Tinnitus spike? Why it suddenly gets louder, and what to do

Why tinnitus goes up and down

"Spike" isn't a medical word, but the experience is well described. NIDCD says tinnitus "may come and go or be present all the time," and that the sound "may be soft or loud and may be low or high pitched." ASHA's public guide adds that it "can change in volume or pitch."

Researchers have measured this by asking people to rate their tinnitus on their phones several times a day. In a 2017 study of 40 adults in JAMA Otolaryngology, tinnitus bother, loudness and stress "vary together over time." A larger study of 350 people using the TrackYourTinnitus app found tinnitus was rated louder and more distressing between midnight and 8 a.m. than later in the day, even after accounting for stress. So if your worst moments are in the middle of the night, you are not imagining it.

After a concert, a gym class, a loud drive

A spike after loud noise

This is the most clearly documented cause. NIDCD says loud noise exposure can cause tinnitus, and that the temporary hearing loss that often comes with it usually disappears 16 to 48 hours later. NIDCD also says noise-related tinnitus "may subside over time, but can sometimes continue constantly or occasionally."

Give your ears a quieter day or two, and limit loud noise, which NIDCD names as a way to avoid making symptoms worse. If it was a concert, our ears ringing after a concert guide walks through the first hours, the next day and the week after. If your hearing still feels dull or blocked after two days, book a hearing check rather than waiting it out.

When nothing obvious happened

Spikes "for no reason"

Often there is a reason, it just isn't loud. These are the ones the main health sources name:

• Stress. The NHS lists stress among things that can make tinnitus worse, and Tinnitus UK says it is "common for existing tinnitus to become worse during periods of high stress."
• Quiet. ASHA's guide says tinnitus may be more noticeable at night or in quiet places. The NHS advises against total silence.
• Earwax or an ear infection. NIDCD says blockage by earwax or fluid from an ear infection "can trigger tinnitus." Don't dig at it yourself; a doctor can check.
• Your jaw, head and neck. NIDCD says jaw clenching or tooth grinding can cause or worsen tinnitus, and that moving your head, neck or eyes can temporarily change the sound. The 2026 guideline calls this somatosensory tinnitus.
• Medicines. NIDCD lists some anti-inflammatories (including ibuprofen, naproxen and aspirin), certain antibiotics, anti-cancer drugs, anti-malaria drugs and antidepressants, especially at high doses. If a spike lines up with a new medicine, talk to your doctor or pharmacist before stopping it. Our medication checker can help you look one up.

One more thing that can feel like a spike: a sudden tone in one ear that fades within a few minutes, sometimes with a muffled feeling. The 2026 US guideline calls this "transient ear noise" and says it "does not typically require clinical management." If it lasts longer, keeps coming back or comes with hearing loss, get it checked.

What about caffeine and alcohol?

You will see coffee on almost every list of tinnitus triggers. The evidence doesn't back it up. In a 2010 double-blind trial of 66 people with tinnitus, caffeine "had no effect on tinnitus severity," and the researchers warned that withdrawal "might add to the burden of tinnitus." Tinnitus UK says there is "no scientific basis" for cutting caffeine out and suggests a moderate, steady intake instead. On alcohol, it says "the consensus is that alcohol is not a risk factor for tinnitus."

Everyone is different, so if you notice a link for yourself, log it. Just don't feel you have to give things up on principle.

Louder in one ear

NIDCD says tinnitus can be heard "in one ear, in both ears, and in your head," so one side being louder is common. Two things are worth knowing. First, sudden hearing loss "frequently affects only one ear," according to NIDCD, and is a medical emergency: if the louder ear also suddenly sounds muffled or quiet, get seen the same day. Second, even without that, a one-sided pattern is useful information. The AAO-HNSF guideline, updated in October 2026, says every patient with tinnitus should get a comprehensive hearing evaluation, so tell your doctor or audiologist which side it is.

What to do during a spike

• Add gentle sound. A fan, soft music or nature sounds in the background. The NHS says not to sit in total silence. Our tinnitus sounds guide can help you put a name to what you're hearing.
• Try not to monitor it. The NHS says focusing on tinnitus can make it worse. Do something absorbing instead.
• Turn the stress down where you can. A walk, slow breathing, an early night. The NHS suggests relaxing and keeping a normal sleep routine.
• Protect your ears from more noise while it settles.
• Write it down. Use the log below. It takes ten seconds.

If spikes keep coming back

See a doctor if your tinnitus is getting worse, happens regularly or constantly, or is affecting your sleep, concentration or mood. That is the NHS's advice. NIDCD suggests starting with your primary care doctor, who will check for earwax or fluid and may refer you to an ENT or an audiologist. Bring your log, and our tinnitus frequency matcher can help you describe the pitch.

For tinnitus that lasts six months or longer and affects your quality of life, the 2026 AAO-HNSF guideline recommends cognitive behavioral therapy, a hearing aid evaluation if you also have trouble hearing, and sound enrichment as an option. It recommends against routinely using medications or dietary supplements for tinnitus, and NIDCD says no vitamin or supplement has been proven to work. Our tinnitus treatment guide goes through each option.

Tinnitus can be exhausting. The guideline asks clinicians to check on emotional distress, so it's fine to say how much it's getting to you.
