Study Notes

Inner Ear Structure

The inner ear, a crucial part of the hearing process, contains the cochlea, a complex structure within the labyrinth.
The labyrinth is comprised of a bony labyrinth surrounding a membranous labyrinth.
The membranous labyrinth contains the cochlear duct (also known as the corti), which houses the organ of Corti.
The cochlea possesses three chambers: scala vestibuli, scala media (cochlear duct), and scala tympani.

Sound Perception

Sound waves are characterized by their wavelength and wave height.
Shorter wavelengths correspond to higher-pitched sounds.
The height (amplitude) of the sound wave directly relates to its intensity (loudness), measured in decibels (a logarithmic scale).
