Hearing loss is not the same for everyone. The location of the problem within the hearing system determines whether hearing loss is conductive, sensorineural or mixed. Identifying the type is an important part of choosing appropriate hearing care.
The type of hearing loss describes where the difficulty occurs within the hearing system. Conductive hearing loss involves the outer or middle ear, while sensorineural hearing loss involves the inner ear or auditory nerve. When both are present together, the condition is described as mixed hearing loss.
Different parts of the hearing system may be affected.
Hearing sensitivity may be reduced by different amounts.
Some losses can affect clarity as well as loudness.
Hearing loss may be unilateral or bilateral.
Hearing loss can range from mild to profound.
It may occur suddenly or develop gradually.
Hearing levels may remain stable or change over time.
Management depends on the type, cause and degree.
Occurs when sound cannot travel efficiently through the outer ear canal, eardrum or middle-ear structures toward the inner ear.
Results from dysfunction or damage involving the sensory structures of the cochlea or the auditory nerve.
Occurs when conductive hearing loss and sensorineural hearing loss are both present in the same ear.
These involve difficulties in how auditory information is processed by the central auditory nervous system and are distinct from the three basic peripheral hearing-loss types.
Discuss symptoms, onset and listening difficulties.
Check the ear canal and visible ear structures.
Measure hearing through the complete hearing pathway.
Helps separate conductive from inner-ear involvement.
Middle-ear or other tests may be added when required.
Findings guide suitable follow-up and hearing care.
Book a professional hearing assessment to identify your hearing levels, hearing-loss pattern and the next appropriate step for your hearing care.
