Examples:

"In recent years, an array of findings have also revealed an expansive nonhuman soundscape, including: turtles that produce and respond to sounds to coordinate the timing of their birth from inside their eggs; coral larvae that can hear the sounds of healthy reefs; and plants that can detect the sound of running water and the munching of insect predators. Researchers have found intention and meaning in this cacophony, such as the purposeful use of different sounds to convey information." — Sonia Shah, The New York Times, 20 Sept. 2023

Did you know?

If you’re hooked on phonetics, you may know that the Greek word phōnḗ has made a great deal of noise in English. Cacophony comes from a joining of phōnḗ ("sound" or "voice") with the Greek prefix kak- (from kakos, meaning "bad"), so it essentially means "bad sound." Other phat phōnḗ descendants include symphony, a word that indicates harmony or agreement in sound; polyphony, referring to a style of musical composition in which two or more independent melodies are juxtaposed in harmony; and euphony, a word for a pleasing or sweet sound. Kakos is responsible for far fewer English words, but one notable descendent is kakistocracy, meaning "government by the worst people," which, we'll be honest, doesn't sound great.
