Ultraman Kochakao's hearing is 40 billion times that of humans

The classic special effects originator Ultraman still has a large number of fans today. As the most classic hero in the special effects world, he naturally has outstanding abilities. According to foreign media reports, scientists have calculated based on actual theories that Ultraman's hearing is 40 billion times that of humans.

•According to the analysis of "Fantasy Science Reader", in the special drama "Ultraman Return", Ultraman's hearing is described as "being able to hear a needle falling from 200 kilometers away". According to analysis, the maximum distance that humans can hear a needle falling is only 1 meter, from this we can infer how powerful Ultraman's ears are.

• Calculated purely from the listening distance, Ultraman is 200,000 times that of humans. However, the diffusion of sound waves is not infinite, but decreases exponentially. At a constant temperature of 15 degrees, it is about 340 meters per second, 1,200 kilometers per hour, and 200 kilometers takes 600 seconds. Calculated based on the disappearance rate of sound waves, Ultraman's hearing is 40 billion times that of humans.

•However, this raises another question. If there really was a human being calling for help 200 kilometers away and was heard by Ultraman, the 10 minutes it took for the sound to be transmitted plus the time it took Ultraman to rush over, the victim would probably have already died.
