The ubiquity of modern headphones could perhaps be attributed to the Sony Walkmanwhich debuted in and almost immediately became a pop culture icon. As the first affordable, portable music player, the Walkman became such an prominent characteristic of the young urban professional that it was even featured on the cover of The Yuppie Handbook.
But of course, the history of headphones dates back further than the s. Like many commercial electronics, modern headphones and stereo sound originated, in part, in the military. Photo from Electrophone advertisement British Telephone Systems In the s, a British company called Electrophone created a system allowing their customers to connect into live feeds of performances at theaters and opera houses across London.
Subscribers to the service could listen to the performance through a pair of massive earphones that connected below the chin, held by a long rod. The form and craftsmanship of these early headphones make them a sort of remote, audio equivalent of opera glasses.
It was revolutionary, and even offered a sort of primitive stereo sound. Ina particularly memorable letter written in purple ink on blue and pink paper came from Utah native Nathaniel Baldwin, whose missive arrived with a pair of prototype telephone headsets offered for military testing.
More telephones were requested for testing and Baldwin obliged at his own expense. The Navy offered Baldwin some suggestions for a a few tweaks, which he promptly incorporated into a new design that, while still clunky, was comfortable enough for everyday use. After producing a few dozen headphones, the head harness was further improved as its design was reduced to only two leather-covered, adjustable wire rods attached at each end to a receiver that supposedly contained a mile of copper wire.
Baldwin, however, refused on the grounds that it was a trivial innovation. In order to increase production, the Navy wanted to move Baldwin out of his Utah kitchen and into much larger East Coast facility.
Another manufacturer, the Wireless Specialty Apparatus Co. The agreement with Wireless Specialty came with one enormous caveat: The next big innovation in headphone design came after the second World War, with the onset of stereophonics and the popular commercialization of the technology.
The only problem was that there were no commercially available headphones that were compatible with his new phonograph. They were all made for communication or warplanes. Koss talked with an audio engineer about this and they quickly rigged up a pair of makeshift prototype headphones.
The design was refined built from two vacuum-formed brown plastic cups containing three-inch speakers protected by a perforated, light plastic cover and foam ear pads. These were connected by a bent metal rod and the Koss SP-3 headphones were born.
Music lovers embraced the stereophonic headphones due to their enhanced sound quality, which was made possible by the use of different signals in each ear that could closely approximate the sounds of a concert hall.
The design was well received when it debuted at a hi-fi trade show in Milwaukee in and was almost immediately copied by other manufacturers, standardizing the design of headphones around the world for years to come.
As a result, any deviation from the assigned course results in the most beautiful ping-pong stereophony.ONE. But, you may say, we asked you to speak about women and fiction--what, has that got to do with a room of one's own? I will try to explain. So far though, there’s been no sign of Iran breaking into any sealed nuclear equipment or otherwise violating the nuclear deal, which the United Nations continues to monitor.
Today under the deal, Iran can maintain a stockpile of only kilograms ( pounds) of low-enriched uranium, compared to the , kilograms (, pounds) of higher-enriched uranium it once had.
Nations may enter a transition zone—economically, socially, and politically—where the probability of moving in a democratic direction increases or decreases. I believe that this is the most exciting prophecy in the entire Bible. We have absolute proof that the United States can be discovered in the Bible.
Daniel spake and said, I saw in my vision by night, and, behold, the four winds of the heaven strove upon the great sea. And four great beasts came up.
