Condensers are another common type of microphone, and are especially popular when it comes to recording music. The transducer inside of a condenser has an especially thin diaphragm that moves in relation to a metallic back plate. Because this backplate is electrically charged, incoming sound waves will cause the distance between it and the diaphragm to change and generate a signal we can measure.
Ribbon designs are among the earliest forms of microphone technology, having graced many classic radio broadcasts back in the day. The transducer consists of an incredibly thin ribbon of aluminum or other conductive material placed between the pole ends of a magnet, and any movement in that ribbon due to incoming sound waves will create a voltage.
Sound Wave is a stock motion graphics video that shows a visual image of a sound wave in motion, as sound is generated. This 1920x1080 (HD) video comes with an alpha channel and can be placed on top of background material or other composite elements. This background will enhance the sound of your video because it complements the design. Download this video today, and add it to your next film, project, or intro, presentation, or commercial.

In 2012 a study published in The Lancet Oncology showed the vast promise of high-intensity focused ultrasound (HIFU) for the treatment of prostate cancer. Usually surgeons remove the whole prostate, damaging the surrounding nerve and muscle tissue. About 15% of patients undergoing treatment experience urinary incontinence, and 70% lose the ability to get an erection. Of the 40 men who underwent treatment with HIFU, wherein surgeons burned off bits of cancerous tissue as small as a grain of rice, 90% could still get erect, and none became incontinent. Better still, a year later 95% showed no cancer.
Wave actions are somehow there - they unfold in a dungeon where dark tunnels keep the unknown and terrible monsters who are not averse to hunting you. The only thing that can help you navigate in space is sound. Sound will be your main guides to these cold gloomy labyrinths. An unusual world awaits you, which is interesting to explore and dive into it further and further, feeling like a pioneer.
If you book our music video package we will give you a Free complimentary upgrade to our special fx lighting package includes a bubble machine, green laser and sound reactive nightclub type lights that scan the dance floor at no extra charge!

Some venues with larger rooms require more speakers or sub woofers to properly maintain an adequate sound level. For events with guests of 150 or more or if your event is in a large ballroom with high ceilings this option is highly recommended!
The earliest practical recording technologies were entirely mechanical devices. These recorders typically used a large conical horn to collect and focus the physical air pressure of the sound waves produced by the human voice or musical instruments. A sensitive membrane or diaphragm, located at the apex of the cone, was connected to an articulated scriber or stylus, and as the changing air pressure moved the diaphragm back and forth, the stylus scratched or incised an analogue of the sound waves onto a moving recording medium, such as a roll of coated paper, or a cylinder or disc coated with a soft material such as wax or a soft metal.
The adoption of sound-on-film also helped movie-industry audio engineers to make rapid advances in the process we now know as "multi-tracking", by which multiple separately-recorded audio sources (such as voices, sound effects and background music) can be replayed simultaneously, mixed together, and synchronised with the action on film to create new 'blended' audio tracks of great sophistication and complexity. One of the best-known examples of a 'constructed' composite sound from that era is the famous "Tarzan yell" created for the series of Tarzan movies starring Johnny Weissmuller.
Although there have been numerous refinements to the technology, and other related technologies have been introduced (e.g. the electrostatic loudspeaker), the basic design and function of the dynamic loudspeaker has not changed substantially in 90 years, and it remains overwhelmingly the most common, sonically accurate and reliable means of converting electronic audio signals back into audible sound.
The fourth and current "phase", the "digital" era, has seen the most rapid, dramatic and far-reaching series of changes in the history of audio recording. In a period of fewer than 20 years, all previous recording technologies were rapidly superseded by digital sound encoding, and the Japanese electronics corporation Sony in the 1970s was instrumental with the first consumer (well-heeled) PCM encoder PCM-F1, introduced in 1981 -f1.htm. Unlike all previous technologies, which captured a continuous analogue of the sounds being recorded, digital recording captured sound by means of a very dense and rapid series of discrete samples of the sound. When played back through a digital-to-analogue converter, these audio samples are recombined to form a continuous flow of sound. The first all-digitally-recorded popular music album, Ry Cooder's Bop 'Til You Drop, was released in 1979, and from that point, digital sound recording and reproduction quickly became the new standard at every level, from the professional recording studio to the home hi-fi.
The digital audio file marked the end of one era in recording and the beginning of another. Digital files effectively eliminated the need to create or use a discrete, purpose-made physical recording medium (a disc, or a reel of tape, etc.) as the primary means of capturing, manufacturing and distributing commercial sound recordings. Concurrent with the development of these digital file formats, dramatic advances in home computing and the rapid expansion of the Internet mean that digital sound recordings can now be captured, processed, reproduced, distributed and stored entirely electronically, on a range of magnetic and optical recording media, and these can be distributed anywhere in the world, with no loss of fidelity, and crucially, without the need to first transfer these files to some form of permanent recording medium for shipment and sale.
The earliest method of sound recording and reproduction involved the live recording of a performance directly to a recording medium by an entirely mechanical process, often called "acoustical recording". In the standard procedure used until the mid-1920s, the sounds generated by the performance vibrated a diaphragm with a recording stylus connected to it while the stylus cut a groove into a soft recording medium rotating beneath it. To make this process as efficient as possible, the diaphragm was located at the apex of a hollow cone that served to collect and focus the acoustical energy, with the performers crowded around the other end. Recording balance was achieved empirically. A performer who recorded too strongly or not strongly enough would be moved away from or nearer to the mouth of the cone. The number and kind of instruments that could be recorded were limited. Brass instruments, which recorded well, often substituted instruments such as cellos and bass fiddles, which did not. In some early jazz recordings, a block of wood was used in place of the snare drum, which could easily overload the recording diaphragm.
In 1857, Édouard-Léon Scott de Martinville invented the phonautograph, the first device that could record sound waves as they passed through the air. It was intended only for visual study of the recording and could not play back the sound. The recording medium was a sheet of soot-coated paper wrapped around a rotating cylinder carried on a threaded rod. A stylus, attached to a diaphragm through a series of levers, traced a line through the soot, creating a graphic record of the motions of the diaphragm as it was minutely propelled back and forth by the audio-frequency variations in air pressure.
In the spring of 1877 another inventor, Charles Cros, suggested that the process could be reversed by using photoengraving to convert the traced line into a groove that would guide the stylus, causing the original stylus vibrations to be recreated, passed on to the linked diaphragm, and sent back into the air as sound. Edison's invention of the phonograph soon eclipsed this idea, and it was not until 1887 that yet another inventor, Emile Berliner, actually photoengraved a phonautograph recording into metal and played it back. 041b061a72
