What is the primary cause of conductive hearing loss?

• A. Damage to the cochlea
• B. Problems conducting sound through the outer or middle ear
• C. Neurological disorders
• D. Age-related changes in the cochlea

Answer: (B)

The primary cause of conductive hearing loss is problems conducting sound through the outer or middle ear. Conductive hearing loss occurs when there are barriers in the transmission of sound waves to the inner ear, which can happen due to a variety of issues in the conductive pathway. These issues may include earwax buildup, fluid in the middle ear, infections, perforations in the eardrum, or malformations of the outer or middle ear structures. Since this type of hearing loss is related to the mechanical aspects of sound transmission rather than neurological or sensorineural problems, it is characterized by a decrease in sound intensity and can often be treated effectively by medical or surgical interventions. This understanding highlights the importance of recognizing the specific areas of the auditory system that are affected in conductive hearing loss, distinguishing it from other types of hearing loss that involve the cochlea or auditory pathways beyond the middle ear.
