Abstract
In the group of 50 cochlea from 28 men aged 38-73 years a great variability in the
length of the cochlear duct was found ranging from 28.0 to 40.1 mm. The variability
in the number of inner and outer hair cells is not so prominent and the same holds
for the variability in density. Average densities of the inner and outer hair cells
decrease with increasing cochlear length. However, the long cochleae have a greater
number of hair cells which indicates that long cochleae have more sensory cells in
a given frequency region.
