Accepted Answer

A) tinnitus. 
B) dynamic range. 
C) stereopsis. 
A) tinnitus. 
B) dynamic range.

Question 2

When a cello and a trombone play the same musical note what physical property of their sound is alike? What physical property of their sound is different?

Accepted Answer

When two instruments play the same note,this means that they are both producing the same fundamental frequency.In addition,this frequency will be accompanied on each instrument by a series of harmonic tones,each a multiple of the fundamental frequency.The differing tim- bres produced by each instrument result from the different relative amplitude of each harmonic frequency.The pleasing sound of string instruments reflects the greater contribution (higher amplitude)of their higher harmonic components.

Question 3

A) musical 
B) pure 
C) impure 
A) musical 
B) pure 
C) impure B

Question 7

A high-fidelity loudspeaker creates sound when a diaphragm in the shape of a flattened cone vibrates back and forth.The forward movement creates compression,and the backward move- ment creates refraction;together these movements create a complete sound pressure cycle.If the cone takes 10 ms to complete one cycle,what is the frequency of the sound being produced?
