Who theorized the place theory?
A
Ernest Wever
B
Helmholtz
C
Charles Bray
D
None of the above
Explanation: 

Detailed explanation-1: -A theory of pitch perception first proposed in 1865 by the German physiologist, physicist, and mathematician Hermann Ludwig Ferdinand von Helmholtz (1821–94) according to which the perceived pitch of a tone depends on the position or place on the basilar membrane of the auditory receptors that transmit nerve impulses.

Detailed explanation-2: -The place theory is usually attributed to Hermann Helmholtz, though it was widely believed much earlier.

Detailed explanation-3: -Place Theory Helmholtz’ modern theory of hearing states that incoming sounds from the environment are, in a spectral representative form, extracted by the inner ear. The inner serves as a tuned resonator that passes the spectral representation to the brainstem, and then to the auditory cortex via the auditory nerve.

Detailed explanation-4: -Helmholtz suggested that the ear reintroduces energy at the fundamental by a process of distortion that produces energy at frequencies corresponding to the difference between two components physical present (i.e. at the harmonic spacing). Any pair of adjacent harmonics would generate energy at the fundamental.

Detailed explanation-5: -According to the place theory of hearing, we can hear different pitches due to specific sound frequencies causing vibrations in specific parts on the basilar membrane of the cochlea. In other words, different parts of the cochlea are activated by different frequencies.
