Understanding Ear Ringing and What Causes It

Ear ringing, medically known as tinnitus, is the perception of sound in one or both ears when no external sound is present. The sound may be described as ringing, buzzing, hissing, roaring, whistling, or clicking. According to the National Institute on Deafness and Other Communication Disorders, approximately 15% of adults in the United States experience tinnitus, affecting roughly 50 million people. While tinnitus itself is not a disease, it is a symptom that indicates something is happening within the auditory system.

Tinnitus occurs due to changes in how the inner ear, auditory nerve, or brain processes sound signals. When hair cells in the inner ear become damaged, they may send irregular electrical signals to the brain, which interprets these signals as sound. Unlike external sounds, tinnitus originates from within your body, which is why no one else can hear it unless they have their own tinnitus. The condition can develop suddenly or gradually over time, and its characteristics vary significantly from person to person.

Common causes of tinnitus include exposure to loud noise, age-related hearing loss, earwax buildup, certain medications, head or neck injuries, and underlying medical conditions. Noise exposure is one of the most preventable causes—prolonged exposure to sounds above 85 decibels can damage the delicate hair cells in the inner ear. Other contributing factors include caffeine consumption, stress, anxiety, sleep deprivation, and jaw joint problems. Understanding these potential causes is important because identifying what triggers your tinnitus can help you work with a healthcare provider to develop a management strategy.

Tinnitus is classified into two main types: subjective and objective. Subjective tinnitus accounts for approximately 99% of cases and is only heard by the person experiencing it. Objective tinnitus is rare but can sometimes be heard by an examiner using a stethoscope placed against the ear or mastoid bone. Objective tinnitus may result from blood vessel problems, muscle contractions, or mechanical issues in the middle ear. Distinguishing between these types helps healthcare providers understand what is occurring and how to address it.

Practical Takeaway: Keep a journal documenting when your tinnitus occurs, what it sounds like, how long it lasts, and what you were doing before it started. Note any patterns related to stress, caffeine intake, sleep, or noise exposure. This information helps you and your healthcare provider identify potential triggers and develop strategies to reduce symptoms.

How Hearing Loss and Tinnitus Connect

A strong connection exists between hearing loss and tinnitus. Research indicates that approximately 90% of people with tinnitus also experience some degree of hearing loss. This relationship occurs because both conditions often stem from damage to the same structures—the hair cells in the inner ear. When these cells are damaged or destroyed, they cannot transmit sound signals properly to the auditory nerve and brain, resulting in both hearing difficulties and the perception of phantom sounds.

Age-related hearing loss, called presbycusis, is one of the most common causes of both hearing loss and tinnitus in older adults. According to the American Speech-Language-Hearing Association, one in three people over age 65 experiences hearing loss, and many of these individuals also report tinnitus. The gradual loss of hair cells that occurs with aging can lead to abnormal signaling in the auditory system, which the brain interprets as sound. Additionally, noise-induced hearing loss from occupational or recreational exposure to loud sounds frequently triggers tinnitus.

The relationship between these conditions suggests that protecting your hearing can help prevent both hearing loss and tinnitus. Strategies include wearing hearing protection in noisy environments, keeping volume levels moderate when using earbuds or headphones, and seeking treatment promptly if you suspect hearing loss. For people who already have both conditions, addressing the hearing loss through hearing aids or other devices may provide relief from tinnitus symptoms. Many individuals report that using hearing aids helps them hear environmental sounds more clearly, which can mask or reduce the perception of tinnitus.

Sudden hearing loss accompanied by new onset tinnitus warrants immediate medical evaluation. This combination can indicate various conditions ranging from inner ear inflammation to sudden sensorineural hearing loss, which may respond to treatment if addressed within days of onset. Conversely, gradual hearing loss combined with persistent tinnitus typically indicates chronic changes that require long-term management strategies rather than acute medical intervention.

Practical Takeaway: Schedule a hearing test with an audiologist or your primary care doctor if you experience new tinnitus or suspect hearing changes. A baseline hearing assessment helps document your current hearing status and provides information for comparison if your hearing changes in the future. Many insurance plans cover preventive hearing screenings, and some employers offer free hearing testing through occupational health services.

When to Seek Medical Attention for Ear Ringing

Most cases of tinnitus are not serious and do not require emergency care, but certain situations warrant prompt medical evaluation. You should contact a healthcare provider if your tinnitus appears suddenly, especially if it affects only one ear, as this may indicate an underlying condition requiring treatment. Sudden unilateral tinnitus (affecting one ear only) can be associated with sudden sensorineural hearing loss, which may respond to corticosteroid treatment if addressed within two weeks of symptom onset. Additionally, if tinnitus is accompanied by hearing loss, dizziness, ear pain, or a sensation of fullness in the ear, medical evaluation is important.

Tinnitus accompanied by neurological symptoms such as facial weakness, numbness, difficulty swallowing, or balance problems requires urgent medical attention. These symptoms could indicate conditions affecting the auditory nerve or brain that require specific diagnosis and treatment. Similarly, if your tinnitus is pulsatile—meaning it pulses in rhythm with your heartbeat—you should be evaluated to rule out vascular causes. Pulsatile tinnitus sometimes indicates high blood pressure, blood vessel abnormalities, or other circulatory conditions that respond to targeted medical management.

Schedule a regular appointment with your primary care doctor or an ear, nose, and throat specialist (otolaryngologist) if your tinnitus is bothersome, persistent, or worsening over time. These providers can perform examinations, order appropriate testing such as audiometry or imaging, and discuss treatment options specific to your situation. An audiologist can also provide valuable assessment of your hearing and evaluation of how tinnitus affects your daily functioning. Keeping track of your symptoms and their impact on sleep, concentration, mood, and quality of life helps your healthcare provider understand the severity of your condition.

During your medical evaluation, be prepared to describe the characteristics of your tinnitus in detail. Information about when it started, whether it is constant or intermittent, what it sounds like, whether it affects one or both ears, and what makes it better or worse all helps guide diagnosis. Additionally, inform your healthcare provider about any recent changes in health, new medications, head injuries, or exposure to loud noise, as these details often prove relevant to determining the cause.

Practical Takeaway: Before your appointment, write down a description of your tinnitus symptoms, when they started, what makes them worse or better, and how they affect your daily activities. List any medications you take, including over-the-counter products and supplements. Bring information about any recent illness, injury, or stressful life events. This preparation helps your healthcare provider gather the information needed to assess your situation effectively.

Medical Tests and Diagnostic Procedures for Tinnitus

When evaluating tinnitus, healthcare providers typically begin with a medical history and physical examination of the ears. Your doctor will look inside your ears using an otoscope to check for earwax buildup, infection, or damage to the eardrum. They will also perform simple hearing checks in the office, such as asking you to repeat whispered words or noting your response to snapping fingers near each ear. These basic assessments help determine whether hearing loss is present and whether further testing is needed.

Audiometry is one of the most common tests for people with tinnitus. This painless test, performed by an audiologist in a soundproof booth, measures your ability to hear sounds at different frequencies and volumes. During audiometry, you wear headphones and respond when you hear tones played at varying pitches and loudness levels. The results create an audiogram—a graph showing your hearing thresholds across different frequencies. This test reveals whether hearing loss is present, what type of hearing loss it is (conductive or sensorineural), and whether it correlates with your tinnitus.
