Signs of Hearing Loss in Adults: When to See an Audiologist

What are the early signs of hearing loss?

Hearing loss tends to develop slowly, and the brain compensates for a surprising amount of time before the difficulty becomes noticeable. By the time most people seek help, the loss has often been present for years.

Common signs to watch for:

• Difficulty in background noise. Struggling to follow conversation in a restaurant, meeting, or crowded room is one of the most common early complaints.
• Frequently asking for repetition. If you regularly say "what?" or "could you say that again," your hearing may not be capturing speech clearly.
• Mishearing words. Thinking someone said something different from what they actually said — particularly mixing up consonants like S, F, and Th.
• Turning up the volume. Needing the television or phone noticeably louder than other people in the room prefer.
• Difficulty on the telephone. Phones strip away the visual cues (lip reading, facial expression) that partially compensate for hearing difficulty.
• Tinnitus. Ringing, buzzing, or hissing in the ears is frequently associated with hearing loss, though it can occur independently 2Ref 2Tunkel DE, Bauer CA, Sun GH, Rosenfeld RM, Chandrasekhar SS, Cunningham ER Jr, et al. (2014).Clinical Practice Guideline: Tinnitus.Association of tinnitus with hearing loss and its clinical evaluation.
• Exhaustion after conversation. Straining to hear is cognitively tiring; social fatigue is a real consequence of untreated hearing loss.

What causes hearing loss in adults?

Age-related hearing loss (presbycusis) is the most common form. It affects the high-frequency hair cells in the inner ear first, which is why consonants (which carry many high-frequency sounds) become harder to hear before vowels do. A 2024 clinical practice guideline from the AAO-HNS addresses age-related hearing loss specifically and outlines evidence-based evaluation and management 1Ref 1Tsai Do BS, Bush ML, Weinreich HM, et al. (2024).Clinical Practice Guideline: Age-Related Hearing Loss.Evidence-based evaluation and management of age-related hearing loss; support for audiological evaluation in older adults.

Noise exposure. Repeated or intense noise damages the same hair cells. Hair cells do not regenerate in humans, so this damage is permanent.

Ear infections and fluid. Chronic middle ear infections or persistent fluid (otitis media with effusion) cause conductive hearing loss — sound physically cannot reach the inner ear efficiently. This is usually reversible.

Sudden hearing loss. A rapid decline in hearing, especially in one ear, is a medical urgency. The AAO-HNS has a specific guideline for sudden sensorineural hearing loss that recommends urgent evaluation and prompt treatment consideration 3Ref 3Chandrasekhar SS, Tsai Do BS, Schwartz SR, Bontempo LJ, Faucett EA, Finestone SA, et al. (2019).Clinical Practice Guideline: Sudden Hearing Loss (Update).Sudden sensorineural hearing loss as a medical urgency requiring prompt evaluation and treatment.

Medications (ototoxic drugs). Certain antibiotics, chemotherapy agents, and high-dose aspirin can damage hearing. A clinician can review your medication list.

Earwax buildup. Excessive cerumen is a simple and often overlooked cause of temporary, reversible hearing reduction.

What does an audiology evaluation involve?

An audiologist is a specialist trained specifically in hearing assessment and rehabilitation. They are the right professional for a formal hearing evaluation.

A comprehensive hearing test (audiological evaluation) typically includes:

• Pure-tone audiometry: You listen through headphones and indicate when you can hear tones at different pitches and volumes. Results are plotted on an audiogram.
• Speech recognition testing: Determines how well you can understand words at various volumes.
• Tympanometry: A brief test of middle ear function using air pressure; it can detect fluid or earwax issues.
• Bone conduction testing: Separates inner ear problems from outer or middle ear problems.

Results help the audiologist classify the type, degree, and configuration of hearing loss — and recommend whether hearing aids, medical referral, or other management is appropriate 4Ref 4Valente M, Abrams H; American Academy of Audiology Task Force (2006).Guidelines for the Audiologic Management of Adult Hearing Impairment.Scope and components of audiological evaluation and management for adult hearing impairment5Ref 5Ferguson MA, Kitterick PT, Chong LY, Edmondson-Jones M, Barker F, Hoare DJ (2017).Hearing Aids for Mild to Moderate Hearing Loss in Adults.Hearing aids improve hearing ability and quality of life for adults with mild to moderate sensorineural hearing loss.

A Cochrane review found that hearing aids improved hearing ability and quality of life for adults with mild to moderate hearing loss 5Ref 5Ferguson MA, Kitterick PT, Chong LY, Edmondson-Jones M, Barker F, Hoare DJ (2017).Hearing Aids for Mild to Moderate Hearing Loss in Adults.Hearing aids improve hearing ability and quality of life for adults with mild to moderate sensorineural hearing loss.

When should I schedule an audiological evaluation?

The straightforward answer: if you have noticed any of the signs above, a hearing test is worthwhile. Hearing loss tends to be underreported and under-treated.

Specific situations that warrant prompt evaluation: - Any sudden change in hearing in one or both ears (within 72 hours is ideal for sudden hearing loss) - Hearing loss accompanied by dizziness or balance problems - Ear pain, drainage, or a feeling of fullness - Hearing that seems to fluctuate - Significant noise exposure history

For people without specific symptoms, the AAO-HNS age-related hearing loss guideline supports baseline audiological evaluation for older adults 1Ref 1Tsai Do BS, Bush ML, Weinreich HM, et al. (2024).Clinical Practice Guideline: Age-Related Hearing Loss.Evidence-based evaluation and management of age-related hearing loss; support for audiological evaluation in older adults. There is no universal age threshold, but many clinicians recommend it starting in the mid-50s or earlier with risk factors.

An audiologist can also provide hearing protection counseling, tinnitus management, and referral to an ENT (otolaryngologist) if a medical cause is suspected.
