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.

Martyn (surname)

Martyn, or Martin is the surname of one of The Tribes of Galway, Ireland.

Family history

The Martyn family were one of a group of fourteen families of mixed descent who became the premier merchant and political families in the town of Galway during the late medieval and early modern eras. They traded with Scotland, England, Wales, France, Spain, and Portugal. Many were dispossessed by the Irish Confederate Wars and the subsequent Cromwellian conquest.

The family have been based in Co. Galway, Ireland, since the mid-14th century but have many cadet branches in the U.K., Canada, USA, France, Hungary, and several other countries. Most of these branches were emigrated during and in the aftermath of the Wild Geese and Great Famine eras.

Many branches of the family use the spelling Martin. As Martin is the most common spelling for bearers of the name regardless of descent, the form Martyn is used to distinguish all of this kindred from other thus surnamed but unrelated. Martin, Martyn and its variants can be considered some of the most common names in the Western world - such as Smith, Jones, Baker, Wilson. It is not always the case that any two bearers of the name are related, even distantly.
