Age-related hearing loss (presbycusis) is the gradual decline in hearing that occurs naturally with aging. It typically begins with high-frequency sounds and progresses over decades. This educational reference shows typical hearing threshold changes by age decade and frequency range — helping you understand which everyday sounds are affected at each stage.
Not a hearing test. This is an educational reference based on average population data. Individual hearing varies significantly. Consult an audiologist for an actual hearing assessment.

Risk Factors That Accelerate Hearing Loss
Understanding Age-Related Hearing Loss
The human ear can detect frequencies from roughly 20 Hz to 20,000 Hz, though this range narrows with age. Sound is measured in decibels (dB) and frequency in Hertz (Hz). Higher dB values indicate louder sounds; higher Hz values indicate higher-pitched sounds. Age-related hearing loss (presbycusis) almost always starts at the high end of the frequency spectrum.
How Hearing Loss Is Measured
An audiogram plots hearing threshold (the softest sound detectable) across frequencies. Normal hearing is 0–20 dB across all frequencies. The degree of hearing loss is classified as: mild (21–40 dB), moderate (41–70 dB), severe (71–90 dB), and profound (>90 dB). Age-related loss typically shows a "ski slope" pattern — good low-frequency hearing that drops sharply at higher frequencies.
Why Consonants Become Hard to Understand
Speech intelligibility depends more on hearing consonants than vowels. Consonants like S, F, SH, TH, P, and T are primarily high-frequency sounds (2,000–8,000 Hz). When high-frequency hearing declines, speech may sound muffled — you can hear that someone is talking but cannot distinguish what they are saying. This explains why people with presbycusis often say "I can hear you, but I can't understand you."
Protecting Your Hearing
The most effective protection strategy is limiting noise exposure. Wear hearing protection when exposed to sounds above 85 dB (lawn mowers, concerts, power tools). The "60/60 rule" for headphones: keep volume at 60% or below for no more than 60 minutes at a time. Cochlear hair cells, once damaged, do not regenerate — protection is permanent, and rehabilitation (hearing aids) only compensates for lost function.

Is this hearing loss guide free?
Yes, completely free with no signup required. All calculations run locally in your browser.
Is this a real hearing test?
No. This is an educational reference guide that shows typical hearing threshold changes associated with age-related hearing loss. It is not a clinical audiogram or hearing test. For an accurate assessment of your hearing, see an audiologist.
What is presbycusis?
Presbycusis (age-related hearing loss) is the gradual decline in hearing ability that occurs naturally with aging. It typically begins with high-frequency sounds (above 4,000 Hz) and progressively affects speech frequencies over time. It is the most common sensory disorder in older adults, affecting about 1 in 3 people over 65.
At what age does hearing typically start declining?
Measurable high-frequency hearing loss can begin as early as the late 20s or 30s, particularly for very high frequencies (8,000+ Hz). Significant hearing loss affecting speech comprehension typically becomes noticeable in the 50s and 60s. The rate of decline varies significantly based on genetics, noise exposure history, and overall health.
What sounds are most affected by age-related hearing loss?
Age-related hearing loss typically affects high-frequency sounds first: consonants like S, F, TH, SH, and H (which carry speech clarity), birdsong (typically above 4,000 Hz), telephone ringtones, and high-pitched voices. Low-frequency sounds like vowels, thunder, and bass sounds are typically preserved longest.
Can age-related hearing loss be reversed or slowed?
Presbycusis itself cannot currently be reversed, though researchers are investigating regenerative approaches. However, the rate of decline can be slowed by protecting ears from loud noise (the single most impactful modifiable factor), managing cardiovascular health (poor circulation contributes to cochlear damage), and treating any reversible causes.
When should I see an audiologist?
Consider seeing an audiologist if you frequently ask people to repeat themselves, struggle to follow conversations in noisy environments, turn the TV up louder than others prefer, or miss hearing common sounds. Hearing aids are highly effective and modern devices are nearly invisible — early intervention yields better outcomes than waiting.
