Decibel, английский
- Unit to express differences of power level. it is used to express power loss in cables.
- Децибел d-b; d/b decimal-to-binary (conversion) десятично-двоичное преобразование
- A logarithmic measure for power ratios, applied e.g. to optical powers or to noise powers
- The unit in which the level, 4 of various acoustical quantities is expressed.
- A unit of measurement of the loudness of sound, used to compare different levels of sound. symbol db comment: normal conversation is at about 50db. very loud noise with a value of over 120db, e.g. that of aircraft engines, can cause pain.
- Децибел; дб decibel-log frequency characteristic логарифмическая частотная характеристика
- The unit of measurement of audio level. ten times the logarithm of the ratio of two power levels. twenty times the logarithm of the ratio of two voltages. standard abbreviations using decibels include: dbv (decibels relative to 1 volt), dbu (decibels relative to 0.775 volt), dbm (decibels relative to 1 milliwatt) and dba (decibels, a weighted).
- Logarithmic expression of a ratio of two amplitudes; abbreviation is db. db -20 log10 (a2/al), where al and a2 are amplitudes.
Decibel (db), английский
- A logarithmic ratio between two electrical signals or values. usually refers to power, but can also be used for voltage and current.
- A logarithmic comparison of power levels, defined as ten times the base-10 logarithm of the ratio of the two power levels. one-tenth of a bel.
Decibel, db (децибел, дб), английский
Десятичный логарифм отношения двух сигналов или двух значений, обычно относится к мощности, но также может относиться к напряжению или к току. если считается мощность, то логарифм умножается на 10, ток или напряжение
Decibelio, испанский
Decibels (db, db), английский
A unit used to express differences in electrical or acoustical signals including, for example, how noisy a motion picture camera or airplane is, or how much gain a dark location requires. formula: equal to 10 times the logarithm of the two levels. also see: gain; and white balance.

Met(eorological) service, английский
Meta, английский
- In a racetrack, a column or monument to mark a turn. metal-arc welding
- The greek word for ‘beyond’. in logical categorization, it means ‘at a higher level’, so oaks, ashes, beeches belong to the category ‘trees’, which in turn belongs to a meta-category, ‘plants’.
