Your Brain Is Generating the Sound Post-concussion tinnitus (ringing, buzzing, hissing, or whooshing in the ears) affects 50-60% of concussion patients. In most cases, the sound originates from disrupted auditory processing in your brain, not from damage to your ears. The concussive force alters neural signaling along the auditory pathway from the brainstem through the auditory cortex, creating phantom sound perception (Kreuzer et al., 2014). Think of tinnitus as your brain's auditory system "misfiring" after the neural disruption of concussion. The damaged or altered neural circuits generate signals that your brain interprets as sound, even though no external sound source exists. This is the same mechanism behind tinnitus from other causes, but concussion creates the disruption through mechanical force rather than noise exposure. The reassuring reality: post-concussion tinnitus resolves in the majority of cases as the brain recovers. About 75% of people with post-concussion tinnitus see significant improvement within 3-6 months. Complete resolution is common for first-time concussions with no prior hearing issues. The Neuroscience Behind Post-Concussion Tinnitus Auditory cortex disruption. The auditory cortex processes sound signals from the ears. Concussive force disrupts the neural networks in this region, causing hyperexcitability. Overactive neurons in the auditory cortex fire spontaneously, creating the perception of sound. This hyperexcitability resolves as neural function normalizes during recovery. Brainstem auditory pathway damage. Sound signals travel from the cochlea through brainstem relay stations before reaching the auditory cortex. These brainstem structures are vulnerable to the rotational forces of concussion. Disrupted brainstem processing alters the signal reaching the cortex, contributing to tinnitus perception (Munjal et al., 2020). Central gain theory. When concussion reduces normal auditory input (even subtly), the brain compensates by "turning up the volume" on the auditory system. This increased central gain amplifies neural noise that was always present but previously below perception. The result: you hear the internal noise that the brain normally filters out. Vestibular-auditory overlap. The vestibular (balance) and auditory systems share anatomy in the inner ear and neural pathways in the brainstem. Concussion frequently affects vestibular function, and the anatomical proximity means auditory processing is often collaterally affected. This explains why tinnitus commonly accompanies dizziness after concussion. Cervicogenic contribution. Neck injury from the same mechanism that caused concussion affects blood flow through the vertebral arteries and creates muscle tension that influences auditory processing. Cervical dysfunction is an underrecognized contributor to post-concussion tinnitus and is directly treatable. Types of Post-Concussion Tinnitus High-pitched ringing. The most common type. Continuous or intermittent high-frequency tone, often described as a ring or whistle. Usually bilateral (both ears). Associated with auditory cortex hyperexcitability. Low-pitched buzzing or humming. Less common. Described as a hum, buzz, or drone. Tends to fluctuate with head position and fatigue levels. Often has a cervicogenic component. Pulsatile tinnitus. A rhythmic whooshing or throbbing sound synchronized with your heartbeat. This type warrants medical evaluation because it indicates altered blood flow near the ear structures. Most cases are benign (related to concussion-induced vascular changes), but some require imaging to rule out vascular abnormalities. Intermittent vs. constant. Intermittent tinnitus (comes and goes, worsens with fatigue or stress) has a better prognosis than constant tinnitus. If your tinnitus varies with activity level, sleep quality, and stress, those factors directly influence the neural hyperexcitability causing the sound. Cervical Mobility for Tinnitus Relief Neck tension and cervical dysfunction contribute to tinnitus. These exercises address the cervicogenic component: JME 1 Cervical rotation improves blood flow through the vertebral arteries that supply auditory brainstem structures. JME 3 Lateral flexion releases the lateral neck muscles whose tension affects auditory processing. JME 14 Chin tucks address the deep cervical tension that influences brainstem auditory relay stations. JME 5 Cervical extension mobilizes the upper cervical spine where vertebral artery flow is most affected by restriction. Start your 14-day free trial for cervical mobility routines that support tinnitus relief during concussion recovery. Upper Body Tension Release JME 42 Shoulder mobility releases the upper trapezius tension that contributes to cervicogenic tinnitus. JME 150 Thoracic rotation addresses the mid-back stiffness that increases cervical compensation and neck tension. JME 164 Scapular mobility reduces the shoulder girdle tension that refers into the neck and auditory structures. JME 152 Upper back extension opens the chest and reduces the forward head posture that compresses cervical structures. Managing Tinnitus During Recovery Sound enrichment. Complete silence makes tinnitus louder because there is no competing sound. Use low-level background sound: a fan, nature sounds, soft music, or a white noise app. The external sound gives your auditory system real input to process, reducing the brain's focus on the phantom signal. Sleep environment. Tinnitus is loudest at bedtime because ambient noise drops. Use a bedside sound machine or fan. Keep it at a volume just below the tinnitus level. This reduces the contrast between tinnitus and silence, making sleep onset easier. Stress management. Stress amplifies tinnitus by increasing neural excitability. The stress-tinnitus-stress cycle escalates quickly: tinnitus causes stress, stress worsens tinnitus. Breaking this cycle through relaxation techniques, gentle mobility, and cognitive strategies reduces tinnitus perception. Avoid loud environments. A concussed auditory system is more vulnerable to noise damage. Protect your hearing during recovery. Use earplugs in loud environments. Avoid concerts, loud restaurants, and headphone use at high volume. Additional auditory stress during recovery worsens tinnitus. Reduce caffeine and alcohol. Both substances alter blood flow and neural excitability in ways that worsen tinnitus for many people. Reducing intake during recovery often produces noticeable tinnitus improvement.

About 75% of post-concussion tinnitus cases improve significantly within 3-6 months. Complete resolution is common for first-time concussions. If tinnitus persists beyond 3 months, audiology evaluation and targeted treatment (sound therapy, cervical treatment, cognitive behavioral therapy) are effective at reducing severity. Should I see an audiologist for post-concussion tinnitus? See an audiologist if tinnitus persists beyond 4-6 weeks, if it is only in one ear, or if you notice hearing loss alongside the tinnitus. Audiological evaluation identifies whether there is measurable hearing change and guides treatment. Pulsatile tinnitus (rhythmic, heartbeat-synced) warrants earlier evaluation. Does post-concussion tinnitus mean I have hearing damage? Not necessarily. Most post-concussion tinnitus reflects central auditory processing disruption in the brain, not peripheral hearing damage in the ear. Hearing tests are often normal despite significant tinnitus after concussion. The brain is generating the sound, not the ears. This distinction matters because it means the cause is reversible as brain function recovers. References Kreuzer, P. M., et al. (2014). Trauma-associated tinnitus.
