Sound is defined as " (a) Oscillation in pressure, stress, particle displacement, particle velocity, etc., propagated in a medium with internal forces (e.g., elastic or viscous), or the superposition of such propagated oscillation. (b) Auditory sensation evoked by the oscillation described in (a)." [ 2]
Surround sound. Surround sound is a technique for enriching the fidelity and depth of sound reproduction by using multiple audio channels from speakers that surround the listener ( surround channels ). Its first application was in movie theaters. Prior to surround sound, theater sound systems commonly had three screen channels of sound that ...
No speaker, monitor or hi-fi sound system, regardless of the design principle or cost, has a completely flat frequency response; all speakers color the sound to some degree. Monitor speakers are assumed to be as free as possible from coloration. While no rigid distinction exists between consumer speakers and studio monitors, manufacturers ...
7.1 surround sound is the common name for an eight-channel surround audio system commonly used in home theatre configurations. It adds two additional speakers to the more conventional six-channel ( 5.1) audio configuration. As with 5.1 surround sound, 7.1 surround sound positional audio uses the standard front left and right, center, and LFE ...
A loudspeaker (commonly referred to as a speaker or speaker driver) is an electroacoustic transducer [1]: 597 that converts an electrical audio signal into a corresponding sound. [2] A speaker system , also often simply referred to as a speaker or loudspeaker , comprises one or more such speaker drivers , an enclosure , and electrical ...
Unlike some other multichannel surround formats, its transmission channels do not carry speaker signals. Instead, they contain a speaker-independent representation of a sound field called B-format, which is then decoded to the listener's speaker setup. This extra step allows the producer to think in terms of source directions rather than ...
A PC speaker is a loudspeaker built into some IBM PC compatible computers. The first IBM Personal Computer, model 5150, employed a standard 2.25 inch magnetic driven (dynamic) speaker. [ 1] More recent computers use a tiny moving-iron or piezo speaker instead. [ 2] The speaker allows software and firmware to provide auditory feedback to a user ...
Hi-fi speakers are a key component of quality audio reproduction. High fidelity (often shortened to Hi-Fi or HiFi) is the high-quality reproduction of sound. [ 1] It is popular with audiophiles and home audio enthusiasts. Ideally, high-fidelity equipment has inaudible noise and distortion, and a flat (neutral, uncolored) frequency response ...
