Sorry Martin, Don and jbv,

but I think you ALL are wrong and right at the same time.

The inner ear is a kind of a "mechanical" fourier analysis - device. The

cochlea of the inner ear consists of two parallel tubes, 
filled with lymphatic fluid. The upper one is the scala vestibuli,
the lower one the scala tympani. At the end of the two tubes, there
is a connection between them.
The eardrum, which is moved by the sound, passes the vibration 
on to the inner ear and to the scala vestibuli. As lymphatic fluid
is not comressible, the movement will be carried thru the whole
scala vestibuli and tympani and ends on a membrane in the middle ear
(where the little bones are !) called "round window". 
Well, the point is : Each frequency (sine wave) causes a specific
resonant
"standing" wave at a very specific distance from the beginning of the
scala
vestibuli. Thus, 4 Sine waves with different frequencies will produce
4 resonant waves in the inner ear. Between Scala vest. and tympani are
 hair cells, connencted to the brain via nerves. Vibration causes nerve
impulses. So you can say :
each hair-cell represents a very specific frequency. Thats frequency
analysis !
So, the ear does not care about curves, but only about frequencies.
The BRAIN "calculates", what you really hear ("Thats a Moog LP filter!
AAh, 
and thats EDP WASP lowpass!"). 
It is correct, that the human ear is "built" for frequencies in the 
speech frequency. The middle ear "bones" (How do you say in english?)
are built for these frequencies. Take a dolphin or a bat, they can hear
ultrasound and they have much more complex "mechanical transduction
mechanisms" for transmitting the sound to the inner ear.

Sorry for that Blah blah, but i am an anatomical pathologist.

PS: What the brain does with these frequencies is a field of
neurophysiology. And very very very complex.
