What does an audiologist do that a GP cannot?

Audiologists perform full diagnostic audiometry including pure-tone testing, speech recognition, immittance measures (tympanometry and acoustic reflex), and otoacoustic emissions. They can also assess tinnitus perceptual characteristics (pitch, loudness, maskability) and provide hearing aid fitting, aural rehabilitation, and tinnitus management counseling. GPs typically perform basic ear examination and can manage straightforward conditions like earwax but refer complex hearing and tinnitus cases to audiology or ENT.

Should I see an audiologist or an ENT for tinnitus?

Both can evaluate tinnitus, but they approach it differently. Audiologists perform the detailed auditory testing that characterizes the condition. ENTs (otolaryngologists) investigate potential underlying medical causes requiring medical or surgical treatment. For most tinnitus cases without red-flag features, an audiologist is an appropriate first specialist. AAO-HNS guidelines suggest ENT referral when tinnitus is unilateral, pulsatile, or accompanied by dizziness or neurological symptoms.

How urgent is a sudden hearing loss?

Sudden sensorineural hearing loss is a medical emergency. The AAO-HNS clinical practice guideline recommends initiating treatment within 72 hours of onset for the best chance of recovery. Same-day emergency assessment is appropriate rather than waiting for a scheduled audiology appointment.

Can I see an audiologist without a GP referral?

In many countries, including the United States, audiologists can be seen directly without a GP referral. In the UK, NHS audiology services typically require a GP referral, though private audiology practices accept self-referrals. Checking the access pathway in your country or health system is the practical first step.

What should I bring to an audiology appointment?

A list of current medications (several are ototoxic), your noise exposure history (occupational and recreational), a timeline of when symptoms started and how they have changed, and if available, results from any previous audiometric testing. If tinnitus is a concern, keeping a one-week diary of loudness, quality, and triggering conditions before the appointment gives the audiologist useful baseline information.

When to see an audiologist: 7 specific triggers

Most people have had a moment of ear ringing after a loud event, or a day or two of muffled hearing during a cold. These experiences are common and usually resolve without intervention. Knowing which symptoms cross the line into territory that warrants a specialist evaluation is genuinely useful, because delayed assessment for certain conditions significantly affects outcomes.

This article covers seven specific clinical triggers that the AAO-HNS, NIDCD, Mayo Clinic, and NHS identify as reasons to seek audiological assessment, along with the rationale for each.

Trigger 1: Sudden hearing loss in one or both ears

Sudden sensorineural hearing loss (sudden SNHL) is defined as a loss of 30 dB or more across at least three consecutive audiometric frequencies occurring within 72 hours. It is a medical emergency. The AAO-HNS clinical practice guideline recommends that patients who notice sudden unilateral hearing loss seek evaluation immediately, not wait for a scheduled appointment.

The urgency is driven by treatment windows. Systemic corticosteroids, the primary treatment for sudden SNHL, are most likely to be effective when started within 72 hours of onset. The window narrows sharply after two weeks. For this one trigger, seeing an audiologist or ENT the same day the symptom is noticed is appropriate.

Sudden hearing loss accompanied by a sensation of ear fullness on waking, sometimes mistaken for water in the ear, is a common presentation that people delay acting on. The delay is costly.

Trigger 2: Tinnitus that is unilateral or pulsatile

Tinnitus affecting only one ear, or tinnitus that beats in time with the pulse, warrants specialist assessment to rule out structural causes.

Unilateral tinnitus is one of the presenting symptoms of vestibular schwannoma (acoustic neuroma), a benign tumor of the eighth cranial nerve. The AAO-HNS guideline recommends MRI with gadolinium contrast to evaluate for retrocochlear pathology when tinnitus is unilateral, particularly when accompanied by asymmetric hearing loss or unsteadiness.

Pulsatile tinnitus has a separate differential that includes vascular abnormalities such as venous sinus stenosis, arteriovenous malformations, or glomus tumors. These causes are far less common than idiopathic tinnitus but require different evaluation, including vascular imaging in some cases.

Trigger 3: Tinnitus accompanied by dizziness or balance disturbance

The combination of tinnitus with vertigo, unsteadiness, or episodic spinning sensation raises the possibility of inner ear conditions including Meniere’s disease, a disorder characterized by endolymphatic hydrops that produces fluctuating hearing loss, tinnitus, and vestibular episodes.

Vestibular symptoms warrant prompt evaluation because they carry fall risk and functional impairment beyond the auditory symptoms. Audiological and vestibular testing together characterize the profile needed to differentiate among inner ear conditions with overlapping presentations.

Trigger 4: Hearing loss that has affected function for more than three months

If difficulty hearing speech in conversation, in noise, or on the telephone has persisted for three months or more without investigation, an audiological assessment is appropriate. This timeline excludes the typical short-term hearing change associated with upper respiratory infections, which usually resolves within a few weeks as eustachian tube function normalizes.

NHS guidance and Mayo Clinic both note that untreated hearing loss has established associations with accelerated cognitive decline and social withdrawal in older adults. Earlier intervention with appropriate amplification or treatment modifies both of these trajectories.

Trigger 5: Tinnitus causing significant distress or sleep disruption

Tinnitus that was previously mild but has become consistently intrusive, is significantly disrupting sleep onset or sleep maintenance, or is causing notable anxiety or concentration difficulty, merits evaluation. The AAO-HNS guideline distinguishes between tinnitus as a subclinical finding and tinnitus as a clinically significant problem requiring management.

An audiologist can characterize the tinnitus (pitch, loudness, maskability, residual inhibition), assess for concurrent hearing loss, and discuss management options that may include sound therapy, counseling, or referral to a tinnitus specialist.

Trigger 6: History of ototoxic medication use

Several medications are known to cause cochlear or auditory nerve damage, including certain aminoglycoside antibiotics, platinum-based chemotherapy agents, loop diuretics at high doses, and some antimalarial drugs. NIDCD and clinical pharmacology guidelines recommend baseline audiometric monitoring before starting these agents and periodic reassessment during and after treatment.

If you have received ototoxic treatment and have not had audiological follow-up, baseline audiometry provides a reference point for identifying any subsequent changes.

Trigger 7: Ear noise or hearing change following significant noise exposure

A single exposure to very loud sound (an explosion, a concert, a firearm discharge without protection) that results in tinnitus or muffled hearing lasting beyond 24 hours warrants assessment. Tinnitus or threshold shift that resolves within a few hours may represent a temporary threshold shift with no permanent damage. Symptoms persisting longer suggest the possibility of permanent cochlear injury.

Early documentation of the post-exposure auditory state establishes a baseline and allows any ongoing change to be tracked. For occupational exposures, early documentation may also be relevant for workers’ compensation purposes in applicable jurisdictions.

Audiologist vs. ENT: who to contact

For most of the triggers above, an audiologist is an appropriate first specialist. Audiologists perform the diagnostic testing that characterizes hearing and tinnitus. ENT (otolaryngology) referral is appropriate when medical or surgical treatment may be needed: suspected sudden SNHL requiring steroid treatment, unilateral tinnitus requiring imaging, pulsatile tinnitus requiring vascular evaluation, or ear infections requiring medical management. In many health systems, the audiologist and ENT work within the same clinical team.

If symptoms persist or change, see an audiologist or physician.
