Stapedius
A self-contained, interactive guide to the Acoustic Reflex Test — the stapedial reflex in immittance audiometry. Built for students, trainees and clinicians who want to learn to read the reflex with confidence.

Introduction
What the acoustic reflex is, where it sits in the immittance battery, and how to use this atlas.
The AtlasAnatomy
The stapedius muscle, the ossicular chain, and the afferent and efferent limbs of the reflex arc.
The AtlasPhysiology
How stapedius contraction changes admittance — the consensual reflex and its protective role.
The AtlasTechnique
Probe placement, stimulus choice, threshold search, the response criterion and reflex decay.
The AtlasInterpretation
Probe-ear, stimulus-ear and diagonal patterns; the Metz test and the meaning of reflex decay.
InteractiveReflex Simulator
An interactive admittance-dip waveform with draggable onset and offset markers.
InteractiveComparison Tool
Place any two conditions side by side and see how their reflex signatures differ.
InteractiveClinical Cases
Worked cases — read the vignette, study the findings, and reason to a diagnosis.
InteractivePattern Trainer
An endless stream of reflex grids to classify, with graded feedback on every finding.
InteractiveSelf-Assessment
Twenty-four questions with browse, spaced-repetition and timed modes.
ReferenceGlossary
Concise definitions of the key terms, with aliases and cross-links.
ReferenceReferences
The peer-reviewed and authoritative sources behind every claim in the atlas.
The conditions
Each condition page pairs a narrative explanation with the characteristic reflex grid, audiogram, decay behaviour and citations.
