Computer Music (MUSC 216)
Quiz:  Acoustics Terms

Before you try to answer these questions, you should have reviewed the assigned reading at Principles of Acoustics: What Is Sound? 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.

Sound waves actually proprogate through the air as:
What is the approximate speed of sound through dry air:
A distinct and clearly audible repition of a sound is called:
Multiple reflections of a sound such that you cannot clearly hear them individually is called:
The lowest frequency of sound that can generally be discerned (heard) by the human ear is approximately:
The highest frequency of sound that can generally be discerned (heard) by the human ear is approximately:
Amplitude based on the loudest a sound can be without overloading the equipment:
Amplitude based on measuring the loudness of a sound in relationship to the loudness of another sound:
In this class, how will we generally consider amplitude:
A musical sound is really a composite of many component tones called:
For the most part, quivalent to the loudness of a sound:
Equivalent to the “pitch” of a sound (for example, a high or low sound):
A type of digital noise. Frequencies higher than one-half the sampling rate falsely appear as lower frequencies:
Two respective amplitudes are added together and produce an overall louder sound.:
The consequence of changing air pressure over time:
The amplitude of one sound is subtracted from the amplitude of another sound:
A sound represented graphically on paper or digitally on a computer:
No discernible repetitive wave pattern; RANDOM amplitude and frequency:
The ‘quality’ of the sound: piano, clarinet, violin, etc:
A type of digital noise. The amplitude of a sample exceeds the ability of the hardware to faithfully reproduce it (the sample exceeds the quantization range):
A type of amplitude modulation resulting from two waves of slightly different frequency interfering with each other:
Refers to the number of CYCLES per second in a periodic waveform:
44,100 Hz:
The point in a CYCLE where a wave begins:
The graphic representation of the Harmonic Series of a pitched sound:
