Cacophony (kuh-kof-uh-nee) NOUN

1. harsh, discordant sound

The sounds of barking dogs and sirens added to the cacophony on the streets.
From Michael Berg:

Every person has a unique connection to the Creator that can never be extinguished, and every person has a great soul that can manifest important things in our world. To make a person feel less than they are because of something inside themselves, be it faith, race, or sexual orientation, is the greatest sin of all."
