  Lden = 64.5 dB Information Lden (day-evening-night noise level) noise index related to noise discomfort during whole day-evening-night period – according to Ordinance No. 6 from 26th of June 2006 from MH and MОEW for environmental noise indexes.

  Lnight = 55.1 dB InformationLnight (night noise level) noise index related to sleep disturbance during the night – according to Ordinance No. 6 from 26th of June 2006 from MH and MОEW for environmental noise indexes.

  Lday = 56.5 dB Information Lday (day noise level) noise index related to noise discomfort during day period – according to Ordinance No. 6 from 26th of June 2006 from MH and MОEW for environmental noise indexes.

  Lev. = N/A dB Information Levening (evening noise level) noise index related to noise discomfort during evening period – according to Ordinance No. 6 from 26th of June 2006 from MH and MОEW for environmental noise indexes.

  LAmax = 73.7 dB Information LAmax (maximum A-weighted noise level in dB(А)) This is the maximum value of current A-weighted noise level for certain time period – according to Ordinance No. 6 from 26th of June 2006 from MH and MОEW for environmental noise indexes.

  LAmin = 46.6 dB Information LAmin (minimum A-weighted noise level in dB(А)) This is the minimum value of current A-weighted noise level for certain time period – according to Ordinance No. 6 from 26th of June 2006 from MH and MОEW for environmental noise indexes.

  LAF10 = N/A dBLAF10The level of noise along a curve and which has exceeded 10% of the measurement time (T).
The parameter is used as a measure of the noise from the main measured (released) source.


  LAF90 = N/A dBLAF90The noise level in a curve which is exceeded for 90% of the time of measurement (T).
The parameter is used as an indicator of the ambient (background) noise.
