A quiet, contemplative mind, though seemingly empty, might be actively processing thoughts and ideas internally. This interpretation depends on whether “noise” is literal or metaphorical and what “empty” implies about a person’s state of mind. We can't also blame this kind of person, he might have insufficient knowledge of his action as right or wrong.

You are right, people who often have notting to offer are the ones who tend to make more noise overtime.

Those kinds also love complaining and arguing for no reason. It seems they lack attention. They are also annoying.
