Pop Filters
A pop filter, pop shield or pop screen is a noise protection filter for microphones, typically used in a recording studio. It serves to reduce or eliminate ''popping'' sounds caused by the mechanical impact of fast-moving air on the microphone from plosives during recorded speech and singing. Pop filters can also keep saliva off the microphone during recording. Background Popping sounds occur particularly in the pronunciation of aspirated plosives (such as the first 'p' in the English word "popping"). Other plosives can be 't', 'k', 'd', 'b', and 'g' sounds. The popping sound recorded by a microphone has two components: the high-frequency component, caused by air moving past the grille or other parts of the microphone body; and the low-frequency component, caused by air impacting the diaphragm. Mechanical and electrical saturation (e.g. clipping) can also play a role depending on the amount of headroom designed into these systems. Construction A typical pop filter is comp ...

Tights
Tights are a kind of cloth garment, most often sheathing the body from the waist to the toe tips with a tight fit, hence the name. They come in absolute opaque, opaque, sheer and fishnet styles — or a combination, such as the original concept of the American term pantyhose with sheer legs and opaque panty. Terminology and related clothing When made of fine silk, this hosiery was considered to be a stocking. When nylon fibers were developed and introduced in the 1940s, these stockings were referred to as nylons. When the separate legs were woven together with a panty that covered the lower torso up to the waist in a single, integrated format, the term pantyhose was coined, since it was a one piece construction of a panty with a pair of separate hose, one for each leg. This joining together eliminated any need for garters for holding up each separate leg covering. In American English, the difference between pantyhose and tights is determined in the weight of the yarn used and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Microphone
A microphone, colloquially called a mic or mike (), is a transducer that converts sound into an electrical signal. Microphones are used in many applications such as telephones, hearing aids, public address systems for concert halls and public events, motion picture production, live and recorded audio engineering, sound recording, two-way radios, megaphones, and radio and television broadcasting. They are also used in computers for recording voice, speech recognition, VoIP, and for other purposes such as ultrasonic sensors or knock sensors. Several types of microphone are used today, which employ different methods to convert the air pressure variations of a sound wave to an electrical signal. The most common are the dynamic microphone, which uses a coil of wire suspended in a magnetic field; the condenser microphone, which uses the vibrating diaphragm as a capacitor plate; and the contact microphone, which uses a crystal of piezoelectric material. Microphones typically n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saliva
Saliva (commonly referred to as spit) is an extracellular fluid produced and secreted by salivary glands in the mouth. In humans, saliva is around 99% water, plus electrolytes, mucus, white blood cells, epithelial cells (from which DNA can be extracted), enzymes (such as lipase and amylase), antimicrobial agents (such as secretory IgA, and lysozymes). The enzymes found in saliva are essential in beginning the process of digestion of dietary starches and fats. These enzymes also play a role in breaking down food particles entrapped within dental crevices, thus protecting teeth from bacterial decay. Saliva also performs a lubricating function, wetting food and permitting the initiation of swallowing, and protecting the oral mucosa from drying out. Various animal species have special uses for saliva that go beyond predigestion. Some swifts use their gummy saliva to build nests. ''Aerodramus'' nests form the basis of bird's nest soup. Cobras, vipers, and certain other membe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
De-essing
De-essing (also desibilizing) is any technique intended to reduce or eliminate the excessive prominence of sibilant consonants, such as the sounds normally represented in English by " s", "z", "ch", "j" and "sh", in recordings of the human voice. Sibilance lies in frequencies anywhere between 2 and 10 kHz, depending on the individual voice. Causes Excess sibilance can be caused by compression, microphone choice and technique, and even simply the way a person's mouth anatomy is shaped. Ess sound frequencies can be irritating to the ear, especially with earbuds or headphones, and interfere with an otherwise modulated and pleasant audio stream. Process of de-essing De-essing is a dynamic audio editing process, only working when the level of the signal in the sibilant range (the ess sound) exceeds a set threshold. De-essing temporarily reduces the level of high-frequency content in the signal when a sibilant ess sound is present. De-essing differs from equalization, which ...

