What is speech-in-noise testing?
Speech-in-noise testing measures how well you understand speech when there is background noise, such as in a busy restaurant or a crowded room. A standard hearing test is done in quiet, which does not reflect the situations many people find hardest. This test is designed to fill that gap.
During the test you listen to words, numbers or sentences with background noise (often a babble of voices) playing at the same time. As the test goes on, the noise usually becomes harder relative to the speech. You repeat what you hear, and the audiologist works out the listening conditions in which you can understand about half of what is said. This is described as a signal-to-noise ratio — how much louder the speech needs to be than the noise for you to follow it.
The test provides information; it does not treat anything. It is especially useful for people who feel they struggle in noisy places even though a standard hearing test looks normal or near-normal. A result guides what to do next — such as a hearing-aid trial, listening strategies, or further tests — and is read alongside your other hearing results, rather than diagnosing a cause on its own.
One important point: difficulty hearing in noise is common and real, and a normal standard hearing test does not mean the problem is imagined. This test helps put a measure on it.
Types, options & approaches
There may be different ways to do this. The right approach depends on the clinical question and your circumstances.
Standard hearing test vs speech-in-noise testing
| Standard test (in quiet) | Speech-in-noise test | |
|---|---|---|
| Listening condition | Quiet room | With background noise |
| What it reflects | Quietest sounds heard | Real-world busy places |
| Can be normal yet… | you still struggle in noise | this is what it detects |
| Result | Audiogram | Signal-to-noise ratio |
A standard test can look normal while you still find noisy places hard. Speech-in-noise testing is designed to measure exactly that difficulty.
Preparing for your test
- Keep your ears free of anything blocking them; mention earwax, a cold or an ear infection, as these can affect the test.
- Bring your hearing aids if you already wear them, and your glasses if you need them.
- Try to attend when you are rested, as concentration affects how you do in noise.
- Note the situations you find hardest (for example restaurants, meetings, groups), so the result can be discussed against real life.
- Mention if English is not your first language or if you have a strong accent, so the test is chosen and interpreted fairly.
- Bring any previous hearing results to compare.
What happens
You sit in a quiet room and usually wear headphones. The audiologist plays speech — numbers, words or sentences — together with background noise, and asks you to repeat what you hear. You are encouraged to guess even when you are unsure.
As the test continues, the balance between speech and noise is adjusted, often getting harder, to find the listening conditions in which you can understand about half of what is said. The test is comfortable and usually takes only a few minutes, often within a longer hearing appointment.
Results are typically explained on the day, alongside your standard hearing test and any other results, to build a fuller picture of how you hear in everyday situations.
Is this test right for me?
A good consultation should explore whether it's the right choice for you now — including reasons to wait or consider something else.
May not be suitable if…
- Sudden hearing loss needs urgent assessment, not a routine booked test.
- It is not a substitute for a standard hearing test; it adds to it.
- It is the wrong test if you cannot hear or repeat speech at all because of very severe loss.
- It cannot, on its own, diagnose the cause of difficulty hearing in noise.
Delay or rearrange if…
- You have a heavy cold, ear infection or a lot of earwax that could affect the result.
- You are very tired or unwell, which affects concentration in noise.
- You have had recent ear surgery and have been advised to wait.
- There is a sudden change in your hearing that needs urgent review first.
Alternatives to discuss
- Pure tone audiometry and speech testing in quiet for a basic picture.
- A hearing-aid trial with real-world listening as the test.
- Listening strategies and assistive devices without further testing in mild cases.
- Referral for further assessment if a specific cause is suspected.
Before you decide
Use this as a shared-decision checklist. The aim is not just “can this be done?”, but whether it is right for you, now, with the risks and alternatives clearly understood.
What matters most to me?
Think about symptoms, daily life, work, caring responsibilities, sport, fertility, travel, appearance and anxiety — the right choice depends on your priorities, not just the medical facts.
What are all my options?
Ask about waiting, monitoring, medicines, rehabilitation, a smaller or larger procedure, a different test, NHS referral, or a second opinion where that would help.
What would make me pause?
Active infection, pregnancy, unstable medical problems, smoking, medicines that increase bleeding, poor support at home, or feeling pressured are all reasons to slow down and get tailored advice.
What happens if I do nothing today?
For some problems, waiting is safe; for others, delay can make treatment harder. A good consultation should explain the trade-off in plain English.
