d) An Audio Signal Generator to generate sine waveform at variable frequency & amplitude.
e) The Sound Level Meter is placed at a dist5ance in front of the microphone and the Amplitude varied. Thus the Sound Level in DB V/s the amplitude can be plotted.
f) A Cardboard of 1m diameters with markings at 300 intervals can be made at your end. The loud speaker is placed at the center & the sound level meter at the periphery at 300 markings. A plot of dB variation w.r.t. the angular position can be drawn.
