How is hearing loss tested?

A person’s hearing is usually tested via a series of different tests, including otoscopic examination, tympanometry, audiometry and speech testing. In audiometry, the audiologist identifies the softest sounds a person can hear across a range of frequencies.

Can I get hearing loss from an ear infection?

Ear infections can cause a temporary hearing loss which resolves when the infection clears. Chronic, repeated ear infections can in some cases lead to permanent hearing difficulties.

Is hearing loss hereditary?

Hearing loss can be caused by a large variety of different causes, which are either intrinsic (originating in the body), extrinsic (caused by external factors) or idiopathic (of unknown causes). One intrinsic cause of hearing loss is genetic, meaning that a gene or genetic mutation either directly causes the hearing loss or causes a syndrome or condition of which hearing loss is one symptom. Some genetic causes of hearing loss can be hereditary, i.e. passed down from the person’s parents and developed while the baby is in the womb.

Can hearing loss cause tinnitus?

Most cases of tinnitus result from sensorineural or conductive hearing losses, and people with a history of noise exposure are more likely to experience tinnitus. In a minority of cases (10-15%) people with tinnitus have normal audiometric results; however, there is growing evidence that many in this group may in fact have a sensorineural hearing loss which is not picked up on in standard hearing tests (see Hidden Hearing Loss). Some other less common potential causes of tinnitus, especially for those with normal audiometric results, include head injury and abnormal somatosensory activity.

Can hearing loss cause dizziness

There are many different potential causes of dizziness, some of which originate in or impact the Vestibular System (or the systems in our body which regulate our balance). As the Vestibular System is part of the inner ear, some vestibular-related causes of dizziness can also affect our hearing. Hearing loss in and of itself cannot cause dizziness, but both can be symptoms of the same cause. Examples of such diseases are Ménière’s Disease or Labyrinthitis which can be caused by viruses.
