Conductive vs sensorineural hearing loss

Conductive hearing loss is for the most part treatable and therefore temporary. In many cases, something is plugging the ear canal, which prevents you from hearing well. As with sensorineural hearing loss there are many causes of conductive hearing loss like Ear wax and other fluid buildups.

  1. Conductive vs Sensorineural Hearing Loss Source - Hearing solutions

  2. Conductive Hearing Loss A conductive hearing loss happens when sounds cannot get through the outer and middle ear. It may be hard to hear soft sounds. The main cause of conductive hearing loss is any kind of blockage in the outer ear. Almost there are many objects blocking the ear canal which fails sound signals to reach the nerve center.

  3. Common Causes ● ● ● ● ● ● ● ● ● ● Foreign bodies in the external ear Allergies Otitis externa Tumors Abnormal growth of the bone near or in the middle ear Ear infections and head colds Perforated eardrum Exostosis An unequal pressure in the middle and the external ear Poor Eustachian tube function.

  4. Sensorineural Hearing Loss Sensorineural hearing loss is a type of hearing loss in which the root cause lies in the inner ear or sensory organ. It is also called Nerve Deafness.It results from damaging of nerve or inner ear. Usually, it occurs in the cochlea or anywhere leading to the brain.If the sensory cells are destroyed in the cochlea then sound waves can’t reach to the brain.

  5. Common Causes ● ● ● ● ● ● ● ● ● Genetics Loud Noise Ageing Head trauma Meniere’s Disease Disease and Infections Tumors Medication Otosclerosis

  6. Conductive vs Sensorineural Hearing Loss Differences Conductive Hearing loss Sensorineural Hearing loss 1. 2. 3. Short Duration hearing loss It can be treated Usually mild and moderate hearing deficiency Rinne test is negative Any kind of blockage in outer ear preventing conduction of sound into the inner ear. Absolute bone conduction is normal 1. 2. Permanent hearing loss Cannot be treated by managed by hearing aids. Absence or damage of sensory hair cells in the middle ear Rinne test is positive Can be mild, moderate, profound and severe. Absolute bone conduction 3. 4. 5. 4. 5. 6. 6.

  7. The measurement of Hearing deficiency 20-50 dB reduction at 4000 Hz Mild Clear sound with slight noise in the background 51-70 dB reduction at 4000 Hz Moderate Low-frequency sound with increased background noise 71-90 dB reduction at 4000 Hz Severe The Hearing is hard with low sound and loud noise 90+ dB reduction at 4000 Hz Profound Murmuring sound with louder noise. Hearing is harder
