Tympanometry Atlas
An interactive teaching atlas of impedance audiometry. Learn how the middle ear responds to changing pressure, why each tympanogram shape means what it means, and how to read the trace alongside acoustic reflexes and the audiogram.
Start here
New to immittance testing? Begin with the Introduction, then work through the anatomy and the physics of admittance before reaching the interpretation modules.
What's inside
Six learning modules — introduction, anatomy and physiology, the technology, method and technique, reading the tympanogram, and acoustic reflexes.
Interactive tympanogram simulator — drag the peak, adjust pressure, amplitude, width and ear-canal volume, and watch the Jerger classification update live.
Disease atlas — tympanometric signatures for effusion, perforation, Eustachian tube dysfunction, otosclerosis, ossicular discontinuity, and retrocochlear lesions.
Practice — clinical cases, a pattern-recognition trainer, and a tagged self-assessment quiz, with progress saved locally on your device.
How to use it
Everything here is built to be explored. Use the simulator to develop an intuition for the trace, then test that intuition against the clinical cases and the quiz. Every page can be printed or saved as a PDF, and the whole atlas compiles into one document via Print all.
