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.
Parameters
Classification: Type A
Normal middle-ear pressure and mobility.
| Parameter | Value | Normal range | Status |
|---|---|---|---|
| Peak pressure (daPa) | 0 | -100 to 50 | Within range |
| Static admittance (mmho) | 0.7 | 0.3 to 1.6 | Within range |
| Tympanometric width (daPa) | 80 | 50 to 110 | Within range |
| Ear-canal volume (cm³) | 1.1 | 0.6 to 2 | Within 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.
