In the context of audiology, how is 'conductive hearing loss' best defined?

Conductive hearing loss is characterized by a problem in the outer or middle ear that prevents sound from effectively reaching the inner ear. This type of hearing loss typically occurs due to a physical blockage or obstruction, which can result from various factors such as earwax buildup, fluid in the middle ear, perforated eardrums, or issues with the ossicles. The essence of conductive hearing loss lies in its mechanical nature, where the pathway for sound waves is disrupted, leading to a decrease in the volume of sounds that can be heard.

Understanding this definition is crucial because it distinguishes conductive hearing loss from other types, such as sensorineural hearing loss, which is the result of damage to the inner ear or auditory nerve. It also clarifies the nature of potential interventions, which may involve medical treatments, surgical procedures, or the use of hearing aids designed to enhance the conduction of sound. This distinction plays an important role in diagnosis and management in audiology practices.
