http://hyperphysics.phy-astr.gsu.edu/hbase/Audio/spk2.html WebLower frequency waves travel further as surface waves. They tend to follow the earth's curvature due diffraction and attenuation. Diffraction causes bending and is inversely proportional to the wave's frequency. Attenuation, along with energy loss, also makes the waveform to tilt downwards. This essentially helps in following the earth's curvature.
