Tympanometry And Acoustic Reflexes
Tympanometry is particularly important should the audiogram suggest a conductive component from ear drum perforation, middle ear fluid or scarring as it may be amenable to medical or surgical treatment. Tympanometry measures the mobility of the ear drum. A small probe is placed in the ear canal and the pressure is varied whilst the amount of reflected sound energy is being measured. This provides a picture and numerical data of the condition of the ears sound conducting mechanism.
