Causes in the outer ear
Typical problems with the outer ear (A) include ear wax plugs and infections of the auditory canal. Usually, addressing these problems is very easy. But it is important to act quickly in order to avoid hearing damage.
Causes in the middle ear
Inflammation, fluid behind the eardrum, perforations of the eardrum and otosclerosis (a stiffening of the bones in the middle ear) are the most common problems to interfere with middle ear (B) function. Most outer and middle ear problems can be addressed effectively with medication or surgery. If this is not possible, permanent hearing loss can be compensated with a hearing aid in most cases.
Causes in the inner ear
The majority of hearing issues concern the inner ear (C). The most common cause is the natural aging process. But loud noise, taking some types of medication, or skull fractures can also have a negative influence on a person's hearing ability. These influences damage the fine hair cells and affect the transmission of signals to the auditory nerves. Usually, inner ear hearing loss cannot be addressed medically. However, this type of hearing loss can be corrected with a hearing aid in most cases.
