Numerical atrophy of the hair cells of the organ of Corti of the inner ear in a 14-year-old tiger and a 17-year-old jaguar is described. The decrease in number of sensory hair cells is considered to represent physiological atrophy caused by the process of ageing. The findings are compared with previous observations on man, guinea-pigs, shrews, and bats. The development of the physiological involution of the hearing neuro-epithelium is discussed. 
Functional anatomy of the middle and inner ears of the red fox, in comparison to domestic dogs and cats
TLDR
Overall, the ear structures of foxes, dogs and cats are anatomically very similar, and their behavioural audiograms overlap, however, the results of several published models and correlations that use middle and inner ear measurements to predict aspects of hearing were not always found to match well with audiogram data, especially when it came to the sharper tuning in the fox audiogram.

The Sensory Biology of the Red Fox - Hearing, Vision, Magnetoreception
This study deals with the sensory systems of the red fox, more specifically with audition, vision, and magnetoreception. In the first chapter, I present the behavioural audiograms of three red foxExpand
The Adapted Ears of Big Cats and Golden Moles: Exotic Outcomes of the Evolutionary Radiation of Mammals
TLDR
A number of auditory “inventions” brought about through natural selection in two phylogenetically distinct groups of mammals are considered, the largely fossorial golden moles and the carnivorous felids of the genus Panthera along with its taxonomic neighbor, the clouded leopard. Expand
Probing cochlear tuning and tonotopy in the tiger using otoacoustic emissions
TLDR
Results imply that cochlear tuning in the tiger is significantly sharper than in domestic cat and appears comparable to that of humans, and data indicate that tigers have a larger tonotopic mapping constant than domestic cats. Expand
