Keening

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

As the fog rolled in, a keening foghorn warned ships of the treacherous rocks ahead.

The horror movie was accompanied by a soundtrack of keening voices, adding to the creepy atmosphere.

The old graveyard was filled with the sound of keening voices as mourners gathered to pay their respects.

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