When we talk about conductive hearing loss, this is probably caused by a middle-ear-to-outer-ear blockage. If we speak simply and directly, conductive hearing loss is something in which sound cannot reach the inner ear. It can be due to ear infections, blockages, and some other types of abnormalities in your structure. This sounds most common in young children; in most cases, conductive hearing loss can be reduced with treatment. Left untreated, symptoms may worsen, causing permanent hearing impairment.
