Keening

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

The keening wail of the baby echoed through the nursery, causing concern among the caregivers.

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 keening tone of his voice conveyed the depth of his heartbreak.
