 What does hatcher mean when he says, “to vibrate the atmosphere by means of resonating organs in his breathing passage.”
Whatever it was, he had no business in it; for five minutes before he had been spaceborne, on the Long Jump from Earth to the thriving colonies circling Betelgeuse Nine. This was ultrawave radio, something more than a million times faster than light, with a range measured, at least, in hundreds of light-years. Suppose you call him "Hatcher" (and suppose you call it a "him.") Hatcher, like McCray, was an adventurous soul, young, able, well-learned in the technical sciences of his culture. Hatcher's principal task at this moment was to run the "probe team" which had McCray under observation, and he was more than a little excited. "Paranormal powers," muttered Hatcher's second in command, and the others mumbled agreement. Hatcher ordered silence, studying the specimen from Earth. Hatcher hurried through the halls of the great buried structure in which he worked, toward the place where the supervising council of all probes would be in permanent session. Hatcher identified himself and gave a quick, concise report: "The subject recovered consciousness a short time ago and began to inspect his enclosure. "He then began to vibrate the atmosphere by means of resonating organs in his breathing passage. The staff is preparing a technical description of the forces now, but I can say that they are electromagnetic vibrations modulating a carrier wave of very high speed, and in turn modulated by the vibrations of the atmosphere caused by the subject's own breathing."
