Auditory system is the biological and neural network responsible for the reception, transmission, and central processing of acoustic stimuli, enabling hearing and the perception of sound. As an academic concept and research field, its study investigates the intricate anatomical structures (from the outer ear to the auditory cortex), physiological mechanisms (transduction, signal coding), and neural pathways involved in auditory function, holding significance for understanding sensory biology, communication, and the basis of auditory disorders.
