Auditory Steady-State Response

Objective, frequency-specific estimation of hearing threshold — anatomy, recording technique and clinical interpretation, taught interactively.

The Auditory Steady-State Response (ASSR) is an electrophysiological response evoked by amplitude- or frequency-modulated tones. Because the response can be detected by automated statistical algorithms and is frequency-specific, ASSR has become a central tool for estimating hearing thresholds — particularly in infants and patients who cannot complete behavioural audiometry.

This atlas builds that picture in layers. Use the Reading level control in the sidebar to switch between Foundation, Trainee, and Clinician depth.

Practice & assessment

Once the fundamentals are in place, the clinical cases, pattern trainer, comparison tool, and self-assessment quiz let you test interpretation against worked examples. Your progress is saved locally in this browser and surfaced on the progress dashboard.
