Sound transmission isn't limited to the "air vibration of the eardrum." Our bodies are intricate resonant cavities. Bone conduction, a seemingly niche principle of hearing, actually reveals a more direct auditory mechanism: when a sound source vibrates directly onto the skull, the vibration is transmitted through the bones (especially the temporal bone) to the cochlear lymph in the inner ear, stimulating the auditory hair cells to generate nerve signals, which the brain then recognizes as sound. This bypasses the outer ear and eardrum, allowing hearing to occur even in environments completely isolated from air conduction. Our interactive "bone conduction" exhibit allows you to experience this principle firsthand using a precise device measuring 1350*1350*850mm. Without headphones, simply follow the instructions to place specific contact parts in the corresponding positions on your skull. The device generates precisely controlled mechanical vibrations, simulating sound signals. You wil
