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.

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

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