Sibilant
Sibilants are fricative consonants of higher amplitude and pitch, made by directing a stream of air with the tongue towards the teeth. Examples of sibilants are the consonants at the beginning of the English words ''sip'', ''zip'', ''ship'', and ''genre''. The symbols in the International Phonetic Alphabet used to denote the sibilant sounds in these words are, respectively, . Sibilants have a characteristically intense sound, which accounts for their paralinguistic use in getting one's attention (e.g. calling someone using "psst!" or quieting someone using "shhhh!"). In the hissing sibilants and , the back of the tongue forms a narrow channel (is '' grooved'') to focus the stream of air more intensely, resulting in a high pitch. With the hushing sibilants (occasionally termed ''shibilants''), such as English , , , and , the tongue is flatter, and the resulting pitch lower. A broader category is stridents, which include more fricatives than sibilants such as uvulars. Because al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clothes Hanger
A clothes hanger, coat hanger, or coathanger, is a hanging device in the shape/contour of: * Human shoulders designed to facilitate the hanging of a coat, jacket, sweater, shirt, blouse or dress in a manner that prevents wrinkles, with a lower bar for the hanging of trousers or skirts. * Clamp for the hanging of trousers, skirts, or kilts. Both types can be combined in a single hanger. The clothing hanger was originally designed to allow people quick access to their clothing as well as designate an area, in their home, to keep their clothing in. It was also used to keep clothing dry or without a wrinkle. There are three basic types of clothes hangers. The first is the wire hanger, which has a simple loop of wire, most often steel, in a flattened triangle shape that continues into a hook at the top. The second is the wooden hanger, which consists of a flat piece of wood cut into a boomerang-like shape with the edges sanded down to prevent damage to the clothing, and a hoo ...

Embroidery Hoop
Embroidery hoops and frames are tools used to keep fabric taut while working embroidery or other forms of needlework. Hoops An embroidery hoop or (earlier) tambour frame consists of a pair of concentric circular or elliptical rings. The larger ring has a tightening device, usually in the form of a metal screw. The artisan repositions the hoop as needed when working over a large piece of fabric. Embroidery hoops come in various sizes and are generally small enough to control with one hand and rest in the lap. Hoops were originally made of wood, bone, or ivory;Christie, Grace: ''Embroidery and Tapestry Weaving'', London, John Hogg, 1912 modern hoops are made of wood or plastic.Reader's Digest ''Complete Guide to Needlework''. The Reader's Digest Association, Inc. (March 1992). , p. 10 Hoops may be attached to a table-top or floor stand when both hands must be free for sewing, as in making tambour lace.

Sieve
A sieve, fine mesh strainer, or sift, is a device for separating wanted elements from unwanted material or for controlling the particle size distribution of a sample, using a screen such as a woven mesh or net or perforated sheet material. The word ''sift'' derives from ''sieve''. In cooking, a sifter is used to separate and break up clumps in dry ingredients such as flour, as well as to aerate and combine them. A strainer (see Colander), meanwhile, is a form of sieve used to separate suspended solids from a liquid by filtration. Industrial strainer Some industrial strainers available are simplex basket strainers, duplex basket strainers, T-strainers and Y-strainers. Simple basket strainers are used to protect valuable or sensitive equipment in systems that are meant to be shut down temporarily. Some commonly used strainers are bell mouth strainers, foot valve strainers, basket strainers. Most processing industries (mainly pharmaceutical, coatings and liquid food indu ...

Stockings
Stockings (also known as hose, especially in a historical context) are close-fitting, variously elastic garments covering the leg from the foot up to the knee or possibly part or all of the thigh. Stockings vary in color, design, and transparency. Today, stockings are primarily worn for fashion and aesthetics, usually in association with mid-length or short skirts. History Historically, even though the word ''sock'' is at least as ancient in origin, what men normally wore were often referred to as stockings, probably especially when referring to longer hose. The word ''stock'' used to refer to the bottom "stump" part of the body, and by analogy the word was used to refer to the one-piece covering of the lower trunk and limbs of the 15th century—essentially tights consisting of the ''upper-stocks'' (later to be worn separately as knee breeches) and ''nether-stocks'' (later to be worn separately as ''stockings''). (See Hose.) Before the 1590s, stockings were made of woven cl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
