Medical disclaimer | The Ear Lab

If you have any of these symptoms, see a clinician this week:

Sudden hearing loss in one or both ears (hours to days). Medical emergency, treatment window is ~72 hours.
Tinnitus in only one ear, especially asymmetric.
Pulsatile tinnitus that beats with your heart.
Vertigo or balance loss with hearing changes.
Ear pain, drainage, or fullness lasting more than 48 hours.
Hearing change after head injury, loud noise, or starting a new medication.

What this site is

The Ear Lab is an independent editorial publication. We publish plain-language summaries of hearing-health research and build browser-based educational tools that implement standard audiology procedures. Our goal is to help you understand what is happening, ask better questions of your clinician, and follow research with less mystery.

What this site is not

Not a clinic. We do not see patients, take histories, examine ears, run audiograms, or provide opinions on your specific symptoms.
Not a diagnosis. Reading an article does not establish a doctor-patient relationship.
Not a treatment recommendation. Where an article discusses a therapy (CBT, TRT, hearing aids, masking), we describe the published evidence, not whether YOU should pursue it.
Not a substitute for an audiologist or ENT. If anything on this site applies to you, the right next step is almost always to see one.

The tools are educational, not diagnostic

The Tinnitus Frequency Matcher can suggest where your tinnitus pitch sits, but it cannot detect hearing loss, rule out a tumor, identify ototoxic medication exposure, or replace clinical pitch matching in an audiometric booth.
The hearing-range test indicates the high-frequency limit your specific speakers / headphones / browser can reproduce. That is correlated with but not equivalent to your true hearing threshold.
The NIOSH noise-dose calculator implements the published NIOSH and OSHA formulae for educational comparison, but does not substitute for a calibrated dosimeter in workplace assessment.

No supplement, device, or cure endorsement

You will encounter web ads and YouTube creator pitches for "tinnitus cure" supplements, sound-frequency devices, MLM-style hearing programs, custom audio downloads, and supplement stacks. The Ear Lab does not endorse any of these. Where the published evidence base is weak (ginkgo, zinc for non-deficient patients, binaural beats, hyperbaric oxygen for non-acute cases), we say so. Where it is reasonable (CBT, TRT, hearing aids for hearing-loss-related tinnitus, NIH/NIDCD-supported sound therapy), we say that too.

Compliance rails

Our editorial pipeline rejects the following words and phrases before publication: cure, cures, treat, treats, heal, heals, healing, fix, fixes, reverse, eliminate, guaranteed, proven to, miracle, doctor-approved, FDA, clinically proven. If you see any of these on this site without explicit qualification, write to us, it is a bug.

If you act on something here

You read at your own risk. If you reduce concert hearing-protection use based on something we wrote, that is your decision and we cannot accept liability for the consequences. If you skip an audiologist appointment because we made you feel reassured, that is dangerous. Please see a clinician.

Urgent symptom routing

United States: contact your primary care provider for urgent ENT or audiology referral. Urgent-care clinics can start steroid treatment for sudden sensorineural hearing loss.
United Kingdom: contact your GP today, or call NHS 111. Sudden sensorineural hearing loss is treated as an urgent pathway.
Other countries: contact your usual route to an ENT specialist. Sudden hearing loss is treated with urgency in most healthcare systems.

Editorial corrections

If you spot a factual error, contact us via the contact page. We publish dated corrections at the top of affected articles and keep a public changelog. We do not silently edit live articles to fix errors.
