The Majestic Roar of Lions and What It Tells Us

Lions have the loudest roar of all the big cats. The roar is so loud it can be heard up to 5 miles away and reaches 114 decibels (at a distance of around one meter). To put that into perspective, the human pain threshold is at around 110 decibels. So, standing too close to a roaring lion could not only send shivers down your spine but also be physically painful.
