ring in one's ears
ring in one's head

His line has been ringing in my head for weeks now.

The words have probably been repeated several times, for they are ringing in her head before she begins to understand them.

The questions ringing in her head are "how to satisfy my man?"

"That is what has been ringing in my head all through dinner as I looked at those two."

The name rang in his head like a golden bell.

There had been no sound, just the words ringing in his head.

Her cold laughter still rang in his head when he thought about it.

She tried to think calmly but his words of love still rang in her head.

His words rang in her head: 'plans have to be changed'.

I cannot put into words what rang then in my head.
