Understanding the Journey: Navigating the Stages of Hearing Loss
If you or a loved one have hearing loss, you are probably used to hearing words like ‘I lost 40% hearing in my right ear’ or ‘my doctor told me I have a mild hearing loss’ or (our personal pet peeve) ‘they said my hearing is normal for my age’. Frankly—each of these is wrong. No member of Coastal Audiology Center will use any of these terms when describing hearing loss to a patient. And just to clarify—there is no such thing as ‘age-adjusted hearing loss’— you either have hearing loss or you don’t. There is no ‘sliding scale’ because of your age and there is no such thing as ‘normal hearing loss’—that is an oxymoron.
Understanding your diagnosis is the first step in any successful treatment plan. Using terms like ‘mild’ or ‘moderate’ do not have much meaning. Additionally, making incorrect statements like ‘40% loss’ does not help anybody and are inaccurate—until you are dead, and somebody goes poking around your ears and brain, a percentage should not be assigned to a hearing loss.
Like nearly all major medical conditions, a hearing loss diagnosis must be ‘staged’ to be best understood and to lay out realistic expectations and prognosis for treatment.
Stage 1
Early-stage hearing loss (15-40 decibels of loss) with some impact on cognitive function.
Patients with Stage 1 hearing loss are caught at the earliest phase of the disorder: thus, having the greatest prognosis for treatment. At this early stage, hearing loss may be beginning to show early signs of impacting cognitive function with some impacts on memory recall and name finding.
Although many people living with this hearing loss may consider it ‘just a nuisance’, it is important to understand that hearing loss is a progressive degenerative disorder that can significantly increase your risk of dementia, falling, and a host of other comorbid disorders.
Even at this earliest stage, these test results indicate marked damage to the nerves that connect the ear to the brain—which can have a host of downstream impacts, including tinnitus, difficulty following a conversation, and implication for memory loss and forgetfulness. Patient symptoms often include noticeable tinnitus (heard in the ears and/or head), subtle difficulty with details of speech (missing the beginning or end of what others are saying), some loss of environmental auditory awareness (i.e., difficulty hearing knocking at the door, the refrigerator, alarm, etc.). In addition, the person will notice conversation is becoming more difficult to follow in background noise (and when watching TV). Patients with Stage 1 hearing loss must be applauded for not waiting and catching this destructive disorder early—before it can fully infiltrate and wreak havoc on the brain.
Stage 1 hearing loss is correlated with a near 200% increased risk of developing cognitive decline and dementia. While that may be a shock to
If I asked you what you think the number one cause of hearing loss is, what would you say?
Most people answer noise, loud concerts, machinery, or years of exposure to high-volume environments. While noise absolutely plays a role, the truth may surprise you.
The number one cause of hearing loss is aging.
As we get older, our senses naturally begin to change. Vision declines. Hearing declines. This isn’t a personal failure, it’s a biological reality. But understanding how hearing changes as we age is the key to protecting it.
HOW HEARING REALLY WORKS: THE EAR-TO-BRAIN CONNECTION
Hearing isn’t just about your ears — it’s about your brain.
Inside the inner ear (which resembles a small snail-shaped structure called the cochlea), sound is converted into electrical signals. These signals travel along millions of neural connections from the ear to the brain.
In a healthy hearing system, these connections are strong, vibrant, and plentiful. Sound information flows easily, allowing the brain to interpret speech, background noise, and subtle details clearly.
WHAT HAPPENS TO HEARING AS WE AGE?
As we age, two critical changes occur in the hearing system:
1. FEWER NEURAL CONNECTIONS
Over time, the number of neurons connecting the ear to the brain decreases. Once a nerve is lost, it cannot be regenerated.
2. REDUCED QUALITY OF REMAINING NERVES
The nerves that remain become weaker. They’re less responsive, less vibrant, and less efficient at carrying sound signals.
This combination — fewer connections and lower-quality signals — is what we call hearing loss.
WHY HEARING LOSS IS CONSIDERED PROGRESSIVE
Hearing loss is medically defined as a progressive, degenerative condition.
A simple phrase explains it best:
“Use it or lose it.”
If the remaining ear-to-brain connections are not stimulated with clear, consistent sound, they continue to deteriorate. Without treatment, hearing loss doesn’t just continue, it accelerates.
The goal of treatment isn’t perfection.
The goal is to slow the progression and preserve brain health.
THE LINK BETWEEN HEARING LOSS AND COGNITIVE DECLINE
Treating hearing loss is one of the most powerful actions you can take for long-term brain health.
Research shows that:
1. Treating hearing loss is eight times more impactful than reducing alcohol consumption when it comes to lowering dementia risk.
2. It is four times more impactful than managing high blood pressure.
Untreated hearing loss forces the brain to work harder, diverting resources away from memory, focus, and cognition. Over time, this contributes to cognitive decline and dementia.
AGING IS INEVITABLE — DECLINE IS OPTIONAL
Aging happens to all of us. Decline does not have to.
If you’re reading this, you’ve already made a choice:
1. To stay engaged
2. To remain independent
3. To live fully and actively for as long as possible
Hearing care is not about “getting older.”
It’s about protecting how your brain works for the rest of your life.
