The steady state noise source limits are:

•   daytime (0700 to 1800 hours):               background + 5 dB(A) = 35 + 5 = 40 dB(A) LA10,adj,T;
•   evening (1800 to 2200 hours):               background + 5 dB(A) = 34 + 5 = 39 dB(A) LA10,adj,T;
•   night-time (2200 to 0700 hours):            background + 3 dB(A) = 26 + 3 = 29 dB(A) LA10,adj,T.
