Study Questions #4: Complex Bell; Deconstructing Natural Sounds

Before you answer these questions, you should have reviewed the required reading for this session (including LINKS listed in the Class Schedule), and any LECTURE NOTES. Once you submit your answers, your grade will be recorded in your Student Gradefile and you will not be able to retake the quiz.

Please complete this set of Study Questions before the end of the next class session. However, the absolute deadline for completing them is 10:00 p.m. Friday, February 27.

A frequency in the spectrum of a sound which is in the Natural Harmonic Series is called a:
  
A frequency in the spectrum of a sound which is NOT in the Natural Harmonic Series is called a:
  
Another term for HARMONIC is:
  
Technically, HARMONIC and OVERTONE mean EXACTLY the same thing.
  
The THIRD harmonic in the NATURAL HARMONIC SERIES is equivalent to which OVERTONE:
  
The pattern of a vibrating body is called its:
  
A frequency (pitch or note) which is perceived by the listener which is significantly lower than the Fundamental in the Natural Harmonic Series is called a:
  
With natural percussive sounds (bells, drums, etc.), higher frequencies have a LONGER amplitude envelope that lower frequencies.
  
When you are synthesizing natural sounds with mutiple frequencies (i.e., the spectrum of the natural harmonic series), the respective amplitudes of the individual frequencies should:
  
When two periodic sounds occur simultaneously and one has a frequency that is slightly different than the other, an acoustic phenomonon will occur known as :
  
Another name for the effect which occurs as described in the question above is:
  
In the NATURAL HARMONIC SERIES, if the frequency of the FUNDAMENTAL is 440 Hz, what is the frequency of the 5th harmonic?
  
A percussive ENVELOPE usually has how many points (nodes)?
  
A woodwind ENVELOPE usually has how many points (nodes)?
  
When creating a patch in SYD, under normal conditions the duration of the Output Operator should equal the druation of the Amplitude Envelope.
  
When graphing (drawing by hand) an Amplitude Envelope, do you consider the starting position the FIRST POINT (NODE)?
  
Which best defines a "COMPLEX" sound (waveform):
