MULTIPLE CHOICE ANSWERS - SOUND

Phon has nothing to do with this question.

Intensity is measured in Wm^-2

So at the microphone, the intensity is the same.
And the reading on the oscilliscope which is attached to the microphone would vary with the frequency because the microphone is more sensitive to 3kHz than it is to 1kHz

hold up isnt fidelity when the graph is higher above 0??

I said A for question 10 as the question stated that the intensity levels had to stay the same. Just seemed like the logical answer.

i think it should be B, it said they were the same intensity, but u had to refer the the graph, and the microphone was more sensitive to the higher frequency sound, so its amplitude had to be higher than the other sound.
