Keening

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

The abandoned graveyard was filled with the keening of the wind passing through the tombstones.

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

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

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