What should you not do before a hearing test?

Avoid loud noise exposure, such as concerts, power tools or loud headphones, for around 16 hours beforehand, as it can temporarily affect your results. Let your clinic know if your ears feel blocked with wax. Bring a list of medications and, if you have one, a support person to help discuss the results.

Avoid loud noise before your hearing test

Loud noise exposure in the hours before a test can cause a temporary shift in your hearing thresholds, which may make your results look worse than your usual hearing. Try to avoid concerts, power tools, loud headphones or noisy workplaces for around 16 hours before your appointment where possible.

Tell your clinic about ear wax and blocked ears

If your ears feel blocked, full or muffled, mention this when you book or on arrival. Ear wax can affect test results, and your clinic may check and, if needed, arrange for wax removal before or as part of your visit.

What to bring to your appointment

• A list of current medications, including anything ototoxic your GP may have mentioned
• Details of any hearing aids you currently use, if applicable
• A support person, if you would like help remembering the discussion
• Any previous audiogram or hearing test results, if you have them

Should you avoid cotton buds or anything else?

There is no need to fast or change your diet before a hearing test. Also avoid cleaning your ears with cotton buds beforehand, since they can push wax deeper. If you use hearing aids, bring them along even if you plan to be tested without them, so your audiologist can review their fit and settings if relevant.

Is there anything you should do the morning of your test?

Beyond avoiding loud noise, no special preparation is needed. Eat and drink normally, take your usual medications unless your GP has advised otherwise, and arrive a few minutes early to complete any paperwork before your appointment starts.

What if you arrive with blocked ears anyway?

Your audiologist can still perform an otoscope check and advise you. If wax is significantly affecting the ear canal, they may recommend clearing it first for the most accurate result, or proceed with testing and note the limitation in your results.
