What explains how we detect high and low pitches compared to mid-range pitches?

• A. Mid-range; high and low
• B. High and low; mid-range
• C. Mid-range and high; low
• D. Mid-range and low; high

Answer: (B)

The correct choice accurately reflects the way humans perceive different pitches of sound through distinct mechanisms in the auditory system. High pitches are detected by the place theory, which asserts that different frequencies stimulate different locations on the basilar membrane within the cochlea of the inner ear. Higher frequencies produce maximal stimulation at the base of the cochlea, which is closer to the oval window, leading to the perception of high pitches. Conversely, lower pitches are primarily detected through frequency theory, where the frequency of the sound wave correlates with the rate at which the auditory nerve fires. This means that lower frequencies produce slower firing rates, which can effectively convey the perception of lower pitches. Mid-range pitches, typically between the high and low frequencies, can be processed through both theories and are perceived through a combination of place and frequency coding. Thus, the differentiation in detection mechanisms supports how high and low pitches compare to those in the mid-range, which is explained by the distinct auditory processing paths for these sounds.
