Tympanogram Section of Printout
The tympanogram is a graph which records the admittance of the ear as
a function of air pressure.
Data Section of Printout
The data section displays numeric values for the four key characteristics
of the tympanogram:
• Peak Ya — the compensated static acoustic admittance (height) of
the peak, measured in acoustic millimhos (mmho).
• Gradient (GR) — the width of the tympanogram; the distance across
the tympanogram measured at a height 50% down from the peak,
measured in decapascals (daPa).
• Tympanic Peak Pressure (TPP) — where the tympanometric peak
occurred on the pressure axis, measured in decapascals (daPa).
• Volume of the Ear Canal (Vea) — acoustically-determined ear canal
volume, measured in cubic centimeters (cc) at +200 daPa.
