(f)

At sites with background or ambient noise levels which are at, or in excess of, the applicable sound level limits set forth in table 1, the maximum allowable amplified sound level will be the greater of three dB(A-wt)/dB(C-wt) above the sound level limits set forth in table 1, or one dB(A-wt)/dB(C-wt) above the background or ambient noise level.
