Required attenuation of aircraft noise in buildings in the light of data from the Chopin Airport monitoring

The minimum attenuations of aircraft noise required by the Polish Standards concerning acoustic insulation and noise levels inside buildings have been compared. Data from the noise monitoring system of the Chopin Airport were used. The minimum attenuation required by PN-B-02151-02:1987 differs from that required by PN-B-02151-3:2015-10. The highest required attenuation occurs when taking into account the maximum sound level L_Amax of aircraft noise. The requirements related to L_Amax are 2.0 to 7.8 dB higher than those associated with the equivalent sound level L_Aeq. If the number of flight operations at night reaches the allowed maximum number of forty, the requirements related to L_Aeq may be decisive. The requirements connected with L_Aeq according to PN-B-02151-02:1987 are 0.6 to 2.6 dB higher than coming from PN-B-02151-3:2015-10.
