Keening

The keening stench of decay emanated from the garbage dumpster, making it difficult to pass by.

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 women gathered in the cemetery, their voices intertwining in a mournful keening that honored the departed.
