The claim that perception of pitch depends on where the vibration occurs along the basilar membrane is known as B. place theory.
The place theory is the one that states that the perception of sound is determined by the place in which vibrations happen along the basilar membrane, which is found within the cochlear in the inner ear. In that way, the place theory makes reference to the way in which human receive and perceive sounds. It is believed that the one who developed this theory was Hermann Helmholtz, a German physician and physicist who was interested in understanding the phenomenon of pitch perception and lived during the nineteenth century.
