Noticing that conversations seem muffled, that you’re constantly asking people to repeat themselves, or that you struggle to follow dialogue in noisy cafés can be unsettling. If you’ve found yourself wondering “why can’t I hear properly?” you’re far from alone, and more importantly, you’re asking the right question.
Hearing loss is common in Australia, yet many people wait years before seeking help. Understanding what might be causing your hearing challenges and knowing when to take action can make a significant difference to your quality of life, relationships, and even your cognitive health.
Common Causes of Hearing Difficulties
Hearing loss rarely happens overnight. More often, it develops gradually, making it difficult to pinpoint exactly when it started or what might be causing it. The reasons behind hearing difficulties are surprisingly varied, ranging from temporary and treatable conditions to permanent changes that require ongoing management.
Conductive hearing loss occurs when sound cannot efficiently travel through the outer or middle ear. This type of loss is often temporary and medically treatable. Common causes include earwax buildup (cerumen impaction), middle ear infections (otitis media), fluid accumulation behind the eardrum, or problems with the tiny bones in the middle ear. People with conductive hearing loss often describe sounds as muffled or quieter than usual, and they may notice their own voice sounds different.
Sensorineural hearing loss involves damage to the inner ear (cochlea) or the auditory nerve pathways. This is the most common type of permanent hearing loss and typically develops due to ageing (presbycusis), noise exposure, certain medications (ototoxic drugs), genetic factors, or illnesses such as viral infections. Unlike conductive loss, sensorineural hearing loss affects not just volume but clarity: people often report they can hear that someone is speaking but struggle to understand the words, particularly in background noise.
Mixed hearing loss combines elements of both conductive and sensorineural loss, whilst auditory processing difficulties involve problems with how the brain interprets sound rather than with the ear structures themselves.
Beyond these clinical categories, several factors can contribute to temporary or fluctuating hearing difficulties. Upper respiratory infections, allergies causing eustachian tube dysfunction, sudden changes in air pressure, and even certain medications can all affect hearing. Age-related changes affect not just the ears but the entire auditory system, including the cognitive processing of speech.
Why Hearing Difficulties Feel Worse in Noise
One of the most common complaints audiologists hear is this: “I can hear fine in quiet, but I can’t understand anything in restaurants or group settings.” This experience is remarkably common and points to the sophisticated challenges our auditory system faces.
Understanding speech in noise requires more than just detecting sound: it demands that your auditory system separate relevant speech from irrelevant background noise, fill in missing information, and process language quickly enough to follow conversation. When any part of the auditory pathway is compromised, even mildly, this complex task becomes significantly harder.
Sensorineural hearing loss often affects high-frequency sounds first: precisely the frequencies that carry consonants like ‘s’, ‘f’, and ‘th’. These consonants provide the clarity and distinction between words. Without them, “fish” and “wish” sound identical, and following conversation becomes exhausting as your brain works overtime to fill in the gaps. This cognitive load explains why people with untreated hearing loss often feel mentally fatigued after social events.
The Diagnostic Process: What Happens During a Comprehensive Hearing Assessment
If you’re concerned about your hearing, understanding what happens during a professional assessment can help ease any apprehension. A thorough audiological evaluation goes well beyond simply testing whether you can hear beeps.
A comprehensive appointment at a quality audiology clinic typically begins with a detailed case history. Your audiologist will ask about the onset and nature of your hearing difficulties, exposure to loud noise, relevant medical history, medications, and family history of hearing loss. This conversation provides crucial context that shapes the rest of the assessment.
Pure tone audiometry forms the foundation of most hearing tests. You’ll wear headphones and respond when you hear tones at different pitches and volumes. This test maps your hearing sensitivity across the frequency range important for speech and daily listening. Results are plotted on an audiogram: a graph that shows your hearing thresholds at each frequency.
Speech testing assesses how well you understand words, both in quiet and in background noise. Speech-in-noise testing is particularly valuable because it often reveals difficulties that pure tone testing might miss, especially in cases of early hearing loss or auditory processing challenges.
Tympanometry evaluates middle ear function by measuring how your eardrum responds to changes in air pressure. This quick, painless test can identify fluid, eardrum perforations, eustachian tube dysfunction, or problems with the ossicles (tiny bones in the middle ear). It’s particularly useful for identifying middle ear problems that cause conductive hearing loss.
