Definitions:

Sine Waves

Mathematical curves that describe a smooth, periodic oscillation, often used to model wave-like phenomena in various fields including physics and engineering.

Cochlea

A spiral-shaped, fluid-filled inner ear structure essential for converting sound waves into nerve impulses, which are then transmitted to the brain for auditory perception.

Proximal Stimulus

The stimulus registered by the sensory receptors, e.g., the pattern of light falling on the retina.

Hair Cells

The auditory receptors in the cochlea, lodged between the basilar membrane and other membranes above.
