Questions: A certain sound is recorded by a microphone. The same microphone then detects a second sound, which is identical to the first one except that the amplitude of the pressure fluctuations is larger. In addition to the larger amplitude, what distinguishes the second sound from the first one? It is perceived as higher in pitch. It is perceived as louder. It has a higher frequency. It has a longer wavelength. A certain sound is recorded by a microphone. The same microphone then detects a second sound, which is identical to the first one except that it has twice the frequency. In addition to the higher frequency, what distinguishes the second sound from the first one? It is perceived as higher in pitch.

Solution

Solution Steps

Step 1: Analyze Part F

The question states that the second sound has a larger amplitude than the first sound. Amplitude correlates with loudness.

Step 2: Analyze Part G

The question states that the second sound has twice the frequency of the first sound. Frequency correlates with pitch. A higher frequency means a higher pitch.
