About This

• Intuitive Sound Vibration Display: Produce sounds from different positions (near, far and various directions), and clearly observe the dynamic changes of the foam balls inside the transparent cover to visualize sound transmission.
• High-Quality PC Material: Made of durable PC plastic with high transparency and sturdy structure, wear-resistant and suitable for long-term repeated demonstration and experimental use.
• Simulated Auricle Sound Testing: Make sounds toward the simulated auricle, and directly watch the vibration changes of the foam balls in the model’s transparent cover to show the tympanic membrane’s response to sound waves.
• Compact Portable Size: Measuring 137.88.5cm/5.133.3in, the model is small in size, easy to store and carry, ideal for laboratory and teaching display scenarios.
• Clear Auditory Mechanism Presentation: It truly restores how the human ear tympanic membrane senses external sound waves and vibrates, helping to understand the complete process of sound transmission and perception.
