Keening

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.

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

The haunting melody of the keening bagpipes played at the memorial service brought a sense of solemnity to the occasion.

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