A noise started and a cold wind blew out of the wall into the room.

Maybe the computer made noises and things started happening on it?

The real noise would start when the kids came in at six.

He went back in, but the noise started once more.

Slowly, he got to his feet and, immediately, the noise started again.

The noise of their little feet started coming down the wall.

He was glad to see they hadn't been upset enough to try to run off when all the noise started.

I was fishing under the counter when the noises started.

But no footsteps came toward them, and the noise around the pool soon started again.

I was getting out my key when a strange noise started.
