How far can a 100 decibel sound travel through the earth's atmosphere at sea level?

A 100-decibel sound can travel several kilometers through the Earth's atmosphere at sea level, depending on various factors such as frequency, humidity, and temperature. Generally, higher frequencies dissipate more quickly than lower frequencies, which can travel further. In ideal conditions, sound can travel up to about 10 kilometers, but obstacles and atmospheric conditions can significantly reduce this distance.
