A student is listening to a pure tone from a loudspeaker connected to a signal generator in a laboratory.
If the settings on the generator are kept constant but the student moves closer to the loudspeaker, describe the change in the sound heard.
State the effect on the sound heard if: (i) the amplitude of the wave is decreased. (ii) the frequency of the wave is decreased.
Explain how the sound wave is transmitted through the air from the loudspeaker to the student's ear, referring to the motion of air particles.
State the approximate range of frequencies that a healthy human ear can detect:
