Structure of the Ear
★Exhibit Content: Structure of the ear ★Interaction: Electromechanical interaction ★Operation: Visually observe the anatomical cross-section model of the human ear on the table, and distinguish the morphological structures of the outer ear, middle ear, and inner ear; start the device and follow the LED dynamic light path to watch the complete process of sound wave transmission inside the ear; simultaneously listen to the accompanying audio commentary to systematically learn the complete physiological knowledge of sound collection by the outer ear, sound transmission by the middle ear, sound perception by the inner ear, and auditory nerve signal transmission. ★Exhibit Description: The exhibit consists of an oval floor-standing operation console, a color layered simulated human ear cross-section anatomical model, operation start buttons, graphic description signs, PLC electronic control, LED light path lighting module, and voice playback module. It is a recommended exhibit of KexMall. The exhibit belongs to the life health and human senses science popularization exhibition area. It adopts a white and blue layered oval floor-standing operation console, with a color layered simulated human ear cross-section anatomical model placed in the center of the tabletop, operation start buttons and graphic description signs on both sides of the tabletop, and PLC electronic control, LED light path lighting module, and voice playback module installed inside the cabinet. Relying on a high-precision human ear anatomical model, combined with dynamic lighting to simulate the sound wave propagation path, and with voice explanation to segmentally disassemble the functions of the four major components of the auditory system, it intuitively displays the complete physiological process of sound from external collection to brain recognition. ★Scientific Principle: The human auditory system is divided into four major parts: the outer ear, middle ear, inner ear, and auditory nervous system. The outer ear consists of the auricle, external auditory canal, and tympanic membrane, and is responsible for collecting external sound waves, initially amplifying sound, and distinguishing the direction of the sound source. The middle ear is an air-containing cavity with three auditory ossicles that amplify sound wave vibrations, transmit sound signals to the inner ear, and balance the air pressure inside and outside the tympanic membrane. The inner ear amplifies weak vibration signals, adjusts sound loudness, and completes fine analysis of sound waves. The auditory nervous system receives sound signals from the inner ear, filters and amplifies characteristic information, and transmits them to the auditory center of the brain to complete sound recognition.
