Cochlea -- quality of filtering

How well does the cochlea divide sound into its frequency components?
For example, a 100 dB, 6000 Hz, pure tone, stimulates the hair cells
for 6000 Hz.  But does it avoid stimulating any 5000 Hz hair cells at
all, or does it stimulate those with a small fraction of the energy it
applies to the 6000 Hz hair cells?  Can anyone supply any kind of
formula for estimating how much stimulation there will be at different
frequencies when a single pure tone is applied?
