Normal ear drum. A perforated eardrum (tympanic membrane perforation) is a prick in the eardrum. It can be caused by infection (otitis media), trauma, overpressure (loud noise), inappropriate ear clearing, and changes in middle ear pressure. An otoscope can be used to view the eardrum to diagnose a perforation. Perforations may heal naturally ...
A strain is a type of acute injury that occurs to the muscle or tendon. Similar to sprains, it can vary in severity, from a stretching of the muscle or tendon to a complete tear of the tendon from the muscle. Some of the most common places that strains occur are in the foot, back of the leg (hamstring), or back. [2]
In severe cases, middle ear hemorrhage or tympanic membrane rupture can result. [16] Tympanic membrane rupture: disruption of the eardrum. This can be caused by a blow to the ear, blast injury, barotrauma, or direct penetration of the tympanic membrane by an object entering the ear. [5]
When a person has a shock wave, not only is the eardrum ruptured, but also has ossicular discontinuities. The explosion or blast if powerful can cause traumatic brain injury. As a result, a person could have an auditory processing disability. Lung injures can develop as well as some injuries to the viscera. [8]
Generally, the muscle or tendon overstretches and is placed under more physical stress than it can withstand. [1] Strains commonly result in a partial or complete tear of a tendon or muscle, or they can be severe in the form of a complete tendon rupture. Strains most commonly occur in the foot, leg, or back.

Caitlin Clark left the Fever's game against NY on June 2 in what people thought was an ear injury. On Friday, she confirmed she ruptured her eardrum.
When external sound contacts the eardrum, the ossicles vibrate. This vibration can be amplified depending on the volume of the sound. When sound approaches over 70 decibels, the tensor tympani muscle contracts to assist in stabilizing the ossicles and reduce their vibration, which reduces the perceived volume of sound.
In the anatomy of humans and various other tetrapods, the eardrum, also called the tympanic membrane or myringa, is a thin, cone-shaped membrane that separates the external ear from the middle ear. Its function is to transmit changes in pressure of sound from the air to the ossicles inside the middle ear, and thence to the oval window in the ...
