Just before the music stopped I heard a single distinct sound.

He considered the problem of measuring the time taken by a voice in making a single sound.

Then the noise again; not a single sound this time, but a whole series of them.

Never once did any of those she hit utter a single sound.

This was not a procedure they wanted to put at risk by making so much as a single sound.

It was the single most distinct sound I had ever heard in my life.

And not to make a single sound until she said they could.

The little house could not keep a single sound to itself.

It must be terrifying to see that play out without a single sound.

There was not a single sound from any of them.
