Определение near-field в Английский Язык Английский Язык словарь
- In radio-frequency electromagnetic technology, the region within about half a wavelength from an electrically small antennaCharles Capps, “Near-field or Far Field,” EDN, August 16, 2001, pp. 95-102.. More specifically it is the region within the radiansphereWheeler, H.A.; "The Radiansphere around a Small Antenna"; Proceedings of the IRE Aug. 1959, Volume: 47 Issue: 8 pp: 1325 - 1331. 10.1109/JRPROC.1959.287198
- In physical acoustics, the region of space within a distance a fraction of a wavelength from a sound source. Accordingly, the outer boundary of the near-field region is closer for high-pitched sound than for low-pitched sound
- In loudspeaker acoustics, referring to a region where the intensity of direct, unreflected sound from the source (such as a loudspeaker) is significantly dominant over any indirect or reflected sound.Brungart Douglas S. and Rabinowitz William R.; "Auditory Localization in the Near-Field"; The Third International Conference on Auditory Display, November 1996
- Pertains to that range of listening distances in which the sounds reaching the ears are predominantly direct The opposite of "Far Field"
- That part of the sound field where the sound level varies from point to point because of the radiation pattern of the source
- The area that is very close to the transducer where the Inverse Square Law does not apply For speakers it is within a few feet of the diaphragm For microphones it is usually only a few inches This term is often erroneously used in place of Close Field when describing monitoring scenarios
- The area up to one foot from the sound source
- The region of an electromagnetic field comprising two components, the reactive Rayleigh region immediately surrounding the antenna and a radiating near field or Fresnel component which exists when the major dimension of the antenna, D, is large compared with the wavelength, l , of transmission
