Ask around about hearing aids and you will hear conflicting advice. Some people say they keep hearing loss from getting worse, while others warn that wearing them will weaken your hearing. At McLean Hearing Center on Sherry Lane in Dallas, audiologists Ryan Dunkin, Au.D., and Darcy Dockery, Au.D., and audioprosthologist and licensed hearing instrument specialist Angela McLean, ACA, can evaluate your hearing, explain what is causing changes, and help you see what hearing aids can and cannot do. While hearing aids can’t reverse hearing loss, they can amplify sounds so you hear clearly.
Why Can’t Damaged Hair Cells Restore Lost Hearing?
Damaged hair cells can’t restore lost hearing because the tiny hair cells of the inner ear do not regenerate once they are damaged or lost, which is why most hearing loss is permanent. Hearing aids cannot repair that damage, but they can make sounds easier to hear and help patients communicate more comfortably.
Sound travels through the outer and middle ear to the cochlea, a snail-shaped structure in the inner ear. Thousands of hair cells inside the cochlea convert sound vibrations into electrical signals, which travel along the auditory nerve to the brain.
Hair cells can be damaged by:
- Natural aging
- Exposure to loud noise over time or from a single loud event
- Genetic factors
Some hearing problems, such as earwax blockage or certain middle ear conditions, may be treatable. A hearing evaluation helps identify the type and degree of hearing loss so patients can explore the most appropriate options.
Do Hearing Aids Change the Course of Hearing Loss?
Hearing aids generally do not change the physical course of hearing loss, because they cannot prevent or slow its progression. What they may do is help preserve the brain’s ability to understand speech by keeping the auditory system active and engaged.
When hearing loss goes untreated, the brain receives less sound information over time. This reduced stimulation, known as auditory deprivation, can make the brain areas responsible for processing sound less active. As a result, patients may find speech increasingly difficult to understand, even after they begin wearing hearing aids.
Consistently wearing properly fitted hearing aids gives the brain the regular sound input it needs to process. This helps maintain speech understanding, which is often more important than simply making sounds louder. Because many people wait years after noticing hearing difficulties to seek care, earlier evaluation can make a meaningful difference.
What Do Hearing Aids Do for Speech Understanding?
Hearing aids improve speech understanding by amplifying the specific frequencies a patient has difficulty hearing. Rather than making every sound louder, modern digital hearing aids are programmed to match each patient’s hearing loss, listening needs, and surroundings.
Many speech sounds, particularly consonants such as “s,” “f,” and “th,” fall in higher frequencies that are often the first affected by hearing loss. When these sounds are difficult to hear, words can blend together or seem mumbled. By restoring access to them, hearing aids help make speech clearer and easier to follow.
Many hearing aids also include features designed to support communication, such as:
- Noise reduction to help in busy environments
- Speech enhancement to emphasize voices
- Feedback suppression to reduce whistling
- Automatic adjustments as listening environments change
Hearing aids cannot eliminate all background noise, and some hearing difficulty may remain. Adjusting to amplified sound also takes time. Wearing hearing aids consistently and sharing feedback with your hearing care provider helps you get the most benefit from your devices.
When Should Hearing Aid Wearers Have Their Hearing Rechecked?
Hearing aid wearers should have their hearing rechecked whenever hearing seems to decline, although a decline while wearing properly fitted hearing aids is most likely due to the natural progression of hearing loss rather than the devices themselves. Correctly fitted and programmed hearing aids are designed to support hearing, not damage it.
Some patients notice that sounds seem quieter or more distant when they remove their hearing aids. This happens because the brain becomes accustomed to clearer, amplified sound. It does not necessarily mean hearing has worsened, but any noticeable change should be evaluated.
Hearing aids include maximum output limits to keep amplification safe. Problems may occur when devices are too loud, poorly programmed, or not designed for the patient’s hearing loss. You should never wear hearing aids that belong to someone else. Distorted, uncomfortable, or overly loud sounds may indicate a need for adjustment.
Schedule a follow-up appointment if you notice:
- More difficulty understanding conversations
- Sounds that seem distorted or uncomfortable
- Frequent volume increases to hear clearly
- Changes in hearing in one ear
An updated hearing test can confirm whether hearing has changed. In many cases, our hearing care team can reprogram existing hearing aids to address new hearing needs.
How Does Our Hearing Care Team Narrow Down Your Hearing Aid Options?
Our hearing care team narrows down your hearing aid options by evaluating your hearing, discussing your communication needs and lifestyle, recommending appropriate devices, and programming them for your specific hearing loss.
This begins with a comprehensive hearing evaluation to determine the type and degree of hearing loss. From there, Ryan Dunkin, Darcy Dockery or Angela McLean may ask where you have the most difficulty hearing, how active your lifestyle is, and which features may be most useful.
Hearing aids vary in size, style, features, and price, including behind-the-ear, in-the-ear, and in-the-canal designs. During your hearing aid fitting, our team can explain each option and help you choose a device that fits your hearing needs, comfort, and budget.
