Pitch and Loudness – Practice
1) Place the following sound waves in order of:
a) decreasing pitch: b) increasing volume:
2) Use the standard wave below to draw a sound wave that is:
a) higher in pitch:
b) lower in volume:
c) lower in volume and pitch:
d) higher in volume and lower in pitch:
3) A sound wave has a frequency of 1600Hz and an amplitude of 2cm.
a) If the sound is altered to have a pitch twice as high and it is 3 times as loud, how does this impact the frequency and amplitude?
b) What is the wavelength of the new sound wave?
1a) C, B, D, A
1b) A, B, D, C
2) See worked answer below
3a) pitch = 3200 Hz, amplitude = 6cm
