The archived copy does not have complete data. The right tympanogram is noted as within normal limits, and acoustic reflexes are present bilaterally with no reflex decay.

The report describes the left tympanogram, shown below, as follows.

“Immittance results are essentially normal. The only abnormality was a wide tympanometric slope gradient in the left ear.  Multicomponent tympanometry indicates that the G component (conductance, related to aural resistance (the frictional component)) inexplicably peaks at about -150 daPa. The meaning of this finding is unclear.  It does not appear pathologic. The presence of acoustic reflexes in each ear supports the contention of normal middle ear function. A hearing aid evaluation is scheduled and annual hearing retesting is recommended to monitor the status of the left ear.”
