Ear Health: Audiometry and Otoscope Features in Clinics On Cloud

An audiometry test is a hearing screening that presents pure tones at different pitches and volumes through headphones and records the quietest tone a person reports hearing at each pitch, ear by ear. The plotted result is called an audiogram.

The test does not treat anything and does not by itself name a cause. It describes hearing sensitivity at a moment in time, and an audiologist or ENT specialist interprets that description alongside history, examination and further testing.

Clinics On Cloud builds two ear health parameters into its kiosks: audiometry and otoscope ear visualisation. Clinics On Cloud is India’s first CDSCO-licensed Health ATM and Health Kiosk manufacturer, based at Nighoje, Chakan MIDC, Pune, and screens hearing in the same session as vitals, vision, cardiac and point-of-care tests.

Hearing is the parameter people postpone longest. Reduced hearing arrives gradually, is easy to compensate for socially, and rarely hurts. Screening at the workplace or community camp is how that pattern gets interrupted.

The pairing matters. A screening audiogram alone tells you a person heard less. The paired image gives the reviewing clinician immediate context for why that might be, starting with the most ordinary explanation of all, a blocked canal.

• The user puts on calibrated headphones and sits in the quietest available position, since ambient noise is the biggest threat to a screening audiogram.
• Voice and on-screen guidance, available in multiple languages, explain the task: press when you hear a tone, however faint.
• Tones are presented one ear at a time, across a range of frequencies, stepping down in volume to find the quietest level reported at each pitch.
• The kiosk plots an audiogram for each ear and renders it in a colour-coded report delivered by print, SMS, email or WhatsApp.
• The result is stored in a digital health record, so this year’s audiogram sits next to last year’s for the same person.
• Where hearing is flagged, the kiosk offers an integrated telemedicine consultation and a referral to an audiologist or ENT specialist.

Clinics On Cloud states device accuracy of 90 to 95 percent depending on test and device, under correct usage, calibration and patient preparation. For audiometry, correct usage is mostly environment: run the test in the quietest room available, not next to the shop floor, and repeat any test where the person was distracted. The exact frequency set the module presents is a configuration detail, so confirm it with the Clinics On Cloud team against your occupational health protocol before standardising a programme on it.

An otoscope examination is a visual inspection of the ear canal and the eardrum using a lighted instrument, performed on a Clinics On Cloud kiosk with a digital otoscope that captures high-resolution images. The images appear on screen and are saved to the person’s record.

The device captures pictures. It does not read them. What the images enable is a clinician looking at a clear view of an ear canal and tympanic membrane during a teleconsultation, without the person travelling to an ENT clinic first.

Each examination uses a single-use speculum, discarded after one person. The examination is painless and takes under a minute per ear when performed by a trained operator.

The most common practical finding is also the most mundane: an ear canal blocked with wax. That matters for the screening itself, because an obstructed canal can affect a hearing test, and it matters for the person, because the remedy is straightforward once a qualified clinician has looked. Do not attempt to clear an ear canal yourself, and do not put anything into the ear on the basis of a screening image.

A screening audiogram answers how much a person heard. An otoscope image gives the reviewing clinician the first look at why. Run separately, the two produce two appointments. Run together, they produce one usable clinical picture.

This pairing is what makes remote ear review viable. A doctor on a video call cannot look inside an ear. A doctor reviewing a stored, well-lit image of the canal and eardrum alongside an audiogram can judge far better who needs an in-person ENT appointment. The same image-plus-teleconsultation model runs through skin, hair and nail imaging for teledermatology.

• Workers exposed to sustained noise: forging, pressing, weaving, grinding, boiler houses, compressors, generators, drilling and blasting operations.
• Mining workforces, both underground and open-cast.
• Construction, road building and infrastructure crews working with heavy plant.
• Airport ground staff, railway workshop staff and workshop mechanics.
• Musicians, sound engineers, event crews and hospitality staff in high-volume venues.
• School children, since undetected hearing difficulty is easily mistaken for inattention or slow learning.
• Adults reporting the everyday signals: turning the television up, asking people to repeat themselves, struggling to follow conversation in a noisy room, or ringing in the ears.
• Older adults as part of a routine preventive checkup.
• Anyone with ear pain, discharge, blocked-feeling ears or sudden change in hearing, who should see a qualified physician promptly rather than wait for a camp.

A common workplace rule of thumb is that if people have to raise their voices to be understood at arm’s length, the area is worth assessing for noise. Treat that as a prompt to involve your occupational health physician, not as a measurement.

Noise-induced hearing loss is the strongest reason Indian employers buy hearing screening. It develops slowly, it is not reversible, and the worker rarely reports it early, which is precisely the combination that periodic screening exists to address.

Occupational health obligations for Indian factories sit under the Factories Act, 1948 and the applicable state factory rules, with mining workforces overseen by the Directorate General of Mines Safety. Noise exposure limits and periodic medical examination requirements vary by process and jurisdiction, so confirm your specific obligations with your factory medical officer or occupational health physician. No exposure limits or thresholds are stated on this page, because they belong in your statutory compliance document, not in a blog post.

The operational problem employers face is throughput. Sending workers off-site to an audiologist means lost shifts, low turnout and no baseline for most of the workforce. A kiosk at the plant gate reverses that: screening happens during the shift, and every worker gets a dated audiogram that can be compared next year.

Three deployment patterns work in practice:

• Single large plant: a Clinics On Cloud Health Kiosk at the occupational health centre.
• Multiple plants in a region: a Mobile Medical Unit on a periodic circuit.
• Remote mine sites with no infrastructure: the portable Box Clinic, offline with 3 to 4 days of battery backup.

Screen hearing alongside pulmonary function testing and what PEF, FVC and FEV1 measure and far vision, near vision and colour blindness screening, since the same worker in the same visit usually needs all three.

A screening audiogram within the expected pattern indicates that hearing sensitivity looked unremarkable under test conditions on that day. It does not rule out ear disease, and it does not mean noise protection can be relaxed.

A flagged audiogram indicates reduced sensitivity at one or more tested pitches and that an audiologist or ENT specialist should assess you. It does not tell you the cause, the type or the permanence of that change, and a screening device is not the place to learn any of those things. Formal audiometry in a sound-treated booth, with clinical examination, is the next step.

An otoscope image showing something unusual indicates that a clinician should look at it. Nothing more should be read into an image by the person screened, and no ear drops, oils, syringing or cleaning should be attempted on the basis of one.

Sudden hearing loss, ear pain, discharge, dizziness or ringing that starts abruptly needs prompt medical attention rather than a wait for the next screening round. Across the Clinics On Cloud network, 2 lakh+ abnormalities have been detected and routed for early intervention, and the referral is the part that produced the outcome.

Kiosk audiometry is a screening test performed in an ordinary room. Diagnostic audiometry is performed in a sound-treated booth by an audiologist, includes air and bone conduction testing, speech testing and tympanometry, and produces a clinical assessment. These are different things with different purposes.

Clinics On Cloud is not a diagnostic laboratory and does not replace an audiologist or an ENT department. What the kiosk offers is coverage: the whole workforce, the whole school, the whole village, screened and dated, with a referral pathway attached and a record that supports comparison over time.
