Neon Lamp Traces Sound Waves

That's sound wave you see in the picture above. Here demonstrating how an acoustic lens focuses sound from a a horn, the wave was made visible with the device at left-an alluminium rod with a microphone and a neon lamp at the end. A small motor swings the rod in a wide arc, scanning the area. The microphone picks up the sound and turns it into electric current to fed the lamp. where ever the sound is strongest, the light is brightest, and the wave is traced out. A complete sound photo, such as this from Bell labs, takes 10 minutes exposure.

Latest invention In Sound : Flat Flexible Speakers that Produce a Clear Sound


 A loudspeaker, which is less than 0.25mm thick, is the latest invention in technologypresented by engineers from University of Warwick. The device is flexible and can be easily hung up a wall in an apartment or, due to its specific technique of producing sound, it can be used as a way of making clear public announcements in different places, such as, for example passenger terminals. Besides being extremely lightweight, this latest technological invention does not require huge investments. Slim and flexible, such speakers can be installed in ceiling tiles or inside vehicles.

Warwick Audio Technologies, is a spin-out company that says its device generates planar directional sound waves in public places. These waves project further than sound produced by usual speakers. Engineers dubbed their latest invention Flat, Flexible Loudspeaker (FFL). According to the company's CEO, Steve Couchman, the revolutionary speaker could completely replace the conventional speakers that are nowadays used in homes, cars and public places such as passenger terminals and shopping centers.

"Audio visual companies are investigating its use as point of sale posters for smart audio messaging and car manufacturers are particularly interested in it for its light weight and thinness," he said.
The flexible speaker works by transforming an electric signal into sound. In conventional speakers the signal is used to produce a varying magnetic field that vibrates a mechanical cone, thus making the sound. However, the technology behind the flexible speaker connects thin, conducting and insulating, materials that create a flexible laminate. When an electrical signal excites the laminate, it vibrates, so generating sound.

TIMELINE -- DEVELOPMENT OF FILM AND SOUND ON FILM


1870s -- Eadweard Muybridge -- Movement of a horse stop action photography on glass plates. Done with multiple cameras designed so that a horse's foot would trip each shutter.

1882 -- Frenchman Etienne-Jules Marey designed a camera to record 12 separate images on a single strip of film. In 1888 he designed the first flexible film.

1889 -- Eastman Kodak introduces celluoid flexible film base

1888 -- Thomas Alva Edison meets with Edweard Muybidge and purchases 90 of his plates to begin experimenting with moving pictures. His intention was to couple live action with the sound produced by his phonograph.

Late 1880s -- Edison commissions William Kennedy Laurie Dickson to build a film camera. Dickson develops the Kinetograph which coupled recorded images with phonographic sound. The final result in 1892, the peep show penny arcades which were first installed in 1894.
William Kennedy Laurie Dickson conducted many experiments with the Kinetograph. One of the earliest surviving experiments is his film of co-worker Fred Ott's "Sneeze":
         
1895 -- Louis and Auguste Lumiere present the first film projector -- the Cinematographe.

1896 -- Edison produces a film projector developed by Thomas Armat and C. Francis Jenkins and exploited by vaudeville peep show promoters Norman C. Raff and Frank R. Gammon. This projector was called the Vitascope.

April 1896 -- First public movie theatre -- the Theatre Robert Houdin -- operated by magician and photographer Georges Melies in Paris using a modified British projector developed initially by Robert William Paul. Meleis became known for developing the world's first "trick" photography with cut edits and disolves. 1902 he produced Jules Verne's A Trip To The Moon 14 minutes long and three times the length of any previous film. This also demonstrated Melies genius for editing with 30 separate scenes.

1902 -- 1926 : The era of the silent film while inventors including Edison sought to link sound mechanically with moving film images.
1904 -- Frenchman Eugene Lauste records sound onto a piece of photographic film

1907 -- 1913 various fim and sound inventions included the Vivaphone, Synchroscope, the Chronophone, the Cameraphone and the Cinephone. Edison produced the Kinetophone in 1913 -- a "Rube Goldberg" device of belts and pulleys and received boos for his efforts at Keith's Union Square theatre in New York City.

19teens -- Western Electric develops along with Lee DeForest (1906 Audion) a method or recording and reproducing sound electronically on disc. Western Electric Buought the rights to the use of the Audio for amplifying the phonographic sound.

1921 -- DeForest improves the method of recording sound on film and patents a new invention he calls the phonofilm.

September 1925 -- Warner Bros. contracts with the AT&T method of sound with film and releases its first sound with film pictures in 1926 using a system dubbed theVitaphone. Don Juan, released in 1926 was the first film to inlcude music on an amplified sound- track.

October 1927 -- The Jazz Singer featuring Al Jolson is released by Warner Bros. Not an immediate hit in New York, but it gained long-lasting fame when it moved into America's heartland. It was rebooked in 1928 in New York and grossed $100,000 a week.

