Fidelity definition is - the quality or state of being faithful. This provides the most flexibility for piece-by-piece upgrades and repairs. The NRC researchers knew that for their result to be credible within the scientific community and to have the most meaningful results, they had to eliminate bias, and blind testing was the only way to do so." What made you want to look up high fidelity? High fidelity (often shortened to hi-fi or hifi) is a term used by listeners, audiophiles and home audio enthusiasts to refer to high-quality reproduction of sound. Data gleaned from these blind tests is not accepted by some audiophile magazines such as Stereophile and The Absolute Sound in their evaluations of audio equipment. During the 1930s, Avery Fisher, an amateur violinist, began experimenting with audio design and acoustics. "[9], Doug Schneider, editor of the online Soundstage network, refuted this position with two editorials in 2009. High Fidelity is an attempt to minimize the effect of the electro-mechanical means necessary to the reproduction of music. Listening tests are used by hi-fi manufacturers, audiophile magazines and audio engineering researchers and scientists.

This is in contrast to the lower quality sound produced by inexpensive audio equipment, AM radio, or the inferior quality of sound reproduction that can be heard in recordings made until the late 1940s. In radio, sound recording, etc., an … 'Nip it in the butt' or 'Nip it in the bud'. One possible definition of many is that a high-fidelity audio system is one that reproduces the music with as little alteration as possible. Ideally, high-fidelity equipment has inaudible noise and distortion, and a flat (neutral, uncolored) frequency response within the human hearing range. In Healthcare Simulation, the degree to which a particular manikin can reproduce or mimic human physiology is known as fidelity. Wörterbuch der deutschen Sprache. A commonly used variant of this test is the ABX test. [8] Robert Harley of The Absolute Sound wrote, in 2008, that: "...blind listening tests fundamentally distort the listening process and are worthless in determining the audibility of a certain phenomenon. How do you use high fidelity in a sentence? It’s often used in the later usability evaluation to discover the potential issues that a web/app design may still exist. A monophonic power amplifier, which is called a monoblock, is often used for powering a subwoofer. In the 1980s, a number of audiophile magazines became available, offering reviews of components and articles on how to choose and test speakers, amplifiers and other components. Audiophiles paid attention to technical characteristics and bought individual components, such as separate turntables, radio tuners, preamplifiers, power amplifiers and loudspeakers. | Meaning, pronunciation, translations and examples Log In Dictionary Thesaurus Translator Grammar English … This period is regarded as the "Golden Age of Hi-Fi", when vacuum tube equipment manufacturers of the time produced many models considered endearing by modern audiophiles, and just before solid state (transistorized) equipment was introduced to the market, subsequently replacing tube equipment as the mainstream technology.
