Academician I. V. Obreimov began his explanation of one-sided hearing this way: "...Fishermen can't stand to be approached and talked to. And they're right. The fish in the water can hear conversations on shore just fine. And we, on shore, can't hear "fish talk." The fact is that as we move from air to water and from water to air, the energy of the sound stream" (William Bragg. The World of Sound. M.: Science, 1965. p. 333). Continue the explanation and back it up with quantitative estimates, assuming that humans respond to pressure fluctuations starting at about the same amplitude as fish.
