Description of Pictures: "Hear My Voice": Alexander Graham Bell and the Origins of Recorded Sound
January 26, 2015 – October 25, 2015
Alexander Graham Bell is best remembered as the inventor of the telephone, but he was also instrumental in the development of sound recording at his Volta Laboratory in Washington, D.C. See documents, recordings, laboratory notes, and apparatus from the Volta Laboratory dating from the 1880s; learn about the early history of sound recording in the United States; and hear some of the earliest sound recordings ever made. The recordings are made audible through a 21st century sound recovery technique developed by Lawrence Berkeley Laboratory staff in partnership with the Library of Congress and the Museum.

Alexander Graham Bell and the Origins of Sound Recording:
In this gallery you can hear voices from the 1880s. Featured here is the only known recording of Alexander Graham Bell, created in 1885. "Hear my voice," Bell declares, from a time when listening to recorded sound was not today's commonplace, but an amazing new experience.
Bell's contemporary Thomas Edison had invented the phonograph in 1877, and, with it, a whole new kind of content-rich document: the sound recording. Never before had sounds been stored and then heard again.
A treasure trove of experimental recordings from Bell's laboratory, preserved but silent for over a century, survives at the Smithsonian. Thanks to a technology developed only a decade ago, the content of some of those records can now be heard. In the process, we have gained a new way to understand the past -- not just by looking at documents, but also by listening to them.
VOICE_150213_026.JPG: Replaying Sound: Thomas Edison (1847–1931)
Thomas Edison amazed the world in 1877 when he invented his "talking machine," the first instrument ever to record and play back sound.
The phonograph, as the machine came to be called, made indentations on tinfoil with a stylus. The stylus vibrated up and down as an attached diaphragm responded to sound waves -- like the phonautograph recording device developed twenty years before. Edison's breakthrough, conceived during work on telephones and telegraphs, reversed the phonautograph's recording process to allow for playback.
In April 1878 Edison licensed rights to sell the phonograph as a machine for office dictation. But sales were poor, and production soon stopped. Edison would not work on the phonograph again until 1888 when, in a frenzy of invention, he applied for seventeen patents on new sound technology.

Edison's first phonograph records were made from tinfoil indented by a stylus. The recordings quickly disintegrated with repeated playing, and the sound quality left much room for improvement.

VOICE_150213_045.JPG: Studying Sound: Alexander Graham Bell (1847–1922)
Alexander Graham Bell received the fundamental U.S. patent for the telephone and telephone system in 1876.
Bell's background was in hearing and speech, not electrical technologies. He came from a family of professional speech teachers, and his mother and his wife were both deaf. His early professional career focused on educating those with hearing and speech impairments.
In the early 1870s, while teaching in Boston, Bell had been studying acoustics at the Institute of Technology (now MIT). His experiments there, especially collaborating with a physician to construct a phonautograph based on the operation of the human ear, gave him the idea for the electric telephone and influenced his work on sound recording.

VOICE_150213_056.JPG: Picturing Sound: Édouard-Léon Scott de Martinville (1817–1879)
French typographer Édouard-Léon Scott de Martinville invented the phonautograph, a machine to make a visual record of sound waves traveling through the air. First patented in 1857 and revised repeatedly, his design would influence the direction of sound studies. The phonautograph was the first device to imitate the structure and function of the human ear.
Scott intended the phonautograph to transform sound into a kind of writing, as a means to preserve and recall it. The recordings were not intended for listening. They showed sound as wavy lines traced through a coating of soot on glass or paper. The machine created the lines with a vibrating stylus, set in motion by a flexible membrane that responded to sound waves -- similar to how an eardrum works. Although the machine never replaced stenography, the pictures of sound it produced aided scientific inquiries into the nature of sound.

VOICE_150213_084.JPG: "Hear My Voice"
This experimental wax disc contains the only confirmed recording of the voice of Alexander Graham Bell. He made it in 1885 to test with what clarity the recording could capture spoken numbers. Like Thomas Edison, Bell foresaw his recording system would be useful for business offices. On the recording, after several minutes of counting, Bell concludes:
"This record has been made by Alexander Graham Bell in the presence of Dr. Chichester A. Bell -- on the fifteenth of April, 1885, at the Volta Laboratory, 1221 Connecticut Ave., Washington, D.C. In witness whereof -- hear my voice. Alexander Graham Bell."

VOICE_150213_091.JPG: The Volta Laboratory Association
In 1879 Alexander Graham Bell moved to Washington, D.C., and established a laboratory with the help of instrument maker Charles Sumner Tainter. A year later they moved the lab to 1221 Connecticut Ave. N.W., where the recordings in this gallery were made.
Bell funded their research with ten thousand dollars received in 1880 from the French Volta Prize, awarded for his work on the telephone. His cousin Chichester Bell, a London chemistry professor, joined them, and the three young men formed the Volta Laboratory Association to share any profits their research might yield.
The association dissolved in 1885, and Chichester Bell returned to London. The collaboration eventually yielded sixteen sound patents, and Tainter continued work to bring their ideas to market.

VOICE_150213_102.JPG: Sound Experiments at the Volta Laboratory
Alexander Graham Bell, Charles Sumner Tainter, and Chichester Bell -- collectively the Volta Laboratory Associates -- conducted a wide range of sound experiments. Improving Thomas Edison's phonograph and phonograph record were their major goals.
They researched various techniques to record and play back sound, including photography and magnetic reproduction. They built machines for both cylinder and disc records and even a kind of recorder for use with waxed paper tape. They sought a durable recording medium and investigated materials of all sorts, alone and in combinations. And they explored methods to produce multiple copies of a single recording.
Their experiments led to commercial innovations -- most notably the wax cylinder record and the graphophone, a machine to record and play back cylinders.

