The college workforce carefully tested the audio spectrum of the tough, extra pressing purrs and located a unusual correlation. They spotted a top within the 220–520-hertz frequency vary inside the a lot decrease frequencies of standard purring. This frequency is equal to that of a child’s cry. The pressing, tough frequency of crying small children has a frequency vary of 300–600 hertz, triggering a human’s nurturing intuition.

Sure, astounding as it’s going to sound, the frequency at which cats purr—about 25 to 150 hertz—can have therapeutic houses, together with bone and tissue regeneration across the 25 and 50-hertz levels. Within the wild, cats spend numerous time laying round ready to seek and would possibly purr to stay their bones from going brittle from inaction. This tactic used to be even proposed by way of researchers to strap vibrating plates to the toes of astronauts to retain bone density whilst in area.
