| signal-to-noise ratio | <microscopy> Also sometimes used as an abbreviation for serial number, can be somewhat confusing in the case of electronic equipment. (05 Aug 1998) |
| structured noise | In radiology, the signals from anatomic structures which interfere with the detection of significant pathology. (05 Mar 2000) |
| noise | 1. Sound of any kind. "The heavens turn about in a most rapid motion without noise to us perceived." (Bacon) Noise is either a sound of too short a duration to be determined, like the report of a cannon; or else it is a confused mixture of many discordant sounds, like the rolling of thunder or the noise of the waves. Nevertheless, the difference between sound and noise is by no means precise. 2. Especially, loud, confused, or senseless sound; clamor; din. 3. Loud or continuous talk; general talk or discussion; rumor; report. "The noise goes." "What noise have we had about transplantation of diseases and transfusion of blood!" (T. Baker) "Soerates lived in Athens during the great plague which has made so much noise in all ages." (Spectator) 4. Music, in general; a concert; also, a company of musicians; a band. "The king has his noise of gypsies." (B. Jonson) Synonym: Cry, outcry, clamor, din, clatter, uproar. Origin: F. Noise noisy strife, quarrel, brawl, fr. L. Nausea seasickness, sickness, disgust. See Nausea. Source: Websters Dictionary (01 Mar 1998) |
| noise-induced deafness | A type of sensorineural deafness caused by prolonged exposure to loud sounds, e.g., jet engines. (05 Mar 2000) |
| noise, occupational | Noise present in occupational, industrial, and factory situations. (12 Dec 1998) |
| noise, transportation | Noise associated with transportation, particularly aircraft and automobiles. (12 Dec 1998) |
| optical noise | <microscopy> Image defects that become especially conspicuous when the image is enhanced. In video microscopy, includes hot spots, mottle, uneven illumination, etc. (05 Aug 1998) |
| British Thermal Unit | <unit> Unit of energy needed to raise one pound of water by one degree fahrenheit. It is equal to 252 calories or 1055 Joules. Acronym: BTU (13 Nov 1997) |
| differential thermal analysis | Technique by which phase transitions of chemical reactions can be followed by observation of the heat absorbed or liberated. (12 Dec 1998) |
| thermal | Pertaining to or characterised by heat. (18 Nov 1997) |
| thermal anaesthesia | Loss of temperature appreciation. (05 Mar 2000) |
| thermal barrier | <radiobiology> In magnetic mirror devices, this is a depression of electrostatic potential formed by enhancing ion loss in the region between the central cell and the positive potential plug. The thermal barrier significantly reduces the density requirements in the plug and lowers the overall power required to sustain the solenoidal plugging by thermally decoupling central cell electrons from the end plugs. (09 Oct 1997) |
| thermal burn | A burn caused by heat. (05 Mar 2000) |
| thermal capacity | <chemistry> The amount of energy required to raise the temperature of an object by one degree Celsius (or Kelvin), it is represented by the symbol C and is given in units of J/K. (09 Jan 1998) |
