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.
