The Early Years of the Acoustic Phonograph Its Developmental Origins and Fall from Favor 1877-1929
THE EARLY YEARS OF THE ACOUSTIC PHONOGRAPH ITS DEVELOPMENTAL ORIGINS AND FALL FROM FAVOR 1877-1929 by CARL R. MC QUEARY A SENIOR THESIS IN HISTORICAL AMERICAN TECHNOLOGIES Submitted to the General Studies Committee of the College of Arts and Sciences of Texas Tech University in Partial Fulfillment of the Requirements for the Degree of BACHELOR OF GENERAL STUDIES Approved Accepted Director of General Studies March, 1990 0^ Ac T 3> ^"^^ DEDICATION No. 2) This thesis would not have been possible without the love and support of my wife Laura, who has continued to love me even when I had phonograph parts scattered through out the house. Thanks also to my loving parents, who have always been there for me. The Early Years of the Acoustic Phonograph Its developmental origins and fall from favor 1877-1929 "Mary had a little lamb, its fleece was white as snov^. And everywhere that Mary went, the lamb was sure to go." With the recitation of a child's nursery rhyme, thirty-year- old Thomas Alva Edison ushered in a bright new age--the age of recorded sound. Edison's successful reproduction and recording of the human voice was the end result of countless hours of work on his part and represented the culmination of mankind's attempts, over thousands of years, to capture and reproduce the sounds and rhythms of his own vocal utterances as well as those of his environment. Although the industry that Edison spawned continues to this day, the phonograph is much changed, and little resembles the simple acoustical marvel that Edison created. -

Warburton, John Henry. (2010). Picture Radio
! ∀# ∃ !∃%& ∋ ! (()(∗( Picture Radio: Will pictures, with the change to digital, transform radio? John Henry Warburton Master of Philosophy Southampton Solent University Faculty of Media, Arts and Society July 2010 Tutor Mike Richards 3 of 3 Picture Radio: Will pictures, with the change to digital, transform radio? By John Henry Warburton Abstract This work looking at radio over the last 80 years and digital radio today will consider picture radio, one way that the recently introduced DAB1 terrestrial digital radio could be used. Chapter one considers the radio history including early picture radio and television, plus shows how radio has come from the crystal set, with one pair of headphones, to the mains powered wireless with built in speakers. These radios became the main family entertainment in the home until television takes over that role in the mid 1950s. Then radio changed to a portable medium with the coming of transistor radios, to become the personal entertainment medium it is today. Chapter two and three considers the new terrestrial digital mediums of DAB and DRM2 plus how it works, what it is capable of plus a look at some of the other digital radio platforms. Chapter four examines how sound is perceived by the listener and that radio broadcasters will need to understand the relationship between sound and vision. We receive sound and then make pictures in the mind but to make sense of sound we need codes to know what it is and make sense of it. Chapter five will critically examine the issues of commercial success in radio and where pictures could help improve the radio experience as there are some things that radio is restricted to as a sound only medium. -

The Lab Notebook
Thomas Edison National Historical Park National Park Service U.S. Department of the Interior The Lab Notebook Upcoming Exhibits Will Focus on the Origins of Recorded Sound A new exhibit is coming soon to Building 5 that highlights the work of Thomas Edison’s predecessors in the effort to record sound. The exhibit, accompanied by a detailed web presentation, will explore the work of two French scientists who were pioneers in the field of acoustics. In 1857 Edouard-Léon Scott de Martinville invented what he called the phonautograph, a device that traced an image of speech on a glass coated with lampblack, producing a phonautogram. He later changed the recording apparatus to a rotating cylinder and joined with instrument makers to com- mercialize the device. A second Frenchman, Charles Cros, drew inspiration from the telephone and its pair of diaphragms—one that received the speaker’s voice and the second that reconstituted it for the listener. Cros suggested a means of driving a second diaphragm from the tracings of a phonauto- gram, thereby reproducing previously-recorded sound waves. In other words, he conceived of playing back recorded sound. His device was called a paléophone, although he never built one. Despite that, today the French celebrate Cros as the inventor of sound reproduction. Three replicas that will be on display. From left: Scott’s phonautograph, an Edison disc phonograph, and Edison’s 1877 phonograph.

EXP-26 Open Frame CD Player
EXP-26 Open Frame CD Player Topics: Diode Laser, Detection of Light, CD Control System, CD Structure, Computer Control The most widespread laser applications are unambiguously the optical data storage systems such as CD, DVD and nowadays Blue-Ray disc (BD). The CD was originally designed for storage and playing back music and was later extended to the CD-ROM for computer storage. Most optical drives operate on the principle of detecting changes in the intensity of light that is reflected by the media surface. The data information is printed as so-called pits onto the reflective surface of the media. The limitation of the storage capacity is the wave length of the laser light. Light of a shorter wavelength can be focused better thus allowing higher storage density. Within this course the data detection, the control loop for the reading laser head and other components of an optical drive will be demonstrated using the open frame CD player. The optical technique to read data remains the same regardless of whether a CD, a DVD or a BD is used. Examples of Investigations: Reading assembly: A laser beam of 780 nm wavelength is focused on the CD by means of lenses L1 and L2. The spot size on the reflective layer is about 0.6 µm. The light returning from the CD is reflected by the polarizing beam splitter cube (BC) due to the action of the quarter wave plate (QWP) and is imaged on the position sensitive sensor (PSD). Detection of pits: Once the laser beam hits a pit, a change in reflected light intensity occurs due to partial scattering and destructive interference between the incoming and outgoing laser beam.
