New Study: What Makes Rooster Crowing So Annoying?

Have you ever wondered what the most annoying sound in the world is? If you live in the countryside or have neighbors with chickens, you might say it's a crowing rooster. Researchers have developed an objective measure to determine the annoyance of a rooster's crowing. There is a frequency range between two to four kilohertz, and that is the range in which we hear particularly well. And if sounds in this range have high components, we often perceive them as very annoying, Prof. Christoph Reuter, Musicologist.
