Uncovering the Truth: Understanding the Stenger Test - By Acoustik Hearing And Speech Clinic

When hearing results in one ear don't add up — inconsistent responses, unexpected asymmetry, or an unusually large gap between ears — the Stenger Test offers an objective way to check whether recorded thresholds truly reflect a patient's hearing.

What Is the Stenger Test?

The Stenger Test relies on the Stenger phenomenon: when identical tones play to both ears at once but at different volumes, a person can only consciously perceive the louder one. If someone is exaggerating or has a non-organic (functional) hearing loss, they may fail to respond when the louder tone is aimed at their "poorer" ear — because that's actually the ear they hear better, and the loudest tone reaching them goes unacknowledged.

Test Specifications

Duration: 10–15 min
Equipment: Two-channel calibrated audiometer, supra-aural or insert earphones (not bone conduction)
Preparation: Clear ear canal; conventional pure tone audiogram completed first
Setting: Sound-treated room at the clinic
Age Group: Adults primarily; used cautiously in children

Procedure of the Test

A conventional pure tone audiogram is obtained, noting inconsistent responses or unexpected asymmetry.
The frequency with the largest asymmetry is selected; baselines reconfirmed in both ears.
In the poorer ear, a tone is set 10–20 dB below threshold; in the better ear, 10–20 dB above threshold.
Both tones are presented simultaneously; response (or lack of one) is recorded.
Trial repeats for consistency; poorer ear's intensity rises in 5 dB steps while better ear stays fixed.
Process repeats at other clinically relevant frequencies as needed.

Why Is the Test Done?

Identifies a non-organic component in unilateral or asymmetric hearing loss
Recommended for a large gap between ears or inconsistent audiometry responses
Useful in medico-legal situations where motive to alter responses may exist
Guides need for objective testing (ABR, ASSR, OAE, acoustic reflexes) to clarify true status

What Will the Result Show?

Whether the patient responds to simultaneous tones as expected, or fails to respond despite the louder tone reaching the "poorer" ear.

Interpretation

Negative Stenger (button pressed): "Patient responded appropriately — not indicative of non-organic hearing loss. Consider further investigation or cross-check with independent measures."
Positive Stenger (no response): "No response despite the louder tone in the poorer ear — indicative of a non-organic component. Objective assessment (ABR, ASSR, OAE, or acoustic reflexes) recommended."

A positive result doesn't necessarily mean intentional exaggeration — it may reflect genuine psychological or social factors and should be discussed calmly and factually, with results recorded objectively and correlated with further testing where possible.The Stenger Test needs precise two-channel equipment and a controlled setting, so it's performed at our clinic.
