I agree with lennox4. I think when she says 'ears closed, what I hear no one else has to know' relates to her own thoughts and what she is hearing herself say. She could be telling herself that she loves this person so much and is willing to smash into them - to be noticed - yet she doesn't want anyone else to know/find out. She is willing to make an impact on them so she can be loved just as she wants to be.
