Hearing Loss

There are two main types of hearing loss and many causes. In this section, we will explore the different types of hearing loss and some of the causes.

Sensorineural Hearing Loss

Hearing loss that includes the inner ear (cochlea or auditory nerve) is considered a sensorineural hearing loss. This is sometimes referred to as a sensory hearing loss or a nerve hearing loss. The majority of our patients have this type of hearing loss and is most common in older adults. There are many types of sensory hearing loss but the most common is presbycusis, or hearing loss due to old age. When we lose hearing in older age, we tend to lose the ability to hear high frequency sounds first. Patients with high frequency hearing loss tend to have more difficulty with women and children’s voices because their voices are typically in the higher pitch range. This causes the patient to hear low frequency sound (or background noise) better than speech. These patient’s tend to hear worse in groups, meetings, and background noise.

Hearing loss in Cochlea

Hearing loss resulting from the cochlea include:

  • Presbycusis
  • Noise Induced Hearing Loss

Hearing loss in Auditory Nerve

Hearing loss resulting from the Auditory Nerve include:

  • Auditory Neuropathy
  • Auditory Dyssynchrony
