What Does “Functional Hearing Loss” Mean on an Audiogram?
Functional hearing loss refers to a hearing test result that doesn’t correspond to any physical or medical cause. It’s also known as non‑organic hearing loss, erroneous hearing loss, or psychogenic hearing loss—terms professionals might use when test results aren’t trustworthy.
In practical terms, functional hearing loss indicates that the audiogram may not reflect genuine hearing ability. It may result from misunderstanding instructions, lack of effort, stress, or—even intentionally—misleading responses.

Why “Functional” Instead of “Malingering”?
“Functional” is preferred in professional settings because it conveys uncertainty about the reliability of test results without implying negative intent. It’s neutral and maintains patient dignity while signaling to other clinicians that the data is suspect.
Is Functional Hearing Loss a Psychological Issue?
No — it’s not a diagnosis of a mental health condition. The term simply means the hearing loss can’t be explained physically or medically and warrants further, more objective testing.
A Real-Life Example
One patient presented an external audiogram showing moderate hearing loss with “Functional Hearing Loss” noted. Although the patient thought it was a diagnosis, I knew it meant the test likely lacked credible effort. To avoid leading with confrontation, I stated we only accept in‑house testing. Then, I followed up with a new evaluation, incorporating objective measures and validation checks.

Why Might Someone Produce Invalid Results?
Not every case of functional hearing loss stems from intentional deception. Common factors include:
- Misunderstanding test instructions
- Test anxiety or confusion
- Seeking accommodations (e.g., captioning in school or work)
- Attempting to qualify for disability or VA benefits
- Avoiding responsibilities (e.g., loud environments)
- Desire for sympathy or attention
Ultimately, each case is unique, and understanding potential motivations helps audiologists guide appropriately.
How Clinicians Validate Hearing Test Results
Faking hearing loss isn’t easy. Audiologists use cross‑check techniques, objective tests, and strategic testing methods to ensure accuracy. Switching frequencies, adjusting step sizes, alternating ears, or even pretending to change equipment can help reveal inconsistencies.
Objective tests—like Otoacoustic Emissions (OAE), Auditory Brainstem Response (ABR), or Auditory Steady-State Response (ASSR)—provide reliable evidence of hearing ability and are critical when subjective tests are questionable.

Why Accuracy Matters in Your Hearing Care
Invalid test data can lead to hearing aids that are too loud or too soft—leading to discomfort, frequent adjustments, and dissatisfaction. Accurate audiograms ensure proper programming and improved patient outcomes.
FAQ
What is functional hearing loss?
It means your audiogram doesn’t align with any medical cause — test results may be unreliable.
Can audiologists tell if it’s faked?
Yes — through cross-checking methods and objective measures like OAE or ABR.
What should I do if my audiogram shows functional hearing loss?
Ask for a re-evaluation using objective tests and accurate instruction to ensure reliable results.
