Standard Hearing Test

What Is a Standard Hearing Test?

A standard hearing test — known clinically as pure tone audiometry (PTA) — is the cornerstone of hearing health care in the UK. It is the most widely used method for measuring how well you hear across a range of pitches (frequencies) and loudness levels (decibels). During the test, a qualified audiologist plays a series of tones through calibrated headphones while you sit in a soundproofed booth or quiet room. Each time you hear a tone, you press a button or raise your hand. The quietest level at which you can detect each tone is recorded as your hearing threshold at that frequency.

The test typically covers frequencies from 250 Hz (a low rumble) to 8,000 Hz (a high-pitched whistle), spanning the range most important for understanding speech. It is completely painless, non-invasive, and takes around 30 to 45 minutes including the consultation before and after. Whether you are booking your first ever hearing check or returning for a routine review, a standard hearing test is the single most informative assessment of your auditory health.

How Audiograms Work — Understanding Your Results

The results of pure tone audiometry are plotted on a chart called an audiogram. Frequency (pitch) runs along the horizontal axis from low to high, and intensity (loudness) runs down the vertical axis from soft to loud. Each ear is tested separately, and the thresholds are marked with symbols — typically O for the right ear and X for the left. The resulting pattern shows your hearing profile at a glance.

Your audiologist will use the audiogram to classify the degree of any hearing loss:

• Normal hearing: 0–20 dB HL — you can hear quiet sounds without difficulty
• Mild hearing loss: 21–40 dB HL — soft speech and background sounds may be missed
• Moderate hearing loss: 41–70 dB HL — conversational speech is difficult without amplification
• Severe hearing loss: 71–90 dB HL — only loud sounds and speech are audible
• Profound hearing loss: 91+ dB HL — most sounds are inaudible without powerful hearing aids or cochlear implants

The audiogram also reveals the configuration of hearing loss — whether it is flat across all frequencies, sloping (worse at higher pitches, the most common pattern in age-related loss), rising, or notched (a dip at a specific frequency, often seen in noise-induced hearing loss). Understanding your audiogram is the first step towards effective management. Our guide to reading audiograms explains every detail in plain English.

Types of Hearing Loss Detected

A standard hearing test, particularly when combined with bone conduction testing, can identify three main types of hearing loss:

• Sensorineural hearing loss — caused by damage to the inner ear (cochlea) or auditory nerve. This is the most common type in adults and is usually permanent. Causes include ageing, prolonged noise exposure, genetics, and certain medications. It is typically managed with hearing aids.
• Conductive hearing loss — caused by a blockage or structural problem in the outer or middle ear that prevents sound from reaching the inner ear. Common causes include ear wax build-up, glue ear, ear infections, perforated eardrum, and otosclerosis. Many conductive causes are treatable with medication or surgery.
• Mixed hearing loss — a combination of sensorineural and conductive components, requiring assessment of both before deciding on the best treatment approach.

Additional tests such as tympanometry and otoacoustic emissions may be performed alongside pure tone audiometry to build a complete diagnostic picture. If you struggle specifically with hearing in noisy environments, a speech-in-noise test can assess this dimension of your hearing that a standard audiogram may not fully capture.

Hearing Loss in the UK — The Scale of the Problem

Hearing loss is one of the most prevalent health conditions in the United Kingdom, yet it remains significantly underdiagnosed and undertreated. Key statistics paint a stark picture:

• An estimated 12 million adults in the UK — roughly one in five — have some degree of hearing loss, according to the RNID (Royal National Institute for Deaf People).
• Age-related hearing loss (presbycusis) affects approximately 71% of people over 70 and around 42% of those over 50, as reported by the British Society of Audiology (BSA).
• Despite the prevalence, the average person waits ten years from first noticing hearing difficulty to seeking professional help — a delay that research increasingly links to poorer outcomes.
• Only around 2 million of the estimated 6.7 million people who could benefit from hearing aids in the UK actually use them (RNID, 2024).
• Noise-induced hearing loss remains a leading occupational health concern, with the Health and Safety Executive reporting thousands of new claims annually.

These figures underline the importance of regular hearing checks. A standard hearing test is the gateway to identifying hearing loss before it begins to erode communication, relationships, and quality of life.

Age-Related Hearing Loss — Why Regular Testing Matters

Age-related hearing loss (presbycusis) is the most common cause of hearing difficulty in adults. It develops gradually — often so slowly that people do not notice the change until it has become significant. The earliest sign is usually difficulty following conversations in background noise, even when hearing seems fine in quiet settings. Over time, higher-pitched sounds such as birdsong, doorbells, and consonant sounds in speech (s, t, f, th) become harder to detect.

