Analyzing Cat Purring Frequency

Domestic cat larynges can produce purring frequencies without neural ...

Here we show that low- frequency phonation in the purring range (20-30 Hz) can readily be elicited in the excised larynges of domestic cats (Felis sylvestris catus) in the absence of muscular contraction or neural input. These low- frequency vocal fold vibrations involve a special vocal mode with an unusually long closed quotient, reminiscent of the "vocal fry" register in humans. 13 We ...

Domestic cats are small, with most weighing about 4.5 kilograms, and researchers had puzzled over how these animals manage to generate the low- frequency vocalizations—typically between 20 and 30 hertz (Hz)—involved in purring . Such frequencies are usually only observed in much larger animals, such as elephants, which have far longer vocal ...

As we can see from the illustration, Analyzing Cat Purring Frequency has many fascinating aspects to explore.

Domestic cat larynges can produce purring frequencies without neural ...

Cat purring has been assumed to be produced by centrally controlled cyclic contractions of intrinsic laryngeal muscles, but Herbst et al. now show that cat larynges can generate purring -like sounds via self-sustained vocal fold oscillation with no neural input. This indicates that cat purring dynamics are more complex than previously assumed.
