Actually, there seems to be a slight misunderstanding in your statement. The auditory system's articulation does not involve the transmission and processing of sound information at each stage. The articulation process in the auditory system refers to the production of speech sounds by manipulating the vocal tract, including the tongue, lips, vocal cords, and other speech-related organs.
However, you are correct in describing the process of hearing new audition and sound perception, which involves the precise transmission and processing of sound information in the auditory system. Let's break down the process step-by-step:
1. Sound Collection: The auditory process starts with the outer ear collecting sound waves from the environment. The visible part of the outer ear, called the pinna, helps to capture sound and funnel it into the ear canal.
2. Sound Amplification and Transmission: The collected sound waves then travel through the ear canal and reach the middle ear. In the middle ear, the sound waves cause the eardrum (tympanic membrane) to vibrate. These vibrations are then transferred to three tiny bones in the middle ear: the malleus, incus, and stapes (commonly referred to as the hammer, anvil, and stirrup, respectively).
3. Inner Ear and Sound Conversion: The vibrations are amplified further by the three bones in the middle ear, and they are transmitted to the inner ear through the oval window, a membrane-covered opening. The inner ear contains the cochlea, which is a spiral-shaped, fluid-filled structure. The vibrations in the fluid of the cochlea cause tiny hair cells within it to bend.
4. Electrical Signal Generation: As the hair cells bend, they convert mechanical vibrations into electrical signals, essentially encoding the sound information in the form of neural impulses.
5. Neural Pathway: These electrical signals are then sent as nerve impulses through the auditory nerve (cochlear nerve) to the brainstem and further to the auditory cortex in the brain's temporal lobes.
6. Sound Perception: In the auditory cortex, the brain processes and interprets the electrical signals, allowing us to perceive and understand the sound information.
It's important to note that while articulation is related to the production of speech sounds, it is a separate process from hearing and sound perception. Both processes are essential for effective communication and understanding of spoken language.
