Pitch and Loudness – Practice

Questions:

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?
