Why Do I Hear Ringing in My Ears? Common Causes of Tinnitus
Learn what can cause ringing in your ears, how tinnitus is connected to hearing loss, and when persistent or unusual sounds should be checked by a professional.
You are sitting in a quiet room when you suddenly notice it.
A ringing sound. Maybe it's a faint buzz, a high-pitched tone, a hiss, or even a low humming noise.
You look around, but nothing is making the sound.
This experience is commonly known as tinnitus. It can happen occasionally and disappear on its own, or it can become a recurring sound that is difficult to ignore.
Tinnitus is not a disease by itself. It is a perception of sound that does not come from an outside source. People may hear ringing, buzzing, clicking, humming, roaring, or other sounds in one ear, both ears, or somewhere in their head.
For many people, tinnitus is manageable. But understanding why it happens can help you decide when it is simply something to monitor and when it deserves professional attention.
What Exactly Is Tinnitus?
Tinnitus is sometimes described as "hearing something that isn't there," but that doesn't mean the experience is imaginary.
The sound is real to the person experiencing it. The difference is that there is no corresponding external sound that other people can hear.
Tinnitus can be temporary or ongoing. It may come and go, remain constant, change in volume, or sound different from one day to another. Some people barely notice it, while others find that it interferes with sleep, concentration, or their mood.
The experience can also vary considerably from person to person.
One person may hear a high-pitched ringing, while another notices a low buzzing or whooshing sound.
What Causes Ringing in the Ears?
There isn't one single cause of tinnitus.
Several conditions and situations can be associated with it.
Exposure to loud noise
A loud concert, power tools, fireworks, machinery, or other intense sounds can trigger temporary ringing.
Repeated exposure to loud sounds can also damage the delicate structures involved in hearing and increase the risk of both hearing loss and tinnitus.
You may notice ringing after leaving a particularly loud environment. Sometimes it fades relatively quickly.
That is not necessarily something to ignore, though. Repeated episodes after loud noise can be a reminder that your ears are being exposed to more sound than they can comfortably handle.
Hearing loss
Tinnitus and hearing loss frequently occur together.
Age-related changes and long-term exposure to loud sounds can affect the inner ear and the way sound signals are processed. Tinnitus may sometimes be one of the first noticeable signs that hearing has changed.
This can be confusing because you might not think you have a hearing problem.
You may still hear conversations, television, and everyday sounds normally in quiet situations. The problem may become more obvious in restaurants, group conversations, or other environments where there is competing background noise.
Earwax buildup
Something as simple as earwax blocking the ear canal can sometimes contribute to tinnitus.
When the blockage is removed, the ringing may improve if the earwax was responsible for the problem. This is one reason a healthcare professional may examine the ear before looking for more complicated explanations.
It's generally better not to try to dig deep into your ear with cotton swabs or other objects. Doing so can push wax farther into the ear canal or injure the ear.
Ear infections and other ear problems
An ear infection or fluid affecting the ear can sometimes be associated with tinnitus.
If ringing appears together with ear pain, discharge, pressure, or noticeable hearing changes, it is worth having the ear examined rather than assuming the symptoms will simply disappear.
Certain medications
Some medications can cause or worsen tinnitus in certain people.
The NIDCD lists several types of medications that have been associated with tinnitus, including some anti-inflammatory drugs, antibiotics, cancer treatments, antimalarial drugs, and antidepressants.
That does not mean you should stop taking a medication because you develop ringing.
If you suspect a medication may be involved, speak with the healthcare professional who prescribed it. They can determine whether the medication, dose, or another factor could be contributing.
Jaw or head and neck problems
Tinnitus can sometimes be associated with problems involving the jaw joint or injuries affecting the head or neck.
The jaw joint is located close to the ear, and certain jaw problems can affect or worsen tinnitus in some people.
This is one reason tinnitus can sometimes change when you move your jaw, neck, or head.
Why Does Tinnitus Sometimes Seem Louder at Night?
Many people notice tinnitus more when the environment becomes quiet.
During the day, there may be conversations, traffic, appliances, television, music, and other sounds competing for your attention.
At night, there may be very little external sound.
That doesn't necessarily mean the tinnitus has suddenly become stronger. You may simply notice it more because there is less competing sound.
For some people, a quiet background sound can make tinnitus less noticeable. The NIDCD describes sound generators, fans, radios, and smartphone sound apps as options that some people use to make tinnitus easier to tolerate, particularly when trying to sleep.
Can Stress Make Tinnitus Worse?
Tinnitus can affect concentration, sleep, and mood, and those effects can make the experience more difficult to manage.
For some people, paying close attention to the sound can make it feel more intrusive. Stress and poor sleep may also make it harder to cope with the noise.
This does not mean tinnitus is simply caused by stress.
Rather, there can be a relationship between the sound itself and how strongly it affects your daily life. Behavioral approaches such as cognitive behavioral therapy can help some people reduce the distress associated with tinnitus.
Is There a Cure for Tinnitus?
There is currently no single cure that eliminates tinnitus for everyone.
That can sound discouraging, but it doesn't mean nothing can be done.
The most useful approach depends on what is causing the tinnitus and how much it affects the person experiencing it.
If an underlying problem such as earwax or an ear infection is responsible, treating that problem may reduce or eliminate the tinnitus.
For people who have hearing loss, hearing aids can sometimes make tinnitus less noticeable by increasing awareness of sounds around them. Sound therapy and behavioral therapies can also help some people manage the condition.
It's also important to be skeptical of products that promise to permanently "cure" tinnitus.
The NIDCD notes that although vitamins, herbal extracts, and dietary supplements are often marketed as tinnitus cures, none has been proven to be effective as a general treatment for tinnitus.
What Can You Do to Protect Your Hearing?
Even though not every case of tinnitus can be prevented, protecting your ears from excessive noise is one practical step you can take.
If you're around loud sounds:
- Turn the volume down when possible.
- Move farther away from loud speakers or machinery.
- Take breaks from loud environments.
- Use appropriate hearing protection when loud noise cannot be avoided.
- Give your ears time away from prolonged loud sound.
Repeated exposure to hazardous noise can contribute to permanent hearing damage and tinnitus.
This is especially important if you regularly work around loud machinery, attend concerts, use power tools, or listen to music at high volume.
When Should You Get Ringing in Your Ears Checked?
Occasional ringing after loud noise may disappear without treatment.
Persistent or recurring tinnitus, however, is worth discussing with a healthcare professional, particularly if you also notice hearing changes.
A professional can examine your ears, look for things such as earwax or infection, review your medical history and medications, and arrange a hearing assessment when appropriate.
There are also situations where tinnitus should be assessed more urgently.
Seek prompt medical attention if tinnitus occurs with sudden hearing loss, significant dizziness, facial weakness, or after a head injury. Tinnitus that beats in time with your pulse also warrants urgent medical evaluation.
These situations do not necessarily mean something serious is happening, but they should not simply be ignored.
Pay Attention to What Your Ears Are Telling You
Ringing in your ears can be surprisingly easy to dismiss.
You might blame it on getting older, a loud concert, stress, or simply having a bad night of sleep.
Sometimes there is a straightforward explanation. Other times, tinnitus can be connected to hearing loss or another condition that deserves attention.
The important thing is not to assume that every case is the same.
Protect your hearing from excessive noise, pay attention to changes in your hearing, and have persistent or unusual symptoms evaluated when appropriate.
You don't necessarily need to be worried every time you hear a brief ringing sound.
But if the noise keeps coming back, becomes difficult to ignore, or appears alongside other changes in your hearing or balance, finding out why is a much better approach than simply learning to live with the uncertainty.
