5 Types of Hearing Tests and What Each One Detects

The Short Answer

The five main hearing tests are pure-tone audiometry, speech audiometry, tympanometry, otoacoustic emissions (OAE) and auditory brainstem response (ABR) — each examining a different part of the hearing pathway. Pure-tone audiometry, the cornerstone test, maps the softest sounds you can detect across frequencies from roughly 250 to 8,000 Hz on an audiogram.

At a Glance

Key Takeaways

  • Pure-tone audiometry maps the softest sounds you can hear across frequencies, producing a graph called an audiogram.
  • Speech audiometry checks how clearly you understand and repeat words, not just whether you hear sound.
  • Tympanometry checks the middle ear and eardrum movement, spotting fluid, eustachian tube issues or perforations.
  • OAE testing gauges inner-ear (cochlea) health, while ABR measures how sound travels along the nerve to the brain.

Hearing isn’t something most people think about until something feels off – when sounds start to dull, conversations become harder to follow, or certain tones simply vanish. That’s when a hearing test shifts from being optional to essential. Yet, it’s not a one-size-fits-all process. Audiologists rely on a range of tests, each built to uncover something different about the way our ears and brains process sound. Understanding these methods can help you make sense of what’s happening and, more importantly, what to do next.

What Makes Hearing Tests So Varied?

Because hearing loss has many causes and patterns, no single test captures everything. Some tests measure the inner ear's ability to generate or send signals, while others assess how the brain interprets sound. Audiologists combine the results — thresholds, speech clarity, middle-ear function and nerve response — to build a complete picture of your auditory health.

Not only is hearing loss complex, but its causes and patterns vary dramatically from person to person. Some tests focus on the inner ear’s ability to send signals, while others measure how well the brain interprets those signals. It’s rarely just about volume – clarity, pitch, and even the presence of subtle distortions matter. By combining results, audiologists get a complete picture of your auditory health.

Pure-Tone Audiometry

Pure-tone audiometry is the cornerstone of hearing assessment, often the first test you’ll encounter. It works by measuring the softest sounds you can detect across different frequencies, from low bass notes to high-pitched tones. Through headphones, a series of tones plays at various volumes and pitches. You simply indicate when you hear them. The outcome – a detailed graph called an audiogram – maps your hearing thresholds.

This test is particularly effective at detecting sensorineural hearing loss, which stems from damage to the inner ear or auditory nerve. If you’ve ever struggled to hear conversations in noisy environments, this might reveal why.

Speech Audiometry

While pure-tone tests show thresholds, they don’t tell you how well you understand speech. That’s where speech audiometry steps in. It measures your ability to recognise and repeat words at different volumes. Why does that matter? Because real-world hearing isn’t about isolated beeps – it’s about voices, accents, and background noise competing for attention.

Not only does this test reveal how clearly you process speech, but it also highlights potential issues with word recognition. Someone might hear sound but struggle with comprehension, and this distinction can completely change the treatment approach.

Tympanometry

Tympanometry examines the middle ear, checking how well the eardrum moves in response to pressure changes. The test involves a small probe creating gentle air pressure variations, producing a graph called a tympanogram. It’s quick, painless, and surprisingly revealing.

What does it detect? Conditions like fluid build-up behind the eardrum, eustachian tube dysfunction, or even perforations. These issues aren’t always about permanent hearing loss; they can be temporary or treatable once the underlying cause is addressed.

Otoacoustic Emissions (OAE) Testing

The inner ear, specifically the cochlea, produces faint sounds of its own when stimulated. OAE testing measures these tiny emissions using a sensitive microphone. If the emissions are absent or reduced, it suggests damage to the hair cells responsible for converting sound into electrical signals.

This test is often used for newborn hearing screenings, but it’s equally valuable for adults. It’s particularly good at identifying early-stage hearing loss before symptoms become noticeable – something pure-tone tests might miss.

Auditory Brainstem Response (ABR)

ABR testing takes things further by measuring how the auditory nerve and brainstem respond to sound. Small electrodes placed on the head track neural activity as you listen to clicks or tones. It’s a more technical, in-depth method, often used when other tests leave questions unanswered.

Not only is ABR essential for diagnosing neurological conditions that affect hearing, but it also helps determine if the auditory nerve is transmitting signals correctly. This makes it a crucial tool for both children and adults with unexplained hearing challenges.

How Do These Tests Connect to Hearing Care?

Together they identify the type and degree of hearing loss, which guides what happens next — hearing aids, medical treatment or ongoing monitoring. The right combination depends on your symptoms, age and lifestyle. Crucially, a HCPC-registered audiologist interprets the results, turning technical graphs into clear, personalised guidance rather than just a report.

Choosing the right test isn’t guesswork – it depends on symptoms, age, and even lifestyle factors. For someone asking is hearing loss reversible, these tests form the foundation of the answer. They pinpoint the type of hearing loss, its severity, and the best path forward, whether that involves hearing aids, medical treatment, or ongoing monitoring.

And while the tests themselves are technical, the process of interpreting them is just as critical. That’s why working with expert-led hearing care services ensures you’re not just handed a report but given real, actionable guidance.

Final Thoughts

Hearing tests aren’t interchangeable checkboxes – they’re precision tools designed to uncover specific details about your auditory health. Pure-tone audiometry measures thresholds, speech audiometry reveals clarity, tympanometry checks mechanical function, OAE testing looks at inner-ear health, and ABR examines how sound travels to the brain. Together, they provide a complete map of where issues may lie.

So if your hearing feels off, don’t assume it’s just part of getting older – and remember that understanding the 5 types of hearing tests can help you ask the right questions and get the right answers.

Patient Questions

Frequently Asked Questions

What are the 5 types of hearing tests?

The five are pure-tone audiometry, speech audiometry, tympanometry, otoacoustic emissions (OAE) testing and auditory brainstem response (ABR). Each looks at a different part of the hearing system, from the middle ear and cochlea to the nerve pathway to the brain. Audiologists often combine several to build a full picture.

Which hearing test is done first?

Pure-tone audiometry is usually the starting point and the cornerstone of a hearing assessment. It measures the softest tones you can detect across a range of pitches and plots them on an audiogram, showing the degree of any hearing loss. Other tests are added depending on what it reveals.

What is the difference between pure-tone and speech audiometry?

Pure-tone audiometry measures the quietest sounds you can hear at each frequency, while speech audiometry measures how well you actually understand words. Someone can hear sound yet still struggle to make out speech, and this distinction can change the recommended treatment.

What does a tympanometry test check?

Tympanometry assesses the middle ear by measuring how your eardrum moves in response to gentle pressure changes, producing a graph called a tympanogram. It can reveal fluid behind the eardrum, eustachian tube dysfunction or a perforation — problems that are often temporary or treatable.

Why is OAE testing used for newborns?

Otoacoustic emissions testing measures faint sounds produced by the cochlea's outer hair cells, so it is quick, painless and needs no active response — ideal for babies. It is a routine part of newborn hearing screening and can also flag early hearing changes in adults before they show on an audiogram.
