Description of Pictures: America's Listening
October 19, 2018 – TBA
America's Listening tells the story of recorded sound and five of the innovations that contributed to how we consume music and movies today. Artifacts on view include Thomas Edison’s phonograph, Alexander Graham Bell’s graphophone, Emile Berliner’s gramophone, Ray Dolby’s noise reduction system, and Apple’s iPod.

SIAHAL_200925_015.JPG: Apple's iTunes
MP3 and other digital players used sound files, not records or tapes. In 2001, Apple introduced iTunes, an online platform that sold digital songs for just 99 cents apiece -- which licensed and paid royalty fees for the music it sold -- made purchasing so easy that it helped reduce illegal file sharing. Apple, pushed by cofounder Steve Jobs, then developed a user-friendly digital player, the iPod.
Listening Anytime
Ever-smaller players with ever-larger capacities for tunes and, later, podcasts, made it possible to listen anytime -- even all day. As many workplaces transformed into cubicle farms or as workers moved to communal spaces, players with earbuds provided a sense of privacy. And user-created playlists became valued expressions of individual identity.

SIAHAL_200925_077.JPG: Edison's Talking Machine
In 1877 Thomas Edison invented the first device to ever record and play back sound. Soundwaves captured by a mouthpiece caused a stylus attached to a diaphragm to move up and down, making indentations on a sheet of tinfoil wrapped around a rotating drum. In playback, the stylus traced those indentations, causing the diaphragm to recreate a recognizable version of the original sound.
SIAHAL_200925_079.JPG: Listening in Public
Thomas Edison's "talking machine" was a public sensation. It -- not the light bulb -- earned him the moniker "Wizard of Menlo Park." Americans first read about the device in the papers, but soon witnessed it for themselves for public demonstrations around the country. They were in awe. This machine could capture a sound and transport it to the future.
SIAHAL_200925_085.JPG: Sales of Thomas Edison's tinfoil phonograph were poor -- its recordings were fragile and short-lived -- and he abandoned it. Nearly a decade later, spurred by competition from Alexander Graham Bell, Edison made multiple improvements and introduced new machines that found popular appeal. The Edison Home Phonograph, first manufactured in 1896, played individually prerecorded wax cylinders.
SIAHAL_200925_096.JPG: One of Volta Lab's prototype graphaphones, 1886. The wax cylinder could record about five minutes of dictation, or two or three short business letters.
SIAHAL_200925_101.JPG: Bell's Graphophone
Alexander Graham Bell and his associated at the Volta Laboratory set out to best Thomas Edison's original phonograph. They were convinced of the profit-making potential of an improved device -- especially one that could capture more clearly the speaking voice. They originated wax cylinder records, and developed a machine to record and play them, the graphophone.
SIAHAL_200925_104.JPG: Listening at Work
Inventors and investors saw recorded sound not as a source of entertainment, but as a tool for business. And new corporations looked to "talking machines" to increase efficiencies in their ever-growing managerial departments. But these devices enabled new workplace hierarchies, with male managers upstairs recording dictation that female typists downstairs played back and put to paper.

SIAHAL_200925_115.JPG: Berliner's Gramophone
In 1887 German immigrant Emile Berliner patented the first in a series of inventions that would result in the first commercially successful disc record and a machine to play it: the gramophone. He also created a process to mass-produce multiple copies from a single master recording. Flat discs were longer playing, easier to store, and more durable than cylinders.

SIAHAL_200925_138.JPG: Commercial versions of the gramophone were a hit with the public, who thrilled at the expanding repertoire of popular music and classical celebrity performers available on mass-produced discs.

Gateway to Culture
To be an inventor, you have to be willing to live with a sense of uncertainty.

SIAHAL_200925_150.JPG: Dolby's Noise Reduction System
Recording on magnetic tape introduced unwanted noise or "hiss" to the sound; the noise only accumulated as the original production tapes were duplicated, then played. In 1965, Ray Dolby invented electronic circuitry that removed unwanted noise by processing the audio signal. Recording studios quickly adopted Dolby's system, and makers of cassette tape players soon followed.
SIAHAL_200925_152.JPG: Listening on the Move
Cassette tapes were small and easily transported. Small, lightweight cassette players, whether handheld or tucked into fanny packs, were a boon to commuters and joggers. Transistor radios had made music portable in the 1950s, but cassettes let the listener be the DJ by selecting or creating their own "mix" tapes.
SIAHAL_200925_154.JPG: Ray Dolby's first product, the model A301, used a circuit design that reduced tape noise by compressing and expanding audio signals, 1965.

SIAHAL_200925_170.JPG: In 1984, Sony added a miniaturized version of Ray Dolby's noise reduction system to its Walkman Pro. The feature soon became widely available; without it, hiss was especially noticeable because listeners' headphones blocked many distracting sounds.

2020 photos: Well, that was a year, wasn't it? The COVID-19 pandemic cut off most events here in DC after March 11.
The child president's handling of the pandemic was a series of disastrous missteps and lies, encouraging his minions to not wear masks and dramatically increasing infections and deaths here.The BLM protests started in June, made all the worse by the child president's inability to have any empathy for anyone other than himself. Then of course he tried to steal the election in November. What a year!
Equipment this year: I continued to use my Fuji XS-1 cameras but, depending on the event, I also used a Nikon D7000.
The farthest distance I traveled after that was about 40 miles. I only visited sites in four states -- Maryland, Virginia, West Virginia and DC. That was the least amount of travel I had done since 1995.
Number of photos taken this year: about 246,000, the fewest number of photos I had taken in any year since 2007.
