Keening

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

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

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 keening shriek of the fireworks lit up the night sky.
