The tensor tympani is meant to pull the tympanic membrane inward, increasing tension of the tympanic membrane. It's like a calming mechanism that's in place in order to stabilize volume and respond to noise fluctuations, that also provides inner ear protection from loud sounds. It also helps ventilate the inner ear through the Eustachian Tube.
In many people with hyperacusis, an increased activity develops in the tensor tympani muscle in the middle ear as part of the startle response to some sounds. This lowered reflex threshold for tensor tympani contraction is activated by the perception/anticipation of loud sound, and is called tonic tensor tympani syndrome (TTTS). In some people ...
Hyperacusis is an increased sensitivity to sound and a low tolerance for environmental noise. Definitions of hyperacusis can vary significantly; it often revolves around damage to or dysfunction of the stapes bone, stapedius muscle or tensor tympani ().

Timpani produce inharmonic overtones, but are constructed and tuned to produce near-harmonic overtones to an implied missing fundamental. Hit in the usual way (half to three-quarters the distance from the center to the rim), the fundamental note of a timpani is very weak in relation to its second through fifth "harmonic" overtones.

According to Malbari, getting all of those vaccines out of the way before piercing a baby's ears protects against infections like hepatitis B, a rare but serious complication that can come from ...
Facing the inner ear, the medial wall (or labyrinthic wall, labyrinthine wall) is vertical, and has the oval window and round window, the promontory, and the prominence of the facial canal. Facing the outer ear , the lateral wall (or membranous wall ), is formed mainly by the tympanic membrane , partly by the ring of bone into which this ...
Prolonged inflammation leads to middle ear swelling, ulceration, perforation, and attempts at repair with granulation tissue and polyps. This can worsen discharge and inflammation, potentially developing into CSOM, often associated with cholesteatoma. Symptoms may include ear discharge or pus seen only on examination. Hearing loss is common.
