Burgas Municipality, Territorial Directorate Osvobojdenie

Name of the location: Burgas Municipality, Territorial Directorate Osvobojdenie

Address of the location: Burgas, Complex "Slaveikov"

The beginning of the noise monitoring: November 2010г.

Noise categorization: Location with predominantly impact of noise from road traffic, as well as accidental overflying airplanes, departing from the main routes (Warning: changed situation in the summer of 2013. - with regard to the new defined ATC routes for landing / takeoff / test flights).

Excerpt from the Official Strategic noise map for the region – with mapped loop "Road Traffic - conflict values for L24 > 65 dB(A), as well as loop for „Airline loop actual before Summer 2013”. – for LAmax > 85 dB(A):


Daily indicators:



  L24 = 54.7 dBL2424-hour noise level, which is an indicator of the noise associated with discomfort (defined according to the ”Law for protection against environmental noise”)

  Lnight = 47.7 dBLAnightnight noise level is the A-weighted equivalent noise level averaged over a long period of time, relative to all the night periods in a year, as specified in standard ISO 1996-2:1987

Defined period "night period: (according to the Regulation No 6 of 26 June 2006 for" performance of noise in the environment "): 23- 07 h


  Lday = 51.6 dBInformationLAdaydaily noise level is the A-weighted equivalent noise level averaged over a long period of time, relative to all the day periods during the year, as specified in the standard BDS ISO 1996-2: 1987;

Defined period "day period" (according to Regulation No 6 of 26 June 2006 on "indicators of environmental noise"): 07-19 h.


  Lev. = 51.9 dBInformationLAeveningevening level of noise is the A-weighted equivalent noise level averaged over a long period of time, relative to all the evening periods in a year, as specified in standard ISO 1996-2: 1987;

Defined period "evening period: (according to the Regulation No 6 of 26 June 2006 for" performance of noise in the environment "): 19 – 23 h.


  LAmax = 84.8 dBInformationLAmaxmaximum A-weighted sound level in decibels [dB (A)].
This is the maximum value of the current A-weighted noise level for a given time interval.


  LAmin = 35.8 dBInformationLAminminimum A-weighted sound level in decibels [dB (A)].
This is the minimum value of the current A-weighted noise level for a given time interval.


  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.
