Altman, the founder of classic close-up photography, still has a large number of fans today. As one of the most classic leather bag heroes in the close-up industry, nature itself has outstanding ability. recently, according to foreign media reports, scientists calculated based on practical theory that Altman's hearing is 40 billion times that of human beings**
• according to the analysis of Utopian Science Reader, in the special film "return of Altman", Altman's hearing is described as "being able to hear a needle falling 200 kilometers away". According to the analysis, the limit distance that humans can hear a needle falling is only 1 meter, so we can calculate how powerful Altman's ears are.
• in terms of listening distance alone, Altman is 200000 times that of human beings. However, the diffusion of sound waves is not infinite, but the reduction of geometric progression. Under the condition of constant temperature of 15 degrees, it is about 340 meters per second, 1200 kilometers per hour and 600 seconds for 200 kilometers. In terms of the disappearance rate of sound waves, Altman's hearing is 40 billion times that of human beings.
• however, this leads to another problem. If a human cries for help 200 kilometers away and is heard by Altman, the 10 minutes of the voice and the time it takes Altman to get there, it is estimated that the victim has already returned.