VOICE_150213_125.JPG: Experimental Records from the Volta Laboratory
These are some of the earliest surviving sound recordings. They were made at the Volta Laboratory, most likely in 1884 and 1885.
The experimenters -- Alexander Graham Bell, Chichester Bell, and Charles Sumner Tainter -- imagined their invention would mainly serve as a business machine, for taking dictation or recording telephone conversations. So their goal was to find the best combination of materials and methods to record clear speech.
The individual speakers on these recordings are unidentified. Sometimes they quote Shakespeare, other times they count or repeat just a single word to test how clearly the word could be recorded. They frequently utter a trilled letter "r", which made a very distinct sound. Only one of these recordings was of music.
VOICE_150213_131.JPG: The Volta Laboratory and the Smithsonian
On October 30, 1881, the Volta Laboratory Association deposited a sealed box with the Smithsonian for safekeeping in case of a patent dispute.
The box contained equipment, recordings, and notes describing the original graphophone. The machine was a clear effort to improve on Thomas Edison's tinfoil phonograph. In fact, the device contained in the box was an Edison phonograph, altered with widened grooves and a cylinder coated in wax onto which a vibrating stylus could inscribe a message. For playback, the machine aimed a fine jet of air under high pressure at the record's grooves through a rubber hose (not present) attached to a fitting behind the cylinder.
From the web site at http://americanhistory.si.edu/documentsgallery/exhibitions/hear-my-voice/8.html :
On three occasions -- February 28, 1880; April 6, 1880; and October 30, 1881 -- the Volta Laboratory Associates delivered sealed tin boxes to the Smithsonian for safekeeping.
In addition to indicating Alexander Graham Bell's high regard for the Smithsonian's role in fostering science and technology, the deposit reflected his growing sensitivity to numerous challenges to his telephone patent. The confidential materials within these boxes could serve as evidence in case of a patent fight.
The first two boxes contained documentation for the photophone, a device to carry sound wirelessly on a light beam. Stowed in the third box was a copper recording and a new kind of sound recording and playback device, the graphophone.

The tin boxes remained in a Smithsonian vault until 1937, when they were opened in the presence of Bell relatives. In later years the Smithsonian collections came to include hundreds of other experimental recordings and apparatus from the Volta Laboratory, donated by Bell to the Smithsonian in 1914 and 1915. Volta Associate Charles Sumner Tainter's widow, Laura, donated his project notebooks.

VOICE_150213_189.JPG: The Volta Laboratory's Legacy:
The Volta Laboratory's commercial successes -- a way to engrave sound on a wax cylinder and a new machine to record cylinders and play them back called the graphophone -- transformed Thomas Edison's "talking machine" novelty into a workable technology. These successes spurred others -- including Edison, who resumed his phonograph work -- to enter the emerging industry of sound recording and playback.
Charles Sumner Tainter, one of the original Volta Laboratory Associates, continued to improve the original concepts for the graphophone after 1885 and stayed with the project to see the first machines into production in 1887.
The graphophone became a widely used dictation machine for business, eventually made and sold by the Dictaphone Corporation. As recorded-sound technologies branched into public and home entertainment, another part of the Volta Laboratory's business evolved indirectly into Columbia Records.

VOICE_150213_207.JPG: Recovering Sounds with IRENE:
The leading edge of preserving the content on endangered historic sound recordings is found in the world of high energy physics.
Using insights from his work on designing instruments for detecting subatomic particles, Carl Haber and his colleagues at the U.S. Department of Energy's Lawrence Berkeley National Laboratory developed a new method called IRENE beginning in 2003.
IRENE (Image, Reconstruct, Erase Noise, Etc.) consists of instruments for making high-resolution images of the surface of sound recordings without touching them and software for converting those images to digital sound files. The system can retrieve sound safely from historical recordings made on a wide variety of media regardless of their condition.
IRENE has evolved in collaboration with the Library of Congress, the National Endowment for the Humanities, and the Institute of Museum and Library Services.
VOICE_150213_211.JPG: Feel the Groove!
Sound is stored in the grooves of a recording. Cutting the record makes grooved patterns on the surface, and the patterns turn back into sound when a stylus runs along them.
These groove models represent magnified sections of four records displayed in this gallery. Compared with the original, the depth of the models' grooves are exaggerated, by a factor of give relative to the length and width, for emphasis.

VOICE_150213_227.JPG: Recovering Sounds to Preserve the Past:
The sounds you hear in this gallery are from rare experimental recordings made between 1881 and 1885. The records were considered unplayable until 2009.
The recovery of these sounds is the work of partners at Lawrence Berkeley National Laboratory -- scientists Carl Haber and Earl Cornell -- and the Library of Congress -- digital preservation specialist Peter Alyea. They have employed a new system designed to permit recordings, even broken or damaged ones, to be digitally reassembled and revived. Over the past decade, IRENE has recovered sound from recordings in a number of collections and a wide range of record formats and conditions.
This work offers some hope in improving the dire state of collections of early sound recordings around the world. A vast amount of our cultural heritage has been captured on fragile or obsolete recording media, and, without preservation, the content is inaccessible and in danger of being lost forever.
