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 abandoned house stood in the distance, its broken windows and overgrown garden giving it a keening presence.

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

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