Giant Student Version Ear

This three-part ear replica exposes the entire length of the ear canal and Eustachian tube so that the sound waves entering the ear can be easily traced and to demonstrate how air pressure on both sides of the eardrum is equalized.   The hammer, anvil, transparent ear drum, and the labyrinth all lift out for hands-on study.  Functions of the 18 hand-numbered primary features are explained in depth in the accompanying study guide.  Overall dimensions are 16 x 11 x 7 inches (41 x 28 x 18cm).

Manufactured in the U.S.A. by Denoyer-Geppert.
