Many individuals can voluntarily create a low rumbling or roaring sound within their ears. This internal sound is a curious phenomenon, often stumbled upon by chance, and many are unaware others share this unique ability.
What is the Roaring Sound?
This internal roaring sound is scientifically known as a voluntary tensor tympani contraction. It is also a type of myogenic tinnitus. Myogenic refers to sound originating from muscle activity, while tinnitus describes the perception of sound when no external sound is present. This self-generated sound is not a symptom of an external ear condition but a direct result of an individual’s action.
The sound is described as a low-frequency rumble, similar to distant thunder, strong wind, or a deep roar. It can be sustained for several seconds. Unlike other forms of tinnitus that can be distracting or indicative of an underlying issue, this voluntary sound is entirely under individual control.
How You Create the Sound
This sound involves a tiny middle ear muscle called the tensor tympani. This muscle is situated in a bony canal above the auditory tube. Its attachment point is the malleus, one of the three small bones in the middle ear that transmit sound vibrations to the inner ear.
When the tensor tympani muscle contracts, it pulls on the malleus. This action tenses the eardrum (tympanic membrane). Increased eardrum tension produces vibrations perceived as the low rumbling sound. This muscular action is similar to how a drumhead vibrates differently when its tension is altered. The sound is felt and heard internally because vibrations are generated within the ear.
Individuals often discover this ability through actions that naturally engage the tensor tympani, such as yawning, clenching their jaw, or flexing certain neck muscles. Over time, some learn to isolate and intentionally contract this muscle without these broader movements. This learned control allows voluntary sound production.
Why Not Everyone Can Do It
While the tensor tympani muscle is present in every human ear, the ability to voluntarily contract it varies among individuals. This is similar to how some people can voluntarily wiggle their ears or flare their nostrils, while others cannot. The difference often lies in conscious control over specific muscles.
Some individuals may have greater awareness of internal bodily sensations (proprioception), allowing them to identify and manipulate this muscle more readily. Subtle anatomical or neurological differences might also influence the ease of control. For many, the muscle may only activate reflexively, such as during a yawn, without conscious command. It is a harmless variation in human muscular control and awareness.
When to Consult a Professional
The ability to voluntarily create a roaring sound in your ears is generally benign and not a cause for concern. It is a normal, uncommon physiological function. However, distinguish this voluntary action from other types of involuntary, persistent ear noises or tinnitus.
If you experience constant, involuntary sounds in your ears (roaring, ringing, buzzing, etc.), especially if in one ear, or accompanied by ear pain, dizziness, vertigo, or hearing loss, consult a medical professional. These symptoms could indicate an underlying ear condition, nerve issue, or other health concern requiring evaluation. The voluntary sound, by contrast, is entirely within your control and ceases when you stop it.