Otoscopy, visual examination of the ear canal and eardrum, allows the audiologist to identify wax buildup, infections, structural abnormalities, or other issues requiring medical attention.
For patients being fitted with hearing aids, Real Ear Measurement (REM) represents the gold standard for verification. REM involves placing a tiny microphone in your ear canal whilst wearing the hearing aid, measuring the actual sound levels delivered to your eardrum. This objective verification ensures the hearing aid is providing appropriate amplification for your specific hearing loss and ear canal acoustics, rather than relying on manufacturer default settings. Studies comparing verified and unverified fittings have generally found better outcomes when REM is used.
Red Flags: When to Seek Urgent Assessment
Whilst gradual hearing changes warrant attention, certain symptoms require prompt medical evaluation:
- Sudden hearing loss (developing over hours or days) in one or both ears
- Hearing loss accompanied by dizziness, vertigo, or severe balance problems
- Hearing loss with significant pain, drainage, or fever
- Unilateral tinnitus (ringing in only one ear)
- Hearing loss following head trauma
- Pulsatile tinnitus (hearing your heartbeat in your ear)
These symptoms may indicate conditions requiring medical intervention, and early treatment often improves outcomes significantly. If you experience any of these, contact your GP or an audiologist promptly for appropriate referral. Sudden hearing loss in particular needs urgent medical attention.
Practical Steps: What You Can Do Now
If you suspect you have hearing difficulties, taking action sooner rather than later offers several advantages. The Lancet Commission on dementia prevention identifies hearing loss as one of the potentially modifiable risk factors for dementia. Researchers are still working out how much treating it reduces that risk, but addressing hearing loss early helps social engagement and quality of life.
Step one is to book a comprehensive hearing assessment with a qualified audiologist. In Australia, audiologists complete a university master’s degree or higher, and many are accredited members of a professional body such as Audiology Australia. Look for clinics that use Real Ear Measurement for hearing aid fittings, offer a range of manufacturers (brand-agnostic approach), and clearly explain their fees and services.
Before your appointment, note specific situations where you struggle to hear. Do you have difficulty with the television? Phone conversations? Group gatherings? This information helps your audiologist understand your real-world challenges.
During the assessment, don’t hesitate to ask questions. A good audiologist will explain your test results clearly, discuss whether any medical referral is needed, and outline your options without pressure. If hearing aids are recommended, ask about the verification process, trial periods, and follow-up care. Comprehensive aftercare, including programming adjustments, counselling, and communication strategy training, is essential for successful outcomes.
If hearing aids are appropriate, understand that adjustment takes time. Modern hearing aids are sophisticated devices, but they cannot restore hearing to “normal.” Realistic expectations, combined with consistent use and proper follow-up, lead to the best results. Plan for several follow-up appointments during the initial months as your audiologist fine-tunes the programming and you adapt to amplified sound.
The Limits and Realities of Hearing Solutions
It’s important to approach hearing solutions with realistic expectations. Hearing aids can provide significant benefit, improving speech understanding, reducing listening effort, and enhancing quality of life. However, they work best when properly fitted, regularly maintained, and used consistently. The most advanced technology cannot overcome inadequate fitting or lack of verification through methods like Real Ear Measurement.
Teleaudiology has expanded access to hearing care, particularly for remote communities, but it has limitations. Comprehensive diagnostic testing, Real Ear Measurement, and complex problem-solving typically require in-person appointments. Similarly, over-the-counter or online hearing devices may help some people with mild hearing loss, but they lack the personalisation and professional support that significantly impacts long-term success.
Moving Forward
Asking “why can’t I hear properly?” is the first step toward better hearing health. Whether your difficulties stem from treatable conditions like earwax or more permanent changes requiring hearing aids, understanding the cause and accessing appropriate care makes a meaningful difference.
Quality hearing care involves thorough assessment, transparent communication about your options, proper verification of any devices fitted, and ongoing support. At The Audiology Place in Epping and Forestville, we prioritise evidence-based practice, independence from manufacturers and thorough follow-up care.
If you’re experiencing hearing difficulties, don’t wait. The sooner you seek assessment, the sooner you can take control of your hearing health and maintain the connections to people and activities that matter most.
