# Instrument Description The document describes the function of the inner ear, particularly the cochlea. It details the mechanics of sound transduction, from sound waves to electrical signals. The notes also discuss: * **Bone Conduction:** The transmission of sound through bone. * **Air Conduction:** The transmission of sound through the air. * **Cochlear Structures:** The various structures within the cochlea, such as the inner and outer hair cells (IHCs and OHCs), their connection to the tectorial membrane, and how they translate mechanical vibrations into electrical signals. * **Hair Cells:** The role of hair cells in converting mechanical vibrations into electrical signals. * **Frequency Discrimination:** The cochlea's ability to differentiate different sound frequencies. * **Auditory Pathway:** The transmission of the electrical signals from the cochlea to the central auditory system. The notes also seem to include some numerical data related to these structures, like the number of stereocilia, and other measurements. The notes also mention the concepts of Amplitude (intensity) and Frequency (pitch), of sound waves. There is a mention of "normal hearing range" ( likely a threshold, in dB). Lastly, it discusses the processing and interpretation of the information within the central hearing system.
