Keening

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

The keening cries of the wounded soldier could be heard from the battlefield.

The old haunted house echoed with the keening cries of unseen spirits.

The air raid siren's keening pierced through the city, signaling imminent danger.

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

The injured bird emitted a keening cry, signaling its distress.

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