Tympanogram Types and Graph Generator: Our Tympanogram Types Generator and Tympanogram Graph Generator tool lets you plug in measured values—Static Acoustic Admittance (Compliance), Equivalent Ear Canal Volume, Peak Pressure, and Gradient—and instantly plot a smooth, labelled graph. You’ll see which ear you’re testing, overlay right vs. left if needed, and get visual cues for interpreting Type A, B, C, etc. It saves time, reduces manual plotting errors, and standardizes reporting.

Tympanogram Types Reference
Type A
Distinctive peak near atmospheric pressure, typical of normal patients and otosclerosis.
- • Compliance: Normal
- • Ear Canal Volume: Normal
- • Peak Pressure: Normal
- • Gradient: Normal
Type As
Type A with shallow peak, associated with otosclerosis or otitis media.
- • Compliance: Less than 0.3 ml
- • Ear Canal Volume: Normal
- • Peak Pressure: Normal
- • Gradient: Normal or less than 0.2
Type Ad
Type A with high peak, found in scarred/flaccid eardrums or ossicular interruptions.
- • Compliance: Higher than 1.75 ml
- • Ear Canal Volume: Normal
- • Peak Pressure: Normal
- • Gradient: Narrow (less than 0.2)
Type Add
Type A with off-scale peak, found in ears with ossicular discontinuities.
- • Compliance: Off-scale
- • Ear Canal Volume: Normal
- • Peak Pressure: Normal
- • Gradient: Absent
Type B
Flat across pressure range, characteristic of middle ear fluid, cholesteatoma, perforations, or obstructions.
- • Compliance: Normal to low (OM) or Flat (Perforation)
- • Ear Canal Volume: High (Perforation) or Normal (OM)
- • Peak Pressure: No peak
- • Gradient: Wide (OM) or Absent (Perforation)
Type C
Negative pressure peaks beyond –100 daPa, associated with Eustachian tube disorders or middle ear fluid.
- • Compliance: Normal
- • Ear Canal Volume: Normal
- • Peak Pressure: Below -100 daPa
- • Gradient: Normal

Step-by-Step Guide to use Tympanogram Types and Graph
We’ve designed the interface to be, well, a breeze. Please refer to the attachment screenshot as you follow these steps.
Step 1: Input Measurement Values
- Static Acoustic Admittance (Compliance) in ml
- Equivalent Ear Canal Volume in ml
- Peak Pressure in daPa
- Gradient
Tip: Always calibrate your tympanometer first, and ensure the probe tip seals the ear canal completely. A leak throws off the Equivalent Ear Canal Volume reading.
Step 2: Select Ear
Click “Right Ear” or “Left Ear” tab. The active tab highlights in blue, so you won’t mix up sides.
Step 3: Generate Graph
Hit the “Generate Tympanogram” button. In less than a second, the tool plots your compliance curve (red for right, blue for left). The area under the curve can be shaded for easy visualization.
Step 4: Save or Export Results
Click the download icon or right‑click the graph to save as PNG. You can embed it directly into your patient report. No more fiddling with Excel or photo editors.
