Low-Frequency Sounds: Low-frequency sounds are characterized by sound waves that vibrate at a slower rate, producing deep tones. They have fewer cycles per second (hertz) compared to high-frequency sounds.
Place theory suggests that different areas along the basilar membrane within the cochlea respond to specific frequencies of sound. Each area acts as its own "home base" for processing different pitches.
The volley principle proposes that groups of neurons take turns firing in rapid succession to achieve a combined frequency response exceeding their individual firing rates. This allows us to perceive certain frequencies even if individual neurons cannot fire fast enough on their own.
