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

The abandoned puppy let out a keening howl, desperately yearning for someone to rescue it.

The wounded animal emitted a keening cry, pleading for help.

The keening howls of the wolf pierced the silence of the night.
