Hearing tests: audiograms, speech, middle-ear measures and screening follow-up
On this page
Hearing assessment examines how sounds are detected and understood, and may investigate different parts of the hearing pathway. Conductive loss involves transmission through the outer or middle ear; sensorineural loss involves the inner ear or hearing nerve. Tests help distinguish these categories.[1]
Methods that examine different responses
| Test or quantity | What it examines | Interpretation boundary |
|---|---|---|
| Pure-tone audiometry | The softest tones detected at tested pitches | The result is plotted on an audiogram[2] |
| Speech testing | Detection and understanding of words or sentences | Communication involves more than tone detection[3] |
| Tympanometry | Eardrum and middle-ear response as pressure changes | The graph describes middle-ear mechanics[3] |
| OAE and ABR | Inner-ear emissions or auditory-pathway electrical responses | These support assessment when a spoken response is impractical[4] |
Pitch and loudness are different axes
Pure-tone testing presents sounds through earphones. The person signals when a tone is heard. An audiogram records the softest detected sounds at the tested frequencies. These thresholds describe a pattern across pitches, rather than a universal hearing percentage. These behavioral responses depend on understanding and performing the task.[2]
Recognizing speech is a related, separate task
Speech testing uses words or sentences at different levels. The person repeats them or responds in another suitable way, such as pointing to pictures. Testing can examine understanding in noise as well as quieter conditions. Audiologists may use it alongside pure-tone testing, because detecting a tone and following a conversation do not require exactly the same response. Name the tested listening condition before comparing speech scores from different reports.[2]
Tympanometry does not ask which words were heard
ASHA describes tympanometry as a measurement of middle-ear function. A probe changes pressure in the ear canal and records the system’s response on a tympanogram. Patterns can help investigate fluid, eardrum problems or other middle-ear conditions. This adds mechanical information, rather than duplicating a word-recognition score. Interpretation belongs with the ear examination and other findings, rather than treating one graph shape as a complete diagnosis.[3]
Age and ability to respond change the method
Babies cannot perform an adult button-press task in the same way. Otoacoustic emissions examine a response from the inner ear, while auditory brainstem response measures electrical responses to sound using electrodes. Older children may use behavioral audiometry, including tones and speech. A complete evaluation can combine methods. Results should therefore be read with the child’s age, cooperation and the actual test, rather than assuming that every hearing screen measures identical information.[4]
Why a test may use headphones and a bone vibrator
Air-conduction tones travel through the outer and middle ear before reaching the inner ear. A bone vibrator sends vibration through the skull toward the inner ear, bypassing much of that transmission route. Comparing the two helps investigate where a hearing problem may arise. An audiogram records thresholds across pitches; the pattern and other examination findings matter together.[8]
Noise can help identify which ear responded
Sound presented to one side can sometimes be heard by the other ear. Audiologists may therefore play masking noise to the non-test ear while measuring the intended ear. This is part of obtaining ear-specific information, not a treatment or an extra score of everyday conversation ability.[9]
Evidence & uncertainty
A comprehensive assessment considers onset, symptoms, prior results and communication difficulties as well as measurements. Trouble understanding speech in noise, a gradual change and a sudden change are different clinical concerns. A simple screening result does not supply the same information as a diagnostic examination. A normal tone audiogram does not settle every speech-in-noise complaint.[3]

Does an audiogram give one percentage of hearing ability?
Selected-source overview · Independent review pending. Read the evidence context.
It records hearing thresholds at tested pitches, rather than a single universal percentage. The pattern across frequencies and the other assessment findings help explain practical difficulty. Speech understanding may require additional testing.[2]

Can tone detection and understanding conversation give different information?
Selected-source overview · Independent review pending. Read the evidence context.
Yes. Speech testing examines words or sentences and may include background noise. Pure tones assess detection at selected pitches. Audiologists can combine the methods to understand hearing and communication more fully.[2]

Is tympanometry another word-recognition score?
Selected-source overview · Independent review pending. Read the evidence context.
No. It measures middle-ear mechanics as pressure changes. It can help investigate problems affecting sound transmission, but it is interpreted alongside other findings. It does not directly report how many spoken words the person understood.[3]

Does a newborn screening referral settle the diagnosis?
Selected-source overview · Independent review pending. Read the evidence context.
No. Prompt pediatric audiology follow-up determines whether a hearing problem exists and clarifies its type and extent. A screening referral is the beginning of that assessment.[5]

Do infants and older children always get the same tests?
Selected-source overview · Independent review pending. Read the evidence context.
No. Age and ability to respond affect the method. Infants may have physiological response tests, while older children may respond to tones and speech. Several examinations can contribute to a complete assessment.[4]

Does uncertain evidence on older-adult screening mean symptoms should be ignored?
Selected-source overview · Independent review pending. Read the evidence context.
No. The USPSTF statement concerns defined asymptomatic adults. People reporting hearing problems or a sudden change are outside that screening population and need appropriate clinical assessment. An insufficient-evidence statement is not proof that investigating a complaint has no value.[6]

Why was a vibrating device placed behind my ear during the hearing test?
Selected-source overview · Independent review pending. Read the evidence context.
It measures bone-conduction hearing, helping compare the route through the outer and middle ear with stimulation reaching the inner ear through skull vibration. The audiologist interprets both patterns together.[8]

Why did I hear noise in the other ear during testing?
Selected-source overview · Independent review pending. Read the evidence context.
It may have been masking noise, used so that the other ear does not supply the response intended for the test ear. Ask the audiologist which ear and measurement were being assessed.[9]

A suspected transmission problem needs complementary information
MedlinePlus distinguishes conductive, sensorineural and mixed hearing loss. Wax, fluid or an eardrum problem can affect transmission, while inner-ear or nerve injury involves a different pathway. Determining the type can change which management options are considered.[1]
A screening referral starts a further assessment
NIDCD advises prompt pediatric audiology follow-up after a newborn screen suggests hearing loss. Further examination determines whether a problem exists and its type and extent.[5]
An apparent air–bone gap needs interpretation
An air–bone gap means air-conduction hearing thresholds are poorer than bone-conduction thresholds at a particular pitch. It can suggest a transmission problem, but an isolated gap is not a diagnosis. A 2026 retrospective study of hearing-aid referrals at one rehabilitation centre found apparent gaps even in ears classified as having sensorineural loss. The result depended on particular earphones, bone vibrators and testing methods; it is a reason to consider measurement artefacts, not to dismiss conductive hearing loss.[10]
Uncertainty about routine screening has a defined population
The USPSTF finds insufficient evidence about the balance of benefits and harms of screening asymptomatic adults aged 50 or older for age-related hearing loss. This is not a recommendation to ignore hearing difficulty. Its scope excludes reported symptoms, sudden loss, conductive or congenital loss and other specified circumstances. Detecting an impairment and showing benefit from a population screening program are different research questions; an evidence gap about the latter does not establish that diagnostic assessment is useless.[6]
A sudden change should not wait for a routine screen
Sudden hearing loss needs immediate medical assessment; do not wait for a routine screening appointment.[7]
