Hearing Loss · A Complete Guide
Hearing loss, explained clearly — types, causes, signs, and what actually helps
Hearing loss is common, gradual, and easy to miss in yourself. This guide walks through the degrees and types of hearing loss, what usually causes it, the early signs to watch for, and the treatment options available today — including when hearing loss can be reversed and when it's better managed with hearing aids.

Understanding The Basics
What is hearing loss, and how is it measured?
Hearing is measured in decibels (dB) — how loud a sound needs to be before you can hear it. Normal hearing means you can detect sounds down to about 20 dB. Anything above that threshold is classified into a "degree" of hearing loss. Explore the scale below to see what each degree can sound like day to day.

Degrees are based on the standard clinical dB HL classification and describe the better-hearing ear.
Three Main Types
Conductive, sensorineural, or mixed?
Where the problem occurs along your hearing pathway determines the type of hearing loss — and that, in turn, shapes how it's treated.
Conductive Hearing Loss
Sound is blocked from reaching the inner ear, often due to earwax buildup, fluid, infection, or a damaged eardrum. Frequently temporary and treatable with medical care.
Sensorineural Hearing Loss
Damage to the tiny hair cells of the inner ear or the hearing nerve itself — the most common type in adults, usually from aging or noise exposure. Typically permanent, and well managed with hearing aids.
Mixed Hearing Loss
A combination of conductive and sensorineural causes happening at once — for example, age-related inner ear damage alongside a middle ear infection.
Root Causes
What commonly causes hearing loss?
-
Aging (Presbycusis)
A gradual, natural decline in inner-ear function that usually becomes noticeable from the mid-60s onward.
-
Prolonged noise exposure
Loud workplaces, machinery, traffic, and personal audio devices can gradually damage inner-ear hair cells over time.
-
Genetics & family history
Some forms of hearing loss run in families or are present from birth due to inherited conditions.
-
Ear infections & fluid buildup
Chronic or repeated middle-ear infections, common in childhood, can affect hearing temporarily or, in some cases, longer term.
-
Certain medications
Some drugs are ototoxic and can affect hearing as a side effect, particularly at high doses or with prolonged use.
-
Head or ear injury
Trauma to the head or ear, including sudden pressure changes or a ruptured eardrum, can cause temporary or permanent hearing loss.
Early Signs

Tick anything that feels familiar. This isn't a diagnosis — it's a quick way to see whether it's worth booking a proper hearing test.
What Actually Helps
Treatment and management options
The right option depends on the type and degree of your hearing loss — an audiologist will guide you through this after a proper test.
| Option | Best for | What to know |
|---|---|---|
| Medical treatment | Conductive causes (infection, fluid, wax) | Often resolves the issue directly — sometimes hearing returns fully |
| Hearing aids | Mild to profound sensorineural loss | Available in BTE, RIE, ITE, ITC, IIC and CIC styles |
| Assistive listening devices | Specific situations like TV, phone, or lectures | Often used alongside hearing aids, not instead of them |
| Communication strategies | Everyone with hearing loss | Facing the speaker, reducing background noise, and asking for repetition all help |
| Cochlear implants | Severe to profound loss with limited hearing aid benefit | A surgical option assessed and referred by a specialist |
Looking After Your Hearing
Simple ways to help protect your hearing
- Use ear protection around loud machinery, concerts, or traffic
- Keep headphone volume moderate, especially for long listening sessions
- Give your ears quiet breaks after loud events
- Get chronic ear infections or persistent fluid checked promptly
- Book a baseline hearing test, then re-test every few years after 50
Why early testing matters
Hearing loss usually develops gradually, so it's easy to adapt without noticing how much you're missing. Left unaddressed, it's been linked to social withdrawal and greater listening fatigue — catching it early simply makes it easier to manage well.

Common Questions
Hearing loss: frequently asked questions
Normal hearing means you can detect sounds down to about 20 decibels (dB) in both ears. Hearing loss is when your threshold is higher than that, and it's described in degrees — mild, moderate, moderately severe, severe, or profound — based on how loud a sound needs to be before you can hear it.
The three main types are conductive hearing loss (a problem in the outer or middle ear that blocks sound), sensorineural hearing loss (damage to the inner ear or hearing nerve), and mixed hearing loss, which is a combination of both.
It depends on the cause. Conductive hearing loss from earwax buildup, fluid, or infection is often treatable and can improve once the underlying cause is addressed. Sensorineural hearing loss, the most common type in adults, is usually permanent, but it can be effectively managed with hearing aids or other devices.
Common early signs include asking people to repeat themselves, struggling to follow conversations in noisy places, turning the TV up louder than others prefer, feeling like people are mumbling, and avoiding social situations because listening feels tiring.
An audiologist diagnoses hearing loss with a hearing test called an audiogram, which measures the quietest sounds you can hear at different pitches in each ear. This maps out the type and degree of any hearing loss so treatment can be tailored to you.
Age-related hearing loss (presbycusis) typically becomes noticeable from the mid-60s onward, though it can begin earlier depending on noise exposure, genetics, and overall health. Hearing loss can also occur at any age, including from birth, due to other causes.
Adults with no risk factors are generally advised to have a baseline hearing test and then check again every few years after age 50, or sooner if you notice any changes. If you're regularly exposed to loud noise or have a family history of hearing loss, more frequent checks are worthwhile.
