Hearing Loss Found in 84% of Adults Over 60 in New Audiometry Study

An audiometric study of 1,000 adults aged 60 and older finds hearing loss in 84 percent, with high frequencies declining almost twice as fast as low and mid tones each decade.

Hearing tends to fade so gradually with age that many people cannot say when the change began. Family members repeat themselves, the television creeps louder, and busy restaurants become harder work, yet the person at the center of it often feels their hearing is fine. Large studies that measure hearing directly, rather than relying on self-report, are one of the best ways to see what is actually happening inside aging ears.

A team of researchers in China has now published one of the more detailed recent snapshots, testing the hearing of 1,000 adults aged 60 and older and mapping how thresholds shift decade by decade, frequency by frequency, and between men and women.

Background: Why the Researchers Looked at This

Age-related hearing loss, known medically as presbycusis, is the gradual decline in hearing that comes with getting older. It usually starts in the high frequencies, the range that carries consonant sounds like s, f, and th, which is why aging listeners often say they can hear people talking but cannot make out the words. Untreated, it is linked to social withdrawal and a lower quality of life, which makes accurate identification a public health priority.

In 2020, the World Health Organization updated its criteria for defining and grading hearing loss, lowering the bar for what counts as impairment. One open question was how much difference the new criteria would make in practice: how many older adults who passed under the old definition would now be flagged as having hearing loss.

The researchers also wanted to untangle two patterns that smaller studies had hinted at: that the highest frequencies deteriorate fastest, and that men and women age into hearing loss along different paths.

How the Study Was Done

Between March 2022 and January 2023, 1,000 adults aged 60 and older attending a tertiary otolaryngology clinic underwent an ear examination, tympanometry to check the middle ear, and pure-tone audiometry, the standard beep test performed in a sound booth. People with abnormal middle ear findings were excluded, so the results reflect the aging inner ear rather than treatable mechanical problems.

Hearing loss was defined and graded using the better ear's average thresholds at 0.5, 1, 2, and 4 kilohertz, following the WHO 2020 criteria. The team then compared thresholds across age groups from the 60s through the 90s, and between men and women, using standard statistical tests.

What the Researchers Found

Hearing loss was nearly universal in this clinic population. Overall, 84.1 percent of participants met the WHO 2020 definition, rising from 78.3 percent of people in their 60s to 100 percent of those over 90. Because these were patients visiting an ear, nose, and throat clinic, the figures run higher than in the general population, but the age trend is striking.

The high frequencies bore the brunt of the damage. Thresholds at 8,000 hertz worsened by about 11.7 decibels per decade of age, nearly double the 4.5 to 6.3 decibels per decade seen in the low and middle frequencies. The steepest overall drop came between the 70s and the 80s, when hearing shifted from a high-frequency pattern of loss toward a generalized decline across the whole range.

The study also documented a sex crossover. Women had better hearing than men in their 60s and 70s, but their hearing then deteriorated faster, so that by the 80s and 90s women's thresholds were comparable to or worse than men's. Finally, applying the WHO 2020 criteria substantially increased how many people were identified as having hearing loss, especially among adults in their 60s and 70s, the group most likely to be told their hearing was still normal under older definitions.

What It Means for People with Hearing Loss

The practical takeaway is that hearing change in later life is the rule, not the exception, and it starts where speech clarity lives. Because the highest frequencies fail first and fastest, the earliest sign is rarely silence. It is muddiness: voices that sound present but indistinct, especially where background noise competes with consonants.

The findings also argue for getting hearing checked earlier than most people do. Adults in their 60s and 70s were exactly the group most affected by the updated WHO criteria, meaning many people in that window have measurable loss that older standards would have waved through. A hearing test in your 60s establishes a baseline, and repeating it every few years catches the acceleration the study observed between the 70s and 80s.

When High Frequencies Fade First, Frequency-Specific Fitting Matters

A pattern of loss concentrated in the high frequencies calls for hearing help that can boost those frequencies specifically, rather than making everything louder. That is one reason FDA-OTC hearing aids, designed for adults with mild to moderate hearing loss, increasingly emphasize frequency-specific processing and personalization.

Panda Air, an earbud-style device with 16-channel processing and multi-band adaptive noise reduction, takes this approach. Its optional app can run an in-ear hearing test through the aid itself, measuring your hearing frequency by frequency and then shaping gain and frequency response to your profile, a design often described as app-tuned hearing aids or self-fitting OTC hearing aids. The app and test are entirely optional, and Air works out of the box without either.

Air is also built as a rechargeable hearing aid with a charging case, with fast charging and 60 hours of total use per case, plus Bluetooth for calls, TV, and music, a 5-year warranty, and a 45-day trial that begins when you receive it. One caveat from the research applies here: OTC devices are intended for mild to moderate loss, and the generalized decline this study observed in the oldest groups is best evaluated with a clinical fitting.

Limitations of This Research

This was a clinic-based sample, drawn from people who had already sought care at a tertiary otolaryngology department, so the 84.1 percent prevalence figure should not be read as a population estimate. The design was also cross-sectional: it compared different people at different ages at one point in time, rather than following the same individuals for decades, so the per-decade decline rates are inferred rather than directly observed.

The study was conducted at a single center in China, and patterns may differ across populations with different noise exposure, health profiles, and access to care. The published abstract does not report funding sources or conflicts of interest.

What to Do With This

If you are in your 60s or beyond and have not had a hearing test under the current WHO criteria, this study is a good reason to get one. High-frequency loss hides in plain sight, and knowing your own audiogram, which frequencies you hear well and which you do not, is the first step toward addressing it while the change is still mild.
