A whooshing sound in the ear, particularly when chewing, is a common experience. This internal sound can be perplexing. Understanding its nature and potential origins can help individuals determine if medical attention is warranted. This article explores the characteristics of this phenomenon and its connections to the body’s anatomy and physiological processes.
Understanding the Whooshing Sound
The whooshing sound heard in the ear is often described as rhythmic or pulsating, similar to the sound of wind or blood flow. This internal sound can be distinct from external noises, and some individuals liken it to hearing their own heartbeat. The close anatomical relationship between the ear and the jaw plays a significant role in why chewing can make these internal sounds more noticeable.
Chewing involves the movement of muscles and joints located near the ear. The temporomandibular joint (TMJ), which connects the jawbone to the skull, sits just in front of the ear. This proximity means that movements or sounds from the jaw can be transmitted to the auditory system, making internal noises more apparent.
Common Reasons for the Sound
Several factors can contribute to a whooshing sound in the ear when chewing, each involving distinct physiological mechanisms. Understanding these common reasons provides insight into how the body’s systems can interact to produce such a perceived sound.
Temporomandibular joint (TMJ) dysfunction is a frequent cause. Issues with this jaw joint can transmit sounds directly to the ear. The TMJ shares muscles and nerves with the middle ear, and problems like misalignment or muscle tension can result in sounds perceived as whooshing or clicking. Jaw movement, such as during chewing, can alter muscle tension and influence the perception of these sounds.
Eustachian tube dysfunction (ETD) is another common reason. This occurs when the tubes connecting the middle ear to the back of the throat do not open or close properly. Normally, these tubes open when yawning, swallowing, or chewing to balance air pressure and drain fluid. When they malfunction, pressure changes can occur, leading to sensations like fullness, crackling, or amplification of internal body sounds, including chewing. In some cases, a patulous Eustachian tube, which stays open, can cause individuals to hear their own breathing, voice, and chewing sounds more loudly.
Vascular causes, often manifesting as pulsatile tinnitus, are characterized by a rhythmic whooshing sound that synchronizes with one’s heartbeat. This sound arises from changes in blood flow through vessels near the ear. Conditions such as high blood pressure, narrowed blood vessels, or increased blood flow from anemia can create turbulent flow that the ear perceives as a whoosh. Chewing can momentarily affect blood pressure and blood flow dynamics, potentially making this rhythmic sound more pronounced.
Muscle spasms of tiny muscles within or around the ear, such as the tensor tympani or stapedius, can also create internal noises. These muscles usually dampen loud sounds and reduce internal body noises like chewing. However, when they spasm, they can produce thumping, clicking, or whooshing sensations. These involuntary contractions can sometimes be triggered by actions like chewing or stress.
A buildup of earwax or the presence of foreign objects in the ear canal can also contribute to the perception of internal sounds. Such blockages can amplify the normal sounds of the body, including those generated during chewing, by preventing external sounds from masking them. Removing the blockage often resolves the issue.
When Professional Medical Advice is Needed
While a whooshing sound in the ear, especially when associated with chewing, can often be benign, certain indicators suggest that professional medical evaluation is advisable. Consult a healthcare provider if the sound becomes persistent, worsens over time, or significantly impacts daily activities.
It is particularly important to consult a healthcare provider if the whooshing sound is accompanied by other symptoms. These symptoms can include pain in the ear or jaw, dizziness, changes in hearing, facial numbness, or vision disturbances. If the sound is heard only in one ear, it also warrants medical attention.
A medical professional will typically begin by taking a detailed history of your symptoms and conducting a physical examination of the ear, head, and neck. Depending on the initial findings, further diagnostic tests, such as imaging studies, may be recommended to identify any underlying conditions.
Addressing and Managing the Sound
The approach to addressing and managing a whooshing sound in the ear that occurs with chewing depends directly on its underlying cause. A medical professional identifies this cause, and personalized treatment plans are often necessary to alleviate the symptom.
For issues related to temporomandibular joint (TMJ) dysfunction, conservative treatments are often recommended. These may include specific jaw exercises, stress reduction techniques, and the use of bite guards, especially at night, to prevent teeth grinding or clenching. Addressing the mechanical stresses on the jaw joint can help reduce the transmission of sounds to the ear.
In cases of Eustachian tube dysfunction, methods aimed at equalizing pressure in the middle ear can be beneficial. Simple actions like yawning, swallowing, or chewing gum can help open the tubes and relieve pressure. Nasal decongestants may also be suggested to reduce swelling and improve tube function, particularly if the dysfunction is linked to allergies or colds.
When vascular causes, such as pulsatile tinnitus, are identified, treatment requires medical intervention tailored to the specific condition. This could involve medication to manage blood pressure or, in some instances, procedures or surgery to address issues with blood vessels. A specialist determines the appropriate course of action.
For muscle spasms causing internal ear noises, relaxation techniques can be helpful in reducing the frequency or intensity of spasms. A healthcare provider might consider specific medications to help relax the involved muscles. General self-care measures, such as avoiding loud noises, managing stress levels, and maintaining adequate hydration, can also contribute to overall ear health.
