Cellist Yo-Yo Ma plays a note at 250 Hz. A studio technician performs an
analysis of the frequency spectrum and reports that she measured the SIL of its peaks (those
of the frequency spectrum): 63 dB at 250 Hz, 58 dB at 500 Hz, 56 dB at 750 Hz, and 51 dB at
1000 Hz.
Assuming that only the peaks in the frequency spectrum matter (they dominate everything
else), what is the total SIL in dB?
