Standard Hearing Loss Grading System
Grade | Threshold (dB) | Description | Hearing Aid Need |
Grade 0 (Normal) | 0-25 dB | No functional limitation | None |
Grade 1 (Slight) | 26-40 dB | Difficulty hearing soft speech | May benefit |
Grade 2 (Moderate) | 41-60 dB | Difficulty with normal speech | Recommended |
Grade 3 (Severe) | 61-80 dB | Only loud speech audible | Essential |
Grade 4 (Profound) | 81+ dB | Cannot hear without amplification | Essential / cochlear implant evaluation |
How Grading Is Determined
Your hearing loss grade is calculated from your Pure Tone Average (PTA) — the average hearing threshold at 500 Hz, 1000 Hz, 2000 Hz, and 4000 Hz. This single number summarizes your overall hearing ability. Read more: Hearing Loss and Diabetes: The Connection Explained
Different Grading Systems
Different organizations use slightly different scales:
WHO classification: Slight, Mild, Moderate, Severe, Profound
ASHA (American): Normal, Slight, Mild, Moderate, Moderately Severe, Severe, Profound
ISO: Similar to WHO but with numerical thresholds
At Professional Hearing Solutions, we use internationally recognized standards for consistent classification
Why Grading Matters
Determines hearing aid power level needed
Guides model selection and feature requirements
Helps track progression over time (comparing grades between tests)
Required for disability documentation in some contexts
Helps set realistic expectations for hearing aid outcomes
How Hearing Loss Affects Daily Life
Hearing loss impacts more than just the ability to hear sounds. It affects communication, relationships, work performance, mental health, and overall quality of life. In Pakistan, where family gatherings, busy markets, and social interactions are central to daily life, hearing loss can be especially isolating.
Common Causes of Hearing Loss in Pakistan
Cause | Type of Hearing Loss | Preventable? | Common in Pakistan? |
Aging (Presbycusis) | Sensorineural | Not fully — manageable with hearing aids | Very common (60+ age group) |
Noise Exposure | Sensorineural | Yes — use hearing protection | Very common (traffic, factories) |
Ear Infections (Otitis Media) | Conductive | Yes — treat infections early | Common in children |
Genetic Factors | Sensorineural or Mixed | No — but early detection helps | Moderate |
Ototoxic Medications | Sensorineural | Yes — discuss with doctor | Moderate |
Head Trauma | Conductive or Mixed | Yes — wear safety equipment | Less common |
Earwax Blockage | Conductive | Yes — professional ear cleaning | Very common |
Signs You Should Get a Hearing Test
Frequently asking others to repeat themselves, especially in group conversations
Turning up the TV or phone volume higher than others find comfortable
Difficulty understanding speech in noisy environments like restaurants or family gatherings
Feeling that people are mumbling or speaking too softly
Avoiding social situations because of difficulty hearing
Ringing, buzzing, or hissing sounds in your ears (tinnitus)
Difficulty hearing doorbells, phone ringtones, or car horns
Treatment Options Available in Pakistan
Treatment | Best For | Available at PHS | Effectiveness |
Hearing Aids | Most hearing loss types | Yes — full Signia range | Highly effective |
Ear Wax Removal | Conductive loss from wax | Yes | Immediate improvement |
Medical Treatment | Ear infections, conditions | Referral provided | Depends on condition |
Surgical Options | Specific conductive cases | Referral to ENT | Case-dependent |
Tinnitus Management | Ringing/buzzing in ears | Yes — Signia notch therapy | Significant relief |
Do Not Ignore Hearing Loss
Research shows that untreated hearing loss is linked to cognitive decline, dementia, depression, social isolation, and increased fall risk. The longer hearing loss goes untreated, the harder it becomes for the brain to process speech. Early intervention with hearing aids preserves brain health and keeps you connected to the people and world around you.
