Yelling is a loud vocal expression often used to convey strong emotions such as anger, excitement, or urgency. It involves projecting one's voice at a higher volume than normal speaking. People may yell to communicate over long distances, to get someone's attention, or to express frustration. Yelling can have various effects on both the person yelling and the listener. It may lead to increased adrenaline and heightened emotions for the person yelling, while the listener might feel startled or anxious. In some situations, such as during sports events or emergencies, yelling can serve as a useful tool for communication.
