Research suggests this tonality is not stress-induced but results from a slight, measurable depression of the intrinsic pitch frequency (IPF) in the [laryng…

   Purring is a continuous, low-frequency vibratory sound produced by many species of Felidae, most notably the domestic cat(Felis catus). The sound is generated during both inhalation and exhalation, resulting in a characteristic rhythmic oscillation. Acoustically, purring occupies a narrow frequency band, typically ranging from $25$ to $150$ Hertz ($ \text{Hz} $), though specific vocalizations in captive Cheetahs(Acinonyx jubatus) have been recorded as low as $8.5 …
