Why is it called the 'silent river'?

The identity lies hidden within this river's name itself. It flows through such a region where human presence is virtually non-existent. There are no cities, no factories. As a result, only bird calls, forest sounds, and the gentle murmur of water can be heard here—it is this tranquility that earns it the name 'Silent River'.
