Why Sound Travels Farther on Cool Nights — Temperature Layers Explained
IN · Published Jan 10, 2026
• Temperature inversion, where cool air is near the ground and warmer air is above, causes sound waves to bend back towards the surface.
• Sound travels faster in warmer air, leading to the refraction of sound waves during temperature inversions.
• Understanding temperature inversions helps explain why sounds seem to carry farther on cool, clear nights.
