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 young child stood by the graveside, keening for his pet dog that had passed away.

The old television emitted a high-pitched keening noise whenever it was turned on.
