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.