Benefits
- Measures how well you follow speech in background noise
- Can reveal a real difficulty even when a standard hearing test looks normal
- Reflects the situations many people actually find hardest
- Helps guide hearing-aid decisions and listening strategies
- Quick to do and easy to repeat
- Provides a baseline to compare against in future
Risks & complications
- Mild tiredness or frustration from listening in difficult noise
- A result affected by language, accent or concentration
- Sometimes needing to repeat the test for a reliable result
- A score that needs careful explanation to make sense of
- A result that does not fully match your day-to-day experience
- Difficulty completing the test if hearing loss is significant
- Needing further tests to explain an unexpected result
- Unreliable results because of a problem with cooperation, language or equipment
Speech-in-noise testing is usually not painful and carries essentially no physical risk. Its main limitation is that the score depends on hearing, attention, language and accent, so it is interpreted in context rather than as a fixed number. A result helps explain and guide management of your difficulty in noise; it does not, by itself, diagnose the cause. Ask what your result means for everyday listening and whether hearing aids or strategies would help.
Published figures to discuss
Speech-in-noise testing is non-invasive, so complication rates are not meaningful. What matters is reliability: scores depend on hearing, attention, language and accent, and can vary between sessions and between different tests. There are no robust adverse-event rates to quote, so none are given here. The result is interpreted alongside your other hearing tests and your real-world experience.
| Figure | Reported range | How to interpret it | Source / confidence |
|---|---|---|---|
| Physical harm from the test | None expected | The test uses controlled speech and background noise at safe listening levels. | Guide sourcesClinical context |
| Normal pure-tone test but abnormal speech-in-noise result | Recognised pattern | This can reveal real-world listening difficulty that a standard audiogram misses. | Guide sourcesClinical context |
| Result affected by attention, language or fatigue | Common limitation | Scores should be interpreted with communication goals and other audiology results. | Guide sourcesClinical context |
| Poor result without practical plan | Avoidable | Useful follow-up includes hearing-aid programming, remote microphones, classroom/workplace changes and communication strategies. | Guide sourcesClinical context |
These are literature figures, not a personalised prediction. Your own risks and likely benefits depend on your circumstances, your health, and how your care is carried out and followed up.
What happens afterwards
There is no physical recovery from speech-in-noise testing. You can carry on with your day straight away. What matters afterwards is how the result is explained alongside your other hearing tests and your real-life difficulties.
- Feeling a little tired after concentrating in noise
- No physical after-effects
- Having the result explained alongside your other hearing tests
- Sometimes repeating part of the test for reliability
Aftercare
- Ask what your signal-to-noise result means for everyday listening in plain terms.
- Discuss how the result fits with the situations you find hardest.
- If hearing aids are suggested, ask how they might help in noise specifically, and about their limits.
- Ask about listening strategies and assistive devices that can help in noisy places.
- Keep a copy of your result so future tests can be compared.
- Attend any follow-up or hearing-aid fitting that is arranged.
- Ears free of blockage, with earwax or a cold mentioned if present
- Existing hearing aids and glasses brought along
- Note of the situations you find hardest
- Language or accent factors flagged to the team
- Previous hearing results brought to compare
- Questions written down about hearing aids and strategies
⚠ Get urgent help if…
- Sudden hearing loss, especially in one ear — this should be assessed urgently, separately from a routine test
- New ringing in one ear with hearing loss, which should be reviewed promptly
- Hearing difficulty with dizziness, facial weakness or severe headache — seek prompt medical advice
- Ear pain, discharge or a feeling of fullness that is getting worse
- A sudden, marked worsening in following conversations
Who to contact: your clinician, clinic or test provider first (keep their number to hand). For urgent advice when you can't reach them, call NHS 111. In an emergency, call 999.

Results & realistic expectations
A good result is a clear measure of how much harder you find speech in noise, often expressed as a signal-to-noise ratio. The more the speech needs to stand out above the noise for you to follow it, the more difficulty the test has captured. This can validate a real problem that a standard hearing test in quiet may have missed.
Results have limits. The score depends on hearing, attention, language and accent, so it is interpreted in context and may vary between sessions. It does not, on its own, diagnose the cause of the difficulty, which can involve the inner ear, the hearing nerve or how the brain processes sound. Your audiologist reads it alongside your standard hearing test, your history and your everyday experience.
