Final answer:
Frequency theory, which suggests different areas of the basilar membrane are activated by different sound frequencies, aligns with the understanding that hair cells are sensitive to specific frequencies. Place theory and frequency theory explain different aspects of sound perception and neither theory alone provides a complete explanation of pitch perception.
Step-by-step explanation:
The statement that neither place theory nor frequency theory fully explains the adequate theory of the perception of sound is true. The place theory suggests that different parts of the basilar membrane respond preferentially to different frequencies; high-frequency sounds cause greater vibrations at the base, whereas lower frequencies peak further along the membrane. On the other hand, the frequency theory proposes that the rate of action potentials corresponds to the frequency of auditory stimuli, which explains the perception of lower frequencies but is inadequate for high frequencies due to the physiological limits on the rate at which hair cells can fire.Thus, the correct statement from the given options is: C) Frequency theory suggests that different sound frequencies activate different areas along the basilar membrane. This is supported by the understanding that hair cells are tuned to specific frequencies, and high frequency sounds stimulate the base of the basilar membrane while low frequency sounds travel further before stimulating the membrane.
