Bone Conduction

Understand the principle of bone conduction through the interactive process of placing the elbow in a designated position and hearing clear sounds. The exhibit mainly consists of players, bone conduction devices, etc. Press the start button, place your elbow in the designated position, or place your chin on the designated position to hear a very clear sound. This is because when the elbow or chin comes into contact with a metal piece, the vibration of the sound source is transmitted through the metal piece to the skull or jawbone, and then transmitted to the auditory nerve and brain, thereby feeling the sound. This sound transmission method is called bone conduction. Experiments have shown that the transmission of sound through the skull and jawbone is better than through air. Bone conduction headphones and hearing aids both utilize the principle of bone conduction. Target audience: Adolescents aged 6-15. Display format: Electromechanical interactive device operation instructions (audience experience) 1 Visitors press the start button to initiate interaction; 2. Visitors place their elbows on the vibrating platform or place their chin on it.

Interaction type: Interactive installation. The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

Bone conduction is a way in which sound waves are transmitted to the inner ear: sound waves directly pass through the skull, causing corresponding fluctuations in the external lymph nodes and stimulating the spiral organ of the cochlea to produce hearing. Bone conduction refers to the proliferation and elongation of oriented osteogenic precursor cells from the host bone surface and bone marrow around the implant bed into the surface of the implanted bone and its cavity, producing osteoblasts to form new bone. The external sound heard by the human ear is the vibration of the external air, which transmits the information of the sound to the auditory nerve through the eardrum. With the processing of the brain, it forms what we call hearing. And the sound we hear when we speak ourselves is transmitted directly from the skull to the auditory nerve through the vibration of the vocal cords, combined with the processing of the brain to form another type of hearing.
