Hearing loss can run in families, though you aren’t always as susceptible as your relatives. Island Better Hearing has been family owned since 1971, and our team of doctoral-level audiologists at our Schwab Road office in Melville can evaluate your hearing within the context of your family history, helping you understand how genetics may shape your hearing health. If hearing loss is a known condition in your family, prioritize early testing and protective habits to preserve your hearing and address changes sooner.
Is Most Genetic Hearing Loss Sensorineural?
Yes, most genetic hearing loss is sensorineural, meaning it involves the hair cells of the inner ear or the auditory nerve. It is caused by changes in genes that affect how the ear develops or functions, and it may be present at birth or develop later in life.
Experts divide genetic hearing loss into two categories. Nonsyndromic hearing loss accounts for about 70% of genetic cases and occurs without other medical symptoms. Syndromic hearing loss makes up the remaining 30% and occurs alongside other health conditions, such as Usher, Pendred, and Waardenburg syndromes.
How Is Hereditary Hearing Loss Passed Down to a Child?
Hereditary hearing loss is passed down to a child through the inheritance pattern of the specific gene involved, and that pattern sets the child’s chance of being affected. Depending on the pattern, the chance may range from no risk to 50% or higher, and in many cases, parents with normal hearing can still have a child with genetic hearing loss.
The main inheritance patterns include:
- Autosomal dominant: Only one changed gene from one parent is needed, giving each child a 50% chance of inheriting the condition.
- Autosomal recessive: Both parents carry one changed gene without having hearing loss themselves, giving each child a 25% chance of inheriting the condition.
- X-linked: The changed gene is on the X chromosome, so males are more likely to be affected, while females are often carriers.
- Mitochondrial: The condition is passed only by the mother and can affect all of her children.
Autosomal recessive inheritance accounts for about 80% of nonsyndromic genetic hearing loss, which explains why most infants with hearing loss are born to parents with normal hearing. Even within the same family, severity and age of onset can vary from one person to another.
Could Genetic Hearing Loss Begin Long After Newborn Screening?
Yes, genetic hearing loss can begin long after newborn screening, during childhood or later in adulthood, although some forms are noticeable from birth. Congenital forms are identified through newborn hearing screening, while progressive forms develop gradually over years or decades.
Congenital hearing loss affects up to three in every 1,000 babies, and inherited genetic factors contribute to about 60% of hearing loss in infants. In young children, signs may include not reacting to loud sounds, not turning toward voices, or delays in speech and language development.
Later-onset genetic hearing loss often develops slowly, which can make it easy to overlook. Adults may notice:
- Difficulty following conversations in noisy places
- Asking others to repeat themselves
- Turning up the television or phone volume
- Ringing or buzzing in the ears
Because gradual changes can go unnoticed, family members are often the first to recognize them.
Who Should Get Their Hearing Tested in Melville, and How Often?
Anyone who notices changes in their hearing should have it tested right away, and people with a family history of hearing loss may benefit from baseline testing and regular evaluations even before symptoms appear.
Almost all hospitals screen newborns for hearing loss within the first few days of life. Children who pass newborn screening but have a family history of hearing loss may still benefit from monitoring, since some genetic forms develop later. Our office also offers pediatric hearing tests for children who need follow-up.
For adults, a baseline hearing evaluation provides a reference point for tracking changes over time. Our audiologists can perform a comprehensive hearing test, discuss your family history, and recommend how often you should return for follow-up testing. When a genetic cause is suspected, they may recommend a referral for genetic counseling or testing. Currently, no genetic test can predict whether a person will develop age-related hearing loss, which makes regular hearing evaluations especially important.
How Can You Shield Your Hearing if Hearing Loss Runs in Your Family?
If hearing loss runs in your family, you can shield your hearing by limiting noise exposure, using hearing protection, reviewing medications with your healthcare providers, managing your overall health, and scheduling regular hearing evaluations.
Because some genes can make the inner ear more vulnerable to damage, avoiding additional strain is especially important. Wearing earplugs or earmuffs around loud equipment, concerts, or firearms and keeping headphone volume at moderate levels can reduce noise exposure. Some medications can affect hearing, so let your healthcare providers know about a family history of hearing loss before starting new prescriptions.
Overall health also plays a role. Conditions such as high blood pressure, heart disease, and diabetes may increase the risk of hearing loss, so managing these conditions supports long-term hearing health.
When hearing loss does develop, our audiologists can recommend options such as hearing aids and track changes over time to adjust your care as needed.
