This is an objective test of your middle ear function and is useful for determining whether:

  • there is any fluid or congestion in your middle ear
  • there is a perforation (hole) in your eardrum
  • the eardrum is flaccid and weak
  • there is loss of continuity of the ossicles (middle ear bones) by disease or trauma
  • a grommet is blocked
  • changing pressure in the ear canal causes dizziness indicating a fistula (defect) in the bone surrounding the labyrinth (balance organ)


You are not required to do anything for this test other than sit very still. The audiologist will hold a soft rubber probe at the entrance of your ear canal and you may feel a slight change of pressure in your ear.
