Sensory hearing loss happens when the inner ear or nerves that connect the ear to the brain don’t work right. This makes it hard for a person to hear sounds clearly, even if they are loud enough.

What causes sensory hearing loss?
Sensory hearing loss can result from aging, exposure to loud noise, genetic factors, ototoxic medications, head trauma, infections, or diseases like Meniere’s disease or acoustic neuroma.
What are the symptoms of sensory hearing loss?
Symptoms may include difficulty hearing conversations, trouble understanding speech, ringing in the ears (tinnitus), muffled or distorted sound perception, and increased difficulty hearing in noisy environments.
How is sensory hearing loss diagnosed?
Diagnosis typically involves a comprehensive hearing evaluation by an audiologist, including pure-tone audiometry, speech audiometry, tympanometry, and possibly imaging tests like MRI or CT scans.
What are the treatment options for sensory hearing loss?
Treatment options may include hearing aids, cochlear implants, assistive listening devices, auditory training, communication strategies, and management of underlying conditions contributing to hearing loss.
Sensory hearing loss, also known as sensorineural hearing loss, is a type of hearing impairment caused by damage to the inner ear structures (such as the cochlea) or the auditory nerve pathways that transmit sound signals to the brain. This damage can lead to a reduced ability to hear faint sounds, difficulty understanding speech, and a decreased capacity to differentiate between similar sounds. Approximately 90% of all hearing loss cases are attributed to sensory hearing loss.
Sensory hearing loss may be linked to various conditions. Understanding these associations can aid in early detection and treatment. Here are some common ones:
| Condition | Description |
|---|---|
| Genetic Disorders | Conditions like Usher syndrome and Waardenburg syndrome can cause sensory hearing loss. |
| Age-Related Hearing Loss | Presbycusis, or age-related hearing loss, often involves sensory hearing loss due to damage to inner ear hair cells. |
| Noise-Induced Hearing Loss | Exposure to loud noises over time can lead to sensory hearing loss. |
| Ototoxic Medications | Certain medications, like some antibiotics and chemotherapy drugs, can damage the sensory cells in the inner ear. |
Being aware of conditions associated with sensory hearing loss can prompt proactive measures such as regular hearing screenings and noise protection.
