The old projector whirred as it projected flickering images across the wall.

The steady whir of the old fan filled the small bedroom all night.

The old ceiling fan began to whir as the summer heat set in.

The steady whirring in the workshop made it hard to hear the conversation.

The whirring fan cooled the room on a hot afternoon.

The old ceiling fan, whirring softly above us, lulled the room into a sleepy calm.

The workshop filled with mechanical whirs as the machines started up.

The whirrings of the old projector filled the darkened room, mingling with the audience's quiet gasps.