The British Society of Audiology recommends that adults have a hearing test every three years from the age of 55 onwards, or sooner if they notice any signs of hearing loss. Regular monitoring creates a baseline audiogram against which future results can be compared, making even small changes easy to detect. Early identification means early intervention — and modern hearing aids are discreet, effective, and increasingly packed with features like Bluetooth streaming and rechargeable batteries.

Growing evidence also links untreated hearing loss to wider health risks. A landmark 2023 study published in The Lancet found that hearing aid use was associated with a 48% reduction in cognitive decline among at-risk older adults. The NICE guideline on hearing loss in adults (NG98) emphasises the importance of early assessment and intervention, particularly given the association between hearing loss, social isolation, depression, and dementia.

NHS vs Private Hearing Tests — Your Options

In the UK, you have two main pathways to a standard hearing test, each with its own advantages:

NHS Hearing Tests

An NHS hearing test is available free of charge to everyone in the UK. The typical route begins with a visit to your GP, who will examine your ears and, if appropriate, refer you to the local NHS audiology department. In some parts of England, direct referral pathways now allow you to book an audiology appointment without seeing your GP first — check with your local NHS trust. NHS audiologists are fully qualified and registered with the Health and Care Professions Council (HCPC), and if hearing loss is found, NHS hearing aids are provided completely free, along with batteries, repairs, and lifelong aftercare.

The main consideration is waiting times, which vary from a few weeks to several months depending on demand in your area. For a detailed breakdown, see our NHS vs private hearing test comparison.

Private Hearing Tests

Private hearing tests are widely available on the high street from audiologists and hearing aid dispensers. They typically cost between £30 and £60, though many providers — including Boots Hearingcare, Specsavers Audiology, and Hidden Hearing — offer free initial hearing assessments, particularly if you are considering hearing aids. No GP referral is needed, and appointments can usually be booked within days.

Private providers offer a wider choice of hearing aid styles, brands, and technology levels than the NHS, including invisible-in-canal models, Bluetooth-enabled devices, and rechargeable options. However, private hearing aids are significantly more expensive, typically ranging from £500 to £3,500 per ear.

What Your Results Mean — and What Happens Next

After completing the audiometry, your audiologist will explain your audiogram in detail. If your hearing falls within the normal range (0–20 dB HL across all frequencies), no treatment is needed, though you may be advised to return for monitoring in a few years, particularly if you are over 55 or have risk factors such as noise exposure.

If hearing loss is detected, the next steps depend on the type and degree:

• Mild hearing loss may be monitored with regular follow-up, or hearing aids may be recommended if it is affecting your daily life.
• Moderate to severe hearing loss typically benefits from hearing aids — available free on the NHS or privately with a wider choice of technology.
• Conductive hearing loss may be treatable with ear wax removal, medication, or surgery, and an onward referral to ENT (ear, nose, and throat) may be recommended.
• Sudden or rapidly progressive hearing loss requires urgent medical assessment — if you experience this, contact your GP or attend A&E immediately.

If tinnitus (ringing or buzzing in the ears) is present alongside hearing loss, a specialist tinnitus assessment may be recommended. Your audiologist will discuss all options and help you choose the path that best suits your needs, lifestyle, and budget.

Why Early Detection Matters

The evidence for early hearing intervention is compelling and growing. Untreated hearing loss does not simply mean missing a few words — it cascades into wider health and wellbeing consequences:

• Communication breakdown: Struggling to follow conversations leads to fatigue, frustration, and withdrawal from social situations.
• Social isolation and depression: The RNID reports that people with untreated hearing loss are significantly more likely to experience loneliness and mental health difficulties.
• Cognitive decline: Multiple large-scale studies, including research led by Johns Hopkins University and the UK Biobank, have identified hearing loss as one of the largest modifiable risk factors for dementia.
• Workplace impact: Hearing difficulty in meetings, phone calls, and open-plan offices can affect performance, confidence, and career progression.
• Safety risks: Missing alarms, doorbells, traffic sounds, and warning signals increases the risk of accidents.

The good news is that a standard hearing test takes less than an hour, is widely available, and — if hearing loss is found — opens the door to effective treatment that can transform daily life. The sooner hearing loss is identified, the sooner the brain can adapt to amplification, and the better the long-term outcome.

How to Book a Standard Hearing Test

Booking a hearing test in the UK is straightforward. You have several options:

• NHS route: Visit your GP, explain your hearing concerns, and ask for a referral to NHS audiology. Some areas offer self-referral directly to audiology without needing to see your GP first.
• Private route: Book directly with a high-street audiologist or hearing care provider — no referral needed. Most offer online booking and can see you within days.
• Online screening first: Not sure if you need a test? Try a free online hearing test from a reputable provider like the RNID to get an initial indication — but always follow up with a clinical assessment for a definitive result.
