There are different types of hearing loss, depending on where the problem happens in the ear or hearing pathway. Each type may be caused by different things. Hearing loss happens when there's a problem with:
Conductive hearing loss happens when sound cannot travel well through the outer or middle ear. This may be caused by:
Sensorineural hearing loss happens when the inner ear (cochlea) or the hearing nerve is damaged. Sensorineural hearing loss is usually permanent. It can be caused by:
Asymmetrical hearing is hearing loss in one ear. It happens when there is a problem in the inner ear or the nerve that sends sound to the brain. This kind of hearing loss can happen for a range of reasons, such as:
Mixed hearing loss is when someone has both conductive and sensorineural hearing loss at the same time.
Neural hearing loss is caused by problems in the hearing nerve. It can be due to conditions, such as an acoustic neuroma (a type of tumour) or damage from infections.
Central hearing loss happens when the brain has trouble processing sounds. It can be caused by problems in parts of the brain, such as a stroke or multiple sclerosis. A type of central hearing problem in school-aged children is called auditory processing disorder (APD).

Support and treatment can make a big difference and help improve hearing and communication. Learning sign language, how to read lips or using visual alerts can also be useful.
Untreated hearing loss can lead to more than just trouble hearing. It may lead to:
