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.

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

The lonely lighthouse emitted a keening beam of light that swept across the dark sea.

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

The chilling keening of the banshee sent shivers down the spines of those who heard it.
