Headset (audio)

A headset combines a headphone with a microphone. Headsets are made with either a single-earpiece (mono) or a double-earpiece (mono to both ears or stereo). Headsets provide the equivalent functionality of a telephone handset but with hands-free operation. They have many uses including in call centers and other telephone-intensive jobs and for anybody wishing to have both hands free during a telephone conversation.

Types of headset

Headsets are available in single-earpiece and double-earpiece designs. Single-earpiece headsets are known as monaural headsets. Double-earpiece headsets may support stereo sound (two slightly different channels of audio signal, one for each earpiece), or use the same audio channel for both ear-pieces.

Monaural headsets free up one ear, allowing interaction with others and awareness of surroundings. Telephone headsets are monaural, even for double-earpiece designs, because telephone offers only single-channel input and output.

For computer or other audio applications, where the sources offer two-channel output, stereo headsets are the norm; use of a headset instead of headphones allows use for communications (usually monaural) in addition to listening to stereo sources. Telephone headsets generally use 150-ohm loudspeakers with a narrower frequency range than those also used for entertainment. Stereo computer headsets, on the other hand, use 32-ohm speakers with a broader frequency range.

Headset (American band)

Headset was an American alternative rock band based in California, USA.

History

Formation

Originally known as Don Knotts Overdrive (DKO), this Hollywood-based performance art/rock ensemble began their career in 1993, consisting of Howard Hallis (today, an artist), Taylor Stacy (Magic Pacer, Erin Martin Band, Deletists, Reverz Engineers, Electromagnetic), Bobby Hecksher (Charles Brown Superstar, Magic Pacer, The Warlocks), Bob Mustachio (Magic Pacer, The Warlocks) and Daniel Meyer (Dashboard Prophets, Farflung).

Originally visually and shock-rock based, dressing as monsters, superheroes, animals, naked, etc., the LA party band released a 7" single in 1994 on Wrong Dimension Records.

In 1995, Hallis and Hecksher left the group as their full-length CD debut was released nationally.

Due to legal challenges from the actual Don Knotts, the group changed their moniker to The Headset.

In 1997, the group released "Twisted Steel, Leather Donut," which later appeared on the Orgazmo soundtrack album; a cover of the Devo song "Snowball" for the official tribute album We Are Not Devo, and a version of Frankie Goes to Hollywood's "Relax for Exene Cervenka's KPNK CD compilation soon followed.

Human back

The human back is the large posterior area of the human body, rising from the top of the buttocks to the back of the neck and the shoulders. It is the surface opposite to the chest, its height being defined by the vertebral column (commonly referred to as the spine or backbone) and its breadth being supported by the ribcage and shoulders. The spinal canal runs through the spine and provides nerves to the rest of the body.

Structure

The central feature of the human back is the vertebral column, specifically the length from the top of the thoracic vertebrae to the bottom of the lumbar vertebrae, which houses the spinal cord in its spinal canal, and which generally has some curvature that gives shape to the back. The ribcage extends from the spine at the top of the back (with the top of the ribcage corresponding to the T1 vertebra), more than halfway down the length of the back, leaving an area with less protection between the bottom of the ribcage and the hips. The width of the back at the top is defined by the scapula, the broad, flat bones of the shoulders.

Back (horse)

The back describes the area of horse anatomy where the saddle goes, and in popular usage extends to include the loin or lumbar region behind the thoracic vertebrae that also is crucial to a horse's weight-carrying ability. These two sections of the vertebral column beginning at the withers, the start of the thoracic vertebrae, and extend to the last lumbar vertebra. Because horses are ridden by humans, the strength and structure of the horse's back is critical to the animal's usefulness.

The thoracic vertebrae are the true "back" vertebral structures of the skeleton, providing the underlying support of the saddle, and the lumbar vertebrae of the loin provide the coupling that joins the back to the hindquarters. Integral to the back structure is the rib cage, which also provides support to the horse and rider. A complex design of bone, muscle, tendons and ligaments all work together to allow a horse to support the weight of a rider.

Anatomy of the back

The structure of the back varies from horse to horse and varies a great deal by breed, age and condition of the animal.
