Types of Hearing Loss
 
ConductiveConductive Hearing Loss
  • Sound energy is blocked from reaching the inner ear normally.
  • Possible causes include: fluid behind eardrum, earwax build-up, perforated eardrum, fixation of middle ear bones, etc.
  • In many cases, it may be medically or surgically treatable.
  • Typically, these individuals obtain significant benefit from hearing aids; however, surgical correction is frequently an option if medically appropriate.
  • May receive significant benefit from osseointergrated implanted hearing aids if medical treatment or air conduction hearing aids are not appropriate.
SensorineuralSensorineural Hearing Loss
  • Inner ear (cochlea) and/or hearing nerve damaged so sound is not processed normally.
  • Possible causes include: noise, medications, disease, aging etc. In some cases (less than 10%), it is medically or surgically treatable.
  • These individuals often obtain significant benefit from hearing aids or other amplifying devices.
  • Cochlear implants often provide significant hearing to children and adults who do not receive benefit from hearing aids.
MixedMixed Hearing Loss
  • There is both a conductive and a sensorineural part to the hearing loss.
  • A portion of the loss may be medically or surgically treatable.
  • Typically, these individuals will obtain significant benefit from hearing aids or other amplifying devices.
