Keening

The keening wail of the baby echoed through the nursery, causing concern among the caregivers.

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

The keening shriek of the fireworks lit up the night sky.

The keening tone of his voice conveyed the depth of his heartbreak.
