Sensorineural Hearing Loss

What is Sensorineural Hearing Loss?

Sensorineural Hearing Loss (SNHL) occurs when the delicate structures of the inner ear or the auditory nerve are damaged. This type of hearing loss often makes sounds seem muffled or distorted, especially in noisy environments. Unlike conductive hearing loss, SNHL is usually permanent, but with the right treatment and hearing devices, individuals can significantly improve their quality of life.

Causes of Sensorineural Hearing Loss

Aging (Presbycusis)

Gradual deterioration of the inner ear cells due to aging.

Noise Exposure

Prolonged exposure to loud sounds damages the hair cells in the cochlea.

Genetic Factors

Inherited conditions that impact hearing function.

Symptoms of SNHL

Difficulty understanding conversations, especially in noisy places.

Frequently increasing TV or music volume.

Trouble following group discussions.

Sounds may seem unclear or distorted.

Diagnostic Test

Audiogram & Diagnosis

An audiogram maps the softest sounds you can hear across pitches (typically 250–8,000 Hz). In sensorineural loss, both air and bone conduction thresholds dip together, which helps your clinician confirm the type and degree of hearing loss.

Measures thresholds across frequencies (250–8k Hz)
Compares air vs bone conduction
Classifies degree: mild, moderate, severe, profound

15–20 min Non-invasive Same-day report

Air vs Bone Conduction

SNHL typically shows no significant air–bone gap. If a gap is present, it suggests a conductive or mixed component.

SNHL Pattern

Pure-Tone Testing

Headphones deliver tones; you respond to the faintest sounds heard.

Bone Conduction

A tiny vibrator behind the ear bypasses the middle ear to test the cochlea directly.

Management & Treatment

Hearing Aids – Advanced digital aids improve clarity and speech understanding.

Cochlear Implants – For severe to profound cases where hearing aids are not effective.

Assistive Listening Devices – Tools that help in specific environments like classrooms or meetings.

Lifestyle Adjustments – Protecting ears from noise, regular check-ups, and therapy sessions.

Frequently Asked Questions

Yes, SNHL is typically permanent, but hearing aids and implants can provide effective solutions.

Most cases cannot be cured with medication, but treatment can manage the condition effectively.
