Fire hose

A fire hose is a high-pressure hose that carries water or other fire retardant (such as foam) to a fire to extinguish it. Outdoors, it attaches either to a fire engine or a fire hydrant. Indoors, it can permanently attach to a building's standpipe or plumbing system.

The usual working pressure of a firehose can vary between 8 and 20 bar (800 and 2,000 kPa; 116 and 290 psi) while its bursting pressure can be up to 83 bar (8,300 kPa; 1,204 psi).

After use, a fire hose is usually hung to dry, because standing water that remains in a hose for a long time can deteriorate the material and render it unreliable or unusable. Therefore, the typical fire station often has a high structure to accommodate the length of a hose for such preventative maintenance.

On occasion, fire hoses are used for crowd control (see also water cannon), including most notably by Bull Connor in Alabama against civil rights protestors in 1964. While still a common practice in many countries, it is no longer used in the U.S.

Firehose (band)

Firehose (stylized as fIREHOSE) was an American alternative rock band consisting of Mike Watt (bass, vocals), Ed Crawford (guitar, vocals), and George Hurley (drums). They were initially active from 1986 to 1994, and reunited in 2012.

History

Firehose was formed in the spring of 1986 shortly after the accidental death of D. Boon brought an end to Watt and Hurley's previous band, Minutemen. Crawford, a then 21-year-old Ohio State student and Minutemen fan was invited up on the roof of the Camper Van Beethoven van in Columbus, Ohio. The members of Camper Van Beethoven told Crawford a false rumor that Watt and Hurley were auditioning guitarists for the band. Crawford, having found Watt's phone number in the phone book, called him up and expressed his desire to come out to California and play with them. Still mourning the loss of his friend Boon, Watt initially was not interested and had lost much of his desire to play music, however Crawford's persistence eventually paid off when he showed up unannounced in San Pedro and asked Watt for the chance to come over and play for him. Watt eventually agreed and the two met with Crawford "auditioning" for Watt by playing him The Who's, "I'm One" as well as a few Minutemen songs. Impressed with Crawford's passion and enthusiasm, Watt and Hurley agreed to give the inexperienced "kid" from Ohio a shot and the band was formed. Crawford quickly relocated to San Pedro where he became known as ed fROMOHIO and spent nine months sleeping under a desk in Watt's one bedroom apartment. The name of the band was taken from a short film of Bob Dylan doing "Subterranean Homesick Blues" as Watt thought it was funny when Dylan held up a cue card for the lyric that said "firehose".

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.
