Tympanogram Simulator

Adjust the four parameters — or drag the peak marker directly on the trace — and watch the Jerger classification and normative checks update live. The shaded box marks the adult normative region.

ParameterValueNormal rangeStatus
Peak pressure (daPa)0-100 to 50Within range
Static admittance (mmho)0.70.3 to 1.6Within range
Tympanometric width (daPa)8050 to 110Within range
Ear-canal volume (cm³)1.10.6 to 2Within range

Tip: a flat trace (drop static admittance toward zero) classifies as type B — then change the ear-canal volume to see how effusion, occlusion and perforation are told apart.
