Daily indicators:

2023-03-26

L24 = N/A 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 = 45.7 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 = N/A dBLAdaydaily 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. = N/A dBLAeveningevening 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 = N/A dBLAmaxmaximum 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 = N/A dBLAminminimum 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 = 51.0 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 = 33.5 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.
