Keening

The keening screech of the brakes startled the pedestrians on the sidewalk.

The abandoned puppy let out a keening howl, desperately yearning for someone to rescue it.

The keening of the steam whistle signaled the departure of the train from the platform.

The wounded animal emitted a keening cry, pleading for help.

The mournful keening of the women in black veils set a somber tone for the entire funeral procession.

The keening howls of the wolf pierced the silence of the night.
