Keening

As the fog rolled in, a keening foghorn warned ships of the treacherous rocks ahead.

The old haunted house echoed with the keening cries of unseen spirits.

The old graveyard was filled with the sound of keening voices as mourners gathered to pay their respects.

The abandoned graveyard was filled with the keening of the wind passing through the tombstones.

As the funeral procession passed by, the sound of keening echoed through the streets.

The old television emitted a high-pitched keening noise whenever it was turned on.
