There are two main kinds of hearing loss:
Sensorineural hearing loss or SNHL is a condition characterized by issues with the sensory nerves in the inner ear.
Conductive hearing loss is another common form of hearing loss, which is due to the inability to conduct sound waves along the route of the outer ear, eardrum, or middle ear.
When these two forms of hearing loss occur simultaneously, it is known as mixed hearing loss. Sensorineural hearing loss is the most common form of hearing loss, and occurs in almost a quarter of the population.