May 1927 -- Fox Film Corporation works with a new AT&T development -- sound on film. Fox uses this system to produce newsreels which would play prior to feature films at theatres.The first big publicity coups was the flight of Charles Lindbergh across the Atlantic. Also memorable was the capturing of the explosion of the Hindenburg. These newsreel shorts became known as the Movietone News.

May 1928 -- the major film companies (Paramount, Loews/MGM, First National and United Artists) sign with AT&T to produce pictures with sound on film despite the introduction of a competing format developed by RCA.

End of 1920s -- only a few theatres in America's largest cities continued to maintain a house orchestra and organist.

September 1928 -- Warner Bros. releases The Singing Fool -- again starring Al Jolson. Tickets for the first night were $11.00. "Sonny Boy" and "There's a Rainbow 'Round My Shoulder" from the film became the first million selling record of the "talkie" era. The Singing Fool cost $200,000 to produce but drew an unprecedented $5,000,000.

Learn To Listen The Music


Usually the music is played while we clean the house or wash clothes. It is in the background, but we do not actually listen to it. To really enjoy 'good' music of any genre we must really listen to it. Sit down, have a cup of coffee or a drink of choice, and listen. You will be amazed at how enjoyable this can be.

Listen to music that might be new to you, or that you wished you could understand. Try a light opera, or perhaps an instrumental music. Do not think of anything else. This is a time to listen, enjoy and relax. You are going to try to develop a mental map of the music.

Understand that in musical composition, there are three main technical ideas:
-o- Repetition
-o- Variation
-o- New Melodies

Listen, and try to notice whether what you are hearing is the same as what you have previously heard in the same piece. Identify the elements:

Learn that the introduction, or beginning of a piece is always new. There is very often also something new very near the end. Locate passages that you find especially rewarding. Are these passages repetitions, variations, or new? If they are variations, can you realize what it was that was varied?5

Listen once more to the same passage. This time, pay attention to what brings the music to these passages. Listen to as many details as you can.
-o- Colors
-o- Balances
-o- Textures of the different sounds of which music is composed.

Try to isolate specific details:
-o- Rhythms, whether in the foreground or background, that seem to interact
-o- Short melodic figures, either in the principal melody
 -o- Accompaniment.


Listen again, narrowing your focus: listen only to the bass, if there is one. Notice things in the bass that seem alive, pregnant with meaning. Notice all the details you previously noticed by switching your attention from one to the other.

Develop your mental map of the characters, actors and energies that combine to create music. If these steps are correctly followed, the result will be a panoramic expansion of your musical experience, which may be likened to listening in color.

7 simple steps for connecting a single microphone and a pair of speakers


My dear students & friends -  here is the 7 simple steps for connecting a single  microphone and a pair of speakers.

STEP 1.   Install the two speakers, one on each side of the front of your audience. Aim the speakers so that the left speaker covers the left side of the audience and the right side speaker covers the right side of the audience. This is for mono use. If you choose stereo, you'll need two sound sources such as a left and right channel of music/sound. One microphone should always be hooked up mono.





STEP 2.  Place your single cardioid microphone on its stand where you plan to place the person speaking but never in front of the speakers. When you place the microphone in front of the speakers, your chances of producing feedback (that squealing sound) are greatly enhanced. A microphone placed behind the sound system has a much better chance of rejecting feedback. The cardioid microphon’s pick up pattern is directed away from the back of the mic and helps to reduce feedback as well.

STEP 3. Connect the microphone cable to your mixer/preamp at input one. You may have a "line" or "mic" switch above the volume knob or slider. Use the "mic" position. The "line" position is normally used for music sources such as a CD or Cassette player. If you have a gain control knob, (sometimes called trim) above the slider/ fader, fix it To get the proper input level.

STEP 4. Connect the preamplifier/mixer mono output to the mono input of your amplifier. If there is no mono input on your amplifier, you may use the left chanel of the amp to drive both speakers (assuming you have enough power in the amp) or "Y" the Left and Right inputs to the amplifier. This means that the mono out of the preamp is "Y" connected to both left and right amplifier inputs. Set the amplifier volume controls to minimum until we get a good level coming out of your preamp.



STEP 5.  Connect the output channels of your amplifier to the left and right speakers. Keep cables neat and taped down. They are easy to trip on and cause injury to someone.

STEP 6. Now that you're all connected, you can set levels. Take the mic and talk normally into it. Watch the meter on the preamplifier as you raise the slider (or fader) up slowly. Have your master control set at 3/4 or "7" as a good place to begin. Raise the input one control until you reach the maximum allowable setting on your meter. this would be "0" on a needle meter (VU Meter) or to the yellow light on an LED meter. If you get into the red, lower your gain setting on the "input gain" knob. Your ideal setting should be with your input one slider or knob at 3/4 or "7" for correct mixing board operation. Never run your input way down low and your master way up high. This will only overload your console and give you distorted sound.

STEP 7. When you've got your proper settings on the preamplifier, slowly turn your amplifier volume controls up until a good listening volume is achieved. If your mic goes into feedback, lower the volume or move the mic further away from the speakers.
