Keening

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

The old haunted house echoed with the keening cries of unseen spirits.

As the funeral procession passed by, the sound of keening echoed through the streets.

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

The lonely lighthouse emitted a keening beam of light that swept across the dark sea.
