Suppose a flutist plays a 523-Hz C note with first harmonic displacement amplitude A 1 = 100 nm. From Figure 17.21b read, by proportion, the displacement amplitudes of harmonics 2 through 7. Take these as the values, A 2 through A 7 in the Fourier analysis of the sound and assume B 1 = B 2 = ⋯ = B 7 = 0 . Construct a graph of the waveform of the sound. Your waveform will not look exactly like the flute waveform in Figure 17.20b because you simplify by ignoring cosine terms; nevertheless, it produces the same sensation to human hearing.
