The number of hearing impaired individuals has steadily increased over the past few decades. Conductive hearing loss is often temporary and may range from mild to severe. Audioscopy testing. Conductive hearing loss refers to issues with transferring sound waves due to a blockage or other impediment located between the outer and the inner ear. Conductive hearing loss occurs when something occurs that impedes the passage of sound from the external ear to the sensory cells located in the inner ear. It can occur in one or both ears. Some types of conductive hearing loss can be corrected with hearing aids. Majority of the people suffer from Sensorineural Hearing Loss.
