Question

A student is using a sound machine to produce the sound waves presented in the

data table above. How could the student manipulate the sounds to make them match
in pitch but make sound wave #1 louder than sound wave #2?

Answer 1

• adjust the frequencies of the sound waves to be the same
• adjust the amplitudes of the sound waves so that of #1 is higher

Step-by-step explanation:

The sound waves shown in the table have sound wave #1 at a higher pitch (frequency) and lower amplitude than sound wave #2. To make them have the desired relationship, the pitches of the two waves must be adjusted to be the same, and the relative amplitudes altered so that #1 is higher.

There are any number of possibilities here. They include, raising the frequency of #2 to that of #1, decreasing the frequency of #1 to that of #2, or adjusting both to a common frequency different from either one.

Likewise, possibilities for adjusting the loudness included raising the amplitude of #1 so it is greater than #2, reducing the amplitude of #2 so it is less than #1, or adjusting both so #1 is higher and #2 is lower than some middle amplitude.
