Hearing

Hearing, auditory perception, or audition is the ability to perceive sound by detecting vibrations, changes in the pressure of the surrounding medium through time, through an organ such as the ear. Sound may be heard through solid, liquid, or gaseous matter. It is one of the traditional five senses; partial or total inability to hear is called hearing loss.

In humans and other vertebrates, hearing is performed primarily by the auditory system: mechanical waves, known as vibrations are detected by the ear and transduced into nerve impulses that are perceived by the brain (primarily in the temporal lobe). Like touch, audition requires sensitivity to the movement of molecules in the world outside the organism. Both hearing and touch are types of mechanosensation.

Hearing mechanism

There are three main components of the human ear: the outer ear, the middle ear, and the inner ear.

Outer ear

The outer ear includes the pinna, the visible part of the ear, as well as the ear canal which terminates at the eardrum, also called the tympanic membrane. The pinna serves to focus sound waves through the ear canal toward the eardrum. Because of the asymmetrical character of the outer ear of most mammals, sound is filtered differently on its way into the ear depending on what vertical location it is coming from. This gives these animals the ability to localize sound vertically. The eardrum is an airtight membrane, and when sound waves arrive there, they cause it to vibrate following the waveform of the sound.

Havok (comics)

Havok (Alexander "Alex" Summers) is a fictional superhero appearing in American comic books published by Marvel Comics, commonly in association with the X-Men. He first appears in Uncanny X-Men No. 54 (March 1969), and was created by writer Arnold Drake and penciller Don Heck. Havok generates powerful “plasma blasts”, an ability he has had difficulty controlling. He is the son of Corsair, the younger brother of the X-Men's Cyclops, and the older brother of Vulcan. He often resents Cyclops' authoritarian attitude and reputation as a model X-Man.

In contrast, Havok and his longtime love interest Polaris have had a love-hate relationship with the team, often finding themselves roped into it. Both were also members of the 1990s-era Pentagon-sponsored mutant team X-Factor. After X-Factor disbanded, Havok starred in Mutant X, a series in which he explored a strange alternate reality. He has since returned to the X-Men, later taking over his father's role as leader of the Starjammers to bring Vulcan's reign over the Shi'ar to an end.
