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.

History

News division

The GMA News division traces its origin from the Republic Broadcasting System, established by Robert Stewart in 1959. Programming of its radio station, DZBB depended on mostly news reports. The station covered the eruption of Mt. Hibok-Hibok in 1951 and the election and death of the Former President Ramon Magsaysay. While RBS Channel 7 was established in 1961, it was in the 1970s that GMA became one of the most-watched television news source in the country. In 1983, Channel 7 was the first to break the news of Ninoy Aquino's death and later would be the only television station to broadcast his funeral. The channel also became the first station to broadcast the Ramos-Enrile break-away that led to the People Power Revolution (otherwise known as EDSA Revolution).

Sleeping at Last

Sleeping at Last is an alternative rock musical project led by singer-songwriter and multi-instrumentalist Ryan O'Neal. The project initially began in Wheaton, Illinois as a three-piece band with Ryan O'Neal as the lead singer and guitarist, his brother Chad O'Neal as the drummer, and Dan Perdue as the bassist. The band independently recorded their debut album, Capture in 2000, which they used to attract the attention of Smashing Pumpkins frontman Billy Corgan, who helped them get signed to a major record label Interscope Records. The band released their first and only major label album, Ghosts in 2003, before going independent again and releasing Keep No Score in 2006, and Storyboards in 2009.

In the years following the release of their first four albums, both Chad O'Neal and Purdue would both leave the band to pursue other interests. Ryan O'Neal chose to retain the use of the band's name for his solo work from that point on, but opted to focus on single songs and short EPs than any further traditional albums.

Crash Course

Crash Course (also known as Driving Academy) is a 1988 made for television teen film directed by Oz Scott.

Plot

Crash Course centers on a group of high schoolers in a driver’s education class; many for the second or third time. The recently divorced teacher, super-passive Larry Pearl, is on thin ice with the football fanatic principal, Principal Paulson, who is being pressured by the district superintendent to raise driver’s education completion rates or lose his coveted football program. With this in mind, Principal Paulson and his assistant, with a secret desire for his job, Abner Frasier, hire an outside driver’s education instructor with a very tough reputation, Edna Savage, aka E.W. Savage, who quickly takes control of the class.

The plot focuses mostly on the students and their interactions with their teachers and each other. In the beginning, Rico is the loner with just a few friends, Chadley is the bookish nerd with few friends who longs to be cool and also longs to be a part of Vanessa’s life who is the young, friendly and attractive girl who had to fake her mother’s signature on her driver’s education permission slip. Kichi is the hip-hop Asian kid who often raps what he has to say and constantly flirts with Maria, the rich foreign girl who thinks that the right-of-way on the roadways always goes to (insert awesomely fake foreign Latino accent) “my father’s limo”. Finally you have stereotypical football meathead J.J., who needs to pass his English exam to keep his eligibility and constantly asks out and gets rejected by Alice, the tomboy whose father owns “Santini & Son” Concrete Company. Alice is portrayed as being the “son” her father wanted.