How well you hear in noise can change over time, so the result reflects how things are now. If your difficulty in noisy places changes, the test may be repeated. It is also useful for checking how much benefit hearing aids or strategies are giving in noise.
Related tests, treatments or support
Speech-in-noise testing is usually done alongside pure tone audiometry, speech audiometry in quiet, and middle-ear tests such as tympanometry, as part of a full hearing assessment. The results together help decide whether hearing aids, listening strategies or further tests are the right next step.
Follow-up & long-term care
The result is usually explained on the day, as part of your overall hearing assessment. If hearing aids or strategies are recommended, the speech-in-noise result helps guide them and may be repeated to check benefit. Further tests or referral are arranged if the result is unclear or unexpected.
Repeat, follow-on and what comes next
- The test may be repeated if results are inconsistent or affected by tiredness or a cold.
- It is useful to repeat when checking benefit from hearing aids or strategies.
- Different speech-in-noise tests can give different scores, so comparisons use the same test where possible.
- Results can change as hearing changes, so testing may be repeated over time.
Ask what happens if the result is unclear or needs repeating, and what is included if further tests or follow-up are needed.
What good aftercare looks like
- A plain-English explanation of your result and what it means for noisy situations.
- Realistic discussion of how much hearing aids and strategies can help in noise.
- Advice on listening strategies and assistive devices.
- A written record and a route to further testing or referral if needed.
What affects the cost
Costs vary a great deal between people and providers, and we don't publish prices. What matters is understanding what drives the cost and making sure your quote is complete. The main things that affect it:
- Whether it is part of a fuller hearing assessment or a standalone test
- The audiologist's time and equipment
- Which test is used (numbers, words or sentences)
- Whether results are linked to hearing-aid fitting and strategies
- Any follow-up appointment to discuss results
- Further tests if results are unclear
- Which tests are included in the appointment
- The audiologist's and facility fees
- Whether a written report and results discussion are included
- Whether hearing-aid assessment is included or separate
- Any follow-up appointment cost
- What happens, and what it costs, if more tests are needed
On the NHS? Speech-in-noise testing is available in some NHS audiology services, and online screening versions are freely available; private testing may be used for speed, convenience or choice of provider.
You're entitled to your total cost in writing — including reports, follow-up and what happens if the result is inconclusive — before you decide.
Consent traps and marketing red flags
These are not small details. They are often where patients lose choice, time to reflect, or realistic expectations.
Consent traps
- Treating the score as a fixed or exact measure rather than one that varies with conditions and the test used.
- Not allowing for language and accent when interpreting the result.
- Implying hearing aids will fully solve difficulty in noise.
- Suggesting the test diagnoses the cause on its own.
Marketing red flags
- Promising hearing aids will eliminate all background noise.
- Using a poor score to push expensive devices without explaining realistic limits.
- Suggesting a single test fully explains your hearing difficulties.
- Implying a normal result means you have no hearing problem at all.
Choosing a specialist safely
- Check the specialist is on the GMC Specialist Register for this area.
- Make sure they work at a CQC-registered service, and look for membership of the relevant Royal College or professional body.
- You're entitled to time to consider and to have your questions answered before you agree — the specialist who looks after you should explain it, not a salesperson.
- Be wary of pressure: time-limited offers or deposits taken before you've had time to think are red flags, not bargains.
- You're entitled to your total cost in writing — including any follow-up — before you decide.
Questions to ask your medical professional
Take this to your consultation. A good specialist will welcome every one of these.
- What does my signal-to-noise result mean for everyday listening?
- Does this explain why I struggle in noisy places despite my hearing test?
- Would hearing aids help in noise, and what are their limits?
- What listening strategies or devices could help me in busy places?
- Could language, accent or tiredness have affected my result today?
- Do I need any further tests to understand the cause?
- Are you on the GMC Specialist Register for this area, and which Royal College or professional body are you a member of?
- Will you be the specialist who carries out my test, and who looks after me afterwards?
- What are the risks for someone like me, and how often do your own patients have a problem or need it repeated or redone?
- What does a realistic result look like — and what can this test not achieve?
- What are my options, including waiting, doing nothing for now, or choosing a different approach?
- Can I have written information, results and aftercare instructions in a format I can use, including any accessibility or communication support I need?
- What is the total cost in writing, including any follow-ups, and how much time do I have to decide?
