The other woman's voice sounded hollow and dull, as though under water.

The fear smell was gone from her, but her voice sounded under tight control.

It sounded like an order rather than a request to her; perfectly proper under the circumstances.

Voices sounded great in under the shed, deep and hollow.

When the machine said, "Good afternoon, radio audience," it sounded like an alien speaking under water.

"It sounds like the first foot in the door, the camel's nose under the tent."

She knew that she sounded like a woman under a spell.

It sounded like a tree-branch under a weight of ice.

A thin dull snap sounded in the boards under her feet.

Oh, no, it sounds unusual to me under those circumstances.
