Frequently Asked Questions
-
The three main types are conductive hearing loss, which affects the outer or middle ear; sensorineural hearing loss, which impacts the inner ear or hearing nerve; and mixed hearing loss, which is a combination of both.
-
Common symptoms include muffled hearing, difficulty understanding speech, especially in noisy environments, needing to turn up volume, and sometimes a feeling of fullness or pressure in the ear. Sounds may seem both faint and distorted.
-
Hearing problems can range from mild to profound hearing loss, and they may be temporary or permanent. Types include conductive, sensorineural, mixed, and central hearing loss, which relates to issues in the brain's processing of sound.
-
Not always. Sensorineural hearing loss can be unilateral (in one ear) or bilateral (in both ears), depending on the cause. It’s important to get a hearing test to determine the severity and location of the loss.
