Table B.2.
Mean A-weighted sound level, Loudness, Sharpness, and Partial Loudness characteristics of each operating condition under 31 dB(A) (night) and 39 dB(A) (day) background noise. Conditions at the top four rows are found in Part 2, while the rest are found in Part 1. Metrics calculated from stimuli after outdoor-to-indoor propagation filtering and at the listener position.
