Keening

The keening sound of the ambulance pierced through the silence of the night.

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 aroma of freshly baked bread wafted through the bakery.

As the funeral procession passed by, the mourners let out keening wails of grief, filling the air with a somber atmosphere.
