"Ear infections can interfere with sound transmission, causing a ringing sensation in the ear," Lewis says. "Infections cause inflammation and fluid buildup, which disturb the auditory system ...
The tensor tympani is a muscle within the middle ear, located in the bony canal above the bony part of the auditory tube, and connects to the malleus bone. Its role is to dampen loud sounds, such as those produced from chewing, shouting, or thunder.
When TTTS occurs, the middle ear is contracting involuntarily, which produces an audible sensation called the middle ear myoclonus. When the tensor tympani muscle experiences a spasm without the provocation of loud sounds, it's called the acoustic reflex, which is apart of a normal auditory system.
In some cases, tinnitus is generated by muscle spasms around the middle ear. [50] Spontaneous otoacoustic emissions (SOAEs)—faint high-frequency tones that are produced in the inner ear and can be measured in the ear canal with a sensitive microphone—may also cause tinnitus. [14]
For example, very curvy ear canals, narrow ear canals, or surgical ears are more prone to earwax buildup. When wax builds up, it causes muffled hearing, tinnitus, or aural fullness (plugged-up ...

Middle ear myoclonus occurs in the muscles of the middle ear. These muscles may include the tensor tympani and stapedius muscles. It can involve the muscles surrounding the Eustachian tube, which include the tensor veli palatini, levator veli palatini, and salpingopharyngeus. Those affected describe it as a thumping sound or sensation in the ear.
The acoustic reflex (also known as the stapedius reflex, [1] stapedial reflex, [2] auditory reflex, [3] middle-ear-muscle reflex (MEM reflex, MEMR), [4] attenuation reflex, [5] cochleostapedial reflex [6] or intra-aural reflex [6]) is an involuntary muscle contraction that occurs in the middle ear in response to loud sound stimuli or when the person starts to vocalize.
