Keening

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

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

The patient lay in the hospital bed, his keening thoughts consumed by the desire to be healthy again.

The keening aroma of freshly baked bread wafted through the bakery.

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