Lavalier Microphone
A lavalier microphone or lavalier (also known as a lav, lapel mic, clip mic, body mic, collar mic, neck mic or personal mic) is a small microphone used for television, interview and other studio applications to allow hands-free operation. They are most commonly provided with small clips for attaching to collars, ties, or other clothing. The cord may be hidden by clothes and either run to a radio frequency transmitter kept in a pocket or clipped to a belt, or routed directly to the mixer or a recording device. These miniature microphones are often supplied with a choice of push-on grills of differing lengths that provide gentle high-frequency boost by forming a resonant cavity. A peak of approximately 6 dB at 6–8 kHz is considered beneficial for compensating loss of clarity when chest-mounted, as is a peak of a few decibels at 10–15 kHz when mounted in the hair above the forehead. This method of boosting high frequencies does not worsen noise-performance, as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lavalier Microphone On Shirt
A lavalier or lavaliere or lavalliere is an item of jewelry consisting of a pendant, sometimes with one stone, pendulous and centered from a necklace. The style was popularized by the Duchesse de la Vallière, a mistress of King Louis XIV of France. A lavalier can be recognized most for its drop, usually consisting of a stone and/or a chandelier pendant, which is attached directly to the chain, not by a Bail (jewelry), bail. According to Hans Nadelhoffer, ''Cartier: Jewelers Extraordinary'' (1984), p. 50: "Lavallière" is still the French name for a pussy bow. Later, the Fraternities and sororities in North America, American collegiate fraternity system ("greeks") adopted a lavalier which contained the fraternity letters as part of or within the pendant to symbolize involvement in an ongoing romantic relationship. Women receiving these pendants were called "dropped," but may later enter a long-term relationship resulting in becoming "pinned" (woman receiving the man's ...

Wax Cylinder
Phonograph cylinders (also referred to as Edison cylinders after its creator Thomas Edison) are the earliest commercial medium for recording and reproducing sound. Commonly known simply as "records" in their heyday (c. 1896–1916), a name which has been passed on to their disc-shaped successor, these hollow cylindrical objects have an audio recording engraved on the outside surface which can be reproduced when they are played on a mechanical cylinder phonograph. The first cylinders were wrapped with tin foil but the improved version made of wax was created a decade later, after which they were commercialized. In the 1910s, the competing disc record system triumphed in the marketplace to become the dominant commercial audio medium. Early development In December 1877, Thomas Edison and his team invented the phonograph using a thin sheet of tin foil wrapped around a hand-cranked, grooved metal cylinder. Tin foil was not a practical recording medium for either commercial or ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lavallière
A lavallière, also called a pussycat bow or pussybow, is a style of neckwear worn with women's and girls' blouses and bodices. It is a bow tied at the neck, which has been likened to those sometimes put on "pussy cats". History While bows at the neck had been worn since at least the 19th century; the term "pussy cat bow" took hold in the 20th century. It has been suggested that "There is always been something subtly subversive about the pussybow", and that it "evokes defiance". Kate Strasdin of Falmouth University says "Historically, it's associated with women who are starting to invade male spaces – the golf course, the workplace – and challenge traditional dress codes". The pussybow blouse is often paired with trousers. The lavallière in 19th century France The lavallière is a type of cravat similar to the bow tie that was popularly worn in the 19th century in France. It is of similar fashion to the bow tie, but has a larger knot and drooping ends. The length of the sca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Moleskin
Moleskin is a heavy cotton fabric, woven and then shorn to create a short, soft pile on one side. The feel and appearance of its nap is suede-like, less plush than velour and more like felt or chamois. The word is also used for clothing made from this fabric. Clothing made from moleskin is noted for its softness and durability. Some variants of the cloth are so densely woven as to be windproof. Its name is due to the soft brushed hand of the fabric, similar to mole fur. Though mole pelts have been used to make fur clothing, they are not referred to as "moleskin". Moleskin is also a term for soft, dense adhesive pads stuck to the skin to prevent blisters. Structure Moleskin is woven of carded cotton yarn in a dense weft-faced satin weave. The surface is napped or shorn to "produce a suede-like finish". Uses Moleskin fabric is commonly used to make trousers, also referred to as "moleskins", that are similar to jeans in terms of cut and construction. They similarly started a ...

Signal-to-noise Ratio
Signal-to-noise ratio (SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise. SNR is defined as the ratio of signal power to noise power, often expressed in decibels. A ratio higher than 1:1 (greater than 0 dB) indicates more signal than noise. SNR is an important parameter that affects the performance and quality of systems that process or transmit signals, such as communication systems, audio systems, radar systems, imaging systems, and data acquisition systems. A high SNR means that the signal is clear and easy to detect or interpret, while a low SNR means that the signal is corrupted or obscured by noise and may be difficult to distinguish or recover. SNR can be improved by various methods, such as increasing the signal strength, reducing the noise level, filtering out unwanted noise, or using error correction techniques. SNR also determines the maximum possible amount of data that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boom Operator (media)
A boom operator (or First Assistant Sound) is a core role in the sound department of a film production, who works with the production sound mixer and utility sound technician. The principal responsibility of the boom operator is microphone placement, usually using a boom pole (or "fishpole") with a microphone attached to the end (called a boom mic), their aim being to hold the microphone as close to the actors or action as possible without allowing the microphone or boom pole to enter the camera's frame. Invention of the boom mic The first noted instance of a prototype boom mic was on ''The Wild Party (1929 film), The Wild Party'' (1929). To allow Clara Bow to move freely on the set, director Dorothy Arzner had technicians rig a microphone onto a fishing rod. Another instance of a boom mic was on the set of ''Beggars of Life'' (1928) when director William A. Wellman wanted a tracking shot of two actors walking down a street, and the Production sound mixer, sound man refused, tell ...

Dictaphone
Dictaphone was an American company founded by Alexander Graham Bell that produced dictation machines. It is now a division of Nuance Communications, based in Burlington, Massachusetts. Although the name "Dictaphone" is a trademark, it has become genericized as a means to refer to any dictation machine. History The Volta Laboratory was established by Alexander Graham Bell in Washington, D.C. in 1881. When the Laboratory's sound-recording inventions were sufficiently developed with the assistance of Charles Sumner Tainter and others, Bell and his associates set up the Volta Graphophone Company, which later merged with the American Graphophone Company (founded in 1887) which itself later evolved into Columbia Records (founded as the Columbia Phonograph Company in 1889). The name "Dictaphone" was trademarked in 1907 by the Columbia Graphophone Company, which soon became the leading manufacturer of such devices.
