There are several different types of hearing loss, all resulting in varying degrees of actual auditory loss. The two main forms of hearing loss, however, are conductive hearing loss and sensorineural hearing loss.
Conductive hearing loss typically occurs due to a lesion in the external auditory canal or middle ear. This form of hearing loss is usually found in people under the age of 40 and it is typically temporary, as draining the infected middle ear drum will return hearing to normal.
Sensorineural hearing loss is the other main form, and is typically due to a lesion of the auditory division of the 8th cranial nerve or the inner ear. While conductive hearing loss happens to those under the age of 40, sensorineural is most prevalent in those who are middle aged and older. Even so, extended exposure to loud music can lead to sensorineural hearing loss in adolescents.
You should undergo a hearing test if one of the following situations applies to you:
- Children who have frequent ear infections
- When hearing loss lasts more than six weeks
- When fluid in the middle ear persists for more than three months
There are several different medical devices that are able to test hearing, including:
- Otoscopy – an examination that involves looking into the ear with an instrument called an otoscope and is performed in order to examine the tunnel that leads from the outer ear to the ear drum.
- Tympanometer – an instrument used to test the condition of the middle ear and the mobility of the ear drum.
- Audiometer – an instrument connected to a pair of headphones and a user feedback button which a patient presses if they hear a sound.
