Keening

The keening cries of the wounded soldier could be heard from the battlefield.

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

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

The refugee glanced back at his war-torn homeland with keening eyes, filled with longing for a peaceful life.

The air raid siren's keening pierced through the city, signaling imminent danger.
