Lowest frequency big cat roar

The big cat roar with the lowest frequency is that of the lion Panthera leo, native to Africa and Asia. A lion's roar is delivered in bouts, lasting up to 90 seconds, consisting of up to 50 calls with a fundamental frequency (F0) of 40 to 200 Hz. A 36–81-Hz roar of about 0.5 to 1.5 seconds in duration reaches sound pressure levels (SPL) of 114 dB at a distance of 1 m.

In comparison, the roar of the tiger P. tigris, often referred to as a "long-distance advertisement call", is uttered at an average fundamental frequency of 158 Hz (it ranges from 83 Hz to 246 Hz).
