👂 Sensorineural Hearing Loss (SNHL) – Causes, Degrees, Symptoms & Early Identification
🌟 What is Sensorineural Hearing Loss?
Sensorineural hearing loss (SNHL) is the most common type of permanent hearing loss, caused by damage to the inner ear (cochlea) or the auditory nerve. Unlike conductive hearing loss, SNHL cannot be corrected by surgery or medication, but with early diagnosis and advanced technology, patients can regain communication confidence.

⚠️ Causes of Sensorineural Hearing Loss
SNHL can occur at birth, develop gradually, or appear suddenly. Common causes include:
-
Age-related changes (Presbycusis) – gradual decline after age 50.
-
Noise exposure – loud music, traffic, machinery, or sudden blasts.
-
Genetic factors – inherited hearing loss syndromes.
-
Infections & illnesses – meningitis, measles, diabetes, Ménière’s disease.
-
Ototoxic medications – certain antibiotics, chemotherapy drugs.
-
Tumors – acoustic neuroma affecting the auditory nerve.
-
Head trauma – injury to the inner ear or nerve pathways.
📊 Degrees of Sensorineural Hearing Loss & Detailed Symptoms
🔹 Mild Hearing Loss (26–40 dB HL
Symptoms:
-
Difficulty hearing soft speech or whispers.
-
Trouble following conversations in noisy environments (restaurants, traffic).
-
Children may miss subtle speech sounds like “s” or “th”, leading to unclear pronunciation.
-
Impact: Often unnoticed by adults, but in children it can delay speech and language development.
-
Treatment Options: Hearing Aids (IIC, CIC, RIC, BTE), PAPs

🔹 Profound Hearing Loss (>90 dB HL)
Symptoms:
-
No speech perception at all.
-
Only vibrations or extremely loud sounds are detected.
-
Children may remain non‑verbal without early intervention.
-
Impact: Communication depends on cochlear implants, vibrotactile aids, or sign language.
-
Treatment Options: Cochlear Implants, Vibrotactile aids, Sign Language
