Hearing changes are common and often gradual. You may first notice difficulty following conversations in busy places, needing to turn the television up, or asking people to repeat themselves more often. These early signs can be easy to dismiss, yet they are important indicators that your hearing may need assessment.
Pure tone audiometry is the gold standard hearing test used worldwide to measure hearing sensitivity accurately. It is painless, structured and highly informative. Pure tone audiometry forms a core part of a full audiologist hearing assessment at The Forbury Clinic, helping us provide a clear and evidence-based hearing loss diagnosis. Identifying hearing changes early improves long-term outcomes and supports timely treatment.
What Is Pure Tone Audiometry?
Pure tone audiometry is a diagnostic hearing test that measures the quietest sounds you can hear at different pitches. In simple terms, it checks how sensitive your ears are to sound. Each ear is tested separately so that any difference between the two can be identified clearly.
The term “pure tone” refers to single-frequency sounds, rather than speech or complex noise. During the test, you will hear tones across low, mid and high frequencies. The results are plotted on a graph known as an audiogram. An audiogram explained in plain language shows which sounds you can hear easily and which require a louder volume.
Why Pure Tone Audiometry Is Important
Pure tone audiometry provides objective information about hearing function and plays a central role in modern audiology care.
One of its main strengths is early detection. Hearing loss often develops slowly, particularly age-related or noise-induced changes. Pure tone audiometry can identify hearing loss before it becomes severe, allowing earlier intervention and better long-term outcomes.
It also helps distinguish between different types of hearing loss. Conductive hearing loss occurs when sound cannot pass efficiently through the outer or middle ear, often due to fluid, infection or earwax. Sensorineural hearing loss involves the inner ear or hearing nerve and is commonly linked to ageing or noise exposure. Mixed hearing loss combines elements of both.
Understanding sensorineural vs conductive hearing loss matters because treatment differs. Conductive problems may respond to medical or surgical treatment, while sensorineural loss may require hearing aids or specialist monitoring.
The results of pure tone audiometry guide treatment decisions within a consultant-led pathway. Depending on findings, your care plan may include hearing aids, medical management, further imaging or regular monitoring. Our audiologist at The Forbury Clinic works closely with ENT consultants to ensure a coordinated and personalised approach.
What Happens During the Hearing Test?
Many patients feel anxious before a hearing test, particularly if it is their first private hearing test. Patients can rest assured that the procedure is straightforward, comfortable and entirely non-invasive.
Step 1: Preparation
You will be seated in a quiet, soundproof booth or dedicated testing room. Headphones or soft insert earphones are placed in your ears. The audiologist explains the hearing test procedure clearly and ensures you are comfortable before beginning. This standard hearing test approach is used in private hearing test settings across the UK. There are no needles, no invasive instruments and no discomfort.
Step 2: Listening to Sounds
You will hear tones at different pitches and volumes. Each time you hear a sound, you press a button or raise your hand. The audiologist gradually reduces the volume to determine the quietest sound you can detect. This level is called your hearing threshold. Each ear is tested separately to ensure accurate comparison.
Step 3: Bone Conduction Testing
In addition to headphones, a small vibrating device may be placed behind your ear. This measures how well sound travels directly to the inner ear, bypassing the outer and middle ear. Bone conduction testing helps differentiate between conductive and sensorineural hearing loss. You may feel a gentle vibration, but it is not painful.
Understanding Your Audiogram
After the test, your results are displayed on an audiogram. Understanding this graph helps you make sense of your hearing profile.
What the Graph Shows
On the audiogram, frequency or pitch is shown along the horizontal axis. Lower pitches are on the left, and higher pitches are on the right. Volume, measured in decibels, is shown on the vertical axis. The lower the number on the graph, the softer the sound you can hear, indicating better hearing sensitivity. An audiogram explained clearly allows you to see patterns, such as difficulty hearing higher frequencies.
Degrees of Hearing Loss
Hearing levels are categorised into degrees:
Normal: Able to hear soft sounds across most frequencies.
Mild: Difficulty hearing soft speech, especially in background noise.
Moderate: Conversations may need to be louder; group discussions become challenging.
Severe: Speech must be loud to be heard clearly.
Profound: Very limited hearing without amplification.
Understanding the degree of hearing loss helps determine the most appropriate management plan.
What Happens After Your Results
Once testing is complete, the audiologist explains your findings clearly. If hearing loss is identified, recommendations may include monitoring, hearing aids, referral to an ENT consultant, or further investigations. Our multidisciplinary team ensures that your audiologist hearing assessment is part of a coordinated care plan.
Who Should Consider Pure Tone Audiometry?
Pure tone audiometry is not only for those with obvious hearing loss. It is also a valuable preventative assessment.
You should consider booking a hearing test if you experience:
- Gradual hearing decline
- Persistent tinnitus
- Difficulty hearing in background noise
- A feeling of ear fullness
- Occupational noise exposure
- Recurrent ear infections
- A family history of hearing loss
Early assessment supports proactive management and protects long-term hearing health.
Is Pure Tone Audiometry Accurate?
Pure tone audiometry is regarded as the gold standard hearing threshold test. When performed correctly by a trained audiologist, it provides highly reliable information. The test does rely on patient participation, so clear communication between you and the audiologist is required.
It is often combined with additional tests such as tympanometry, which assesses middle ear function, and speech discrimination testing, which measures how well you understand spoken words. Together, these form a comprehensive audiologist hearing assessment.
Does the Test Hurt or Have Risks?
Pure tone audiometry is completely non-invasive. It does not involve radiation and carries no known risks. The test is safe for adults and older children. It usually takes between 20 and 30 minutes, depending on the complexity of the assessment.
Many patients discover how simple the experience is. There is no recovery time required and you can return to normal activities immediately afterwards.
When to Seek Urgent Advice
While gradual hearing changes are common, some symptoms require prompt medical attention:
- Sudden hearing loss
- Hearing loss affecting only one ear
- Severe dizziness or imbalance
- Persistent ear pain
If you experience any of these symptoms, seek urgent medical advice. Sudden hearing loss in particular requires immediate assessment.
Clear Hearing Starts With Clear Answers
Pure tone audiometry provides measurable, objective data about your hearing. It removes uncertainty and allows for an accurate hearing loss diagnosis. Early identification of hearing changes improves outcomes and supports appropriate intervention.
