1. Sounds with different spectra necessarily have different pitch (true or false) _False?_
2. Sounds with different pitch necessarily have different spectra (true or false) _True?_
3. Different musical instruments that are playing the same note still sound different
according to their _spectra? or harmonic?_
4A. Why should we think that harmonics higher than 5000 Hz would not contribute to pitch
perception?
4B. Why do they contribute anyway? 5A. On the following plot, draw harmonics of a complex sound with fundamental of
500 Hz to illustrate which harmonics would be resolved and unresolved.
5B. Draw indices (1, 2, 3, etc) on the harmonics.
5C. Draw a boundary between resolved and unresolved portions of the spectrum. 10. Draw three waveforms: a 50-Hz pure tone, a 54-Hz pure tone, and a mixture of both tones as
they would combine in an auditory filter.
