Keening

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

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

The piercing sound of keening could be heard from miles away, signaling the loss of a respected community leader.

The young child stood by the graveside, keening for his pet dog that had passed away.

The keening smell of rotten eggs filled the kitchen, indicating a gas leak.
