Handcrafted, anatomically accurate training model.

  • 5 times life-size
  • Made from durable vinyl plastic
  • Sagittally sectioned along the length of the auditory canal and Eustachian tube: it is easy to trace the path of sound waves entering the ear and how pressure is equalized on both sides of the eardrum

  • An air bubble in each will shift position when tilted, demonstrating the function of the canals in maintaining equilibrium (see picture)
  • A spiral cutaway of the cochlea shows its three canals in contrasting colors to teach the concept of pitch
  • 36 hand-numbered features are identified in the accompanying key
  • Freestanding
