Ear with numbers 2.PNG


  1. Sound travels through the outer ear canal before reaching the ear drum

  2. Vibrations at the ear drum are conducted through a chain of tiny bones in the middle ear, then into the cochlea

  3. The cochlea converts this energy into chemical signals that activate the nerve

  4. These signals travel through the central auditory pathways, finally reaching the brain where sound is perceived

Ear Exam


There are different types of hearing loss, depending on the cause and location of the problem:


  • Conductive hearing loss - Anything affecting the conduction of sound through the outer and/or middle ear can potentially cause conductive hearing loss. These can include wax buildup and middle ear infections to name a couple. Conductive hearing loss can often be resolved through medical treatment.

  • Sensorineural hearing loss - by definition, this type of hearing loss arises at the level of the cochlea or auditory nerve, but it almost always involves a loss of hair cells in the cochlea. This type of hearing loss is permanent and may require a hearing aid or cochlear implant depending on the severity of the hearing loss.


  • Mixed hearing loss - a combination of conductive and sensorineural hearing loss.
