Tympanic membrane modelprinciple:The tympanic membrane of the human ear can perceive sound waves from the outside world. The incoming sound waves cause the tympanic membrane to vibrate. After the vibration is transmitted to the inner ear, bioelectricity is transmitted to the brain, making people perceive the sound.Instructions:1. Make a sound at the simulated auricle and observe the change of the foam ball in the transparent cover in the model.2. Make sounds through different positions (far, near and different directions), and observe the changes of the foam balls in the transparent cover.

Features

• Material: PC plastic
• Size: 13*7.8*8.5cm/5.1*3*3.3in
• The tympanic membrane of the human ear can perceive sound waves from the outside world. The sound waves cause the tympanic membrane to vibrate. After the vibration is transmitted to the inner ear, it generates bioelectricity, which is transmitted to the brain and makes people perceive the sound.
