UNIT 7 & UNIT 8

Question 1

sound wave

Answer 1

pure tones when pressure changes

Question 2

vibration

Answer 2

= amplitude
times/sec the pressure changes

Question 3

frequency

Answer 3

number of cycles/sec of pressure changes

Question 4

additive synthesis technique

Answer 4

using pure tone with same frequency as complex and then adding pure tones with a frequency multiple of the fundamental (base)

Question 5

Steven’s magnitude estimation

Answer 5

increasing 10 dB double the sound’s loudness

Question 6

pitch

Answer 6

perceptual quality described as high or low

Question 7

tone height

Answer 7

increasing pitch, which increases tone’s fundamental frequency

Question 8

periodicity pitch

Answer 8

pitch perceived when fundamental frequency or other harmonics are removed

Question 9

timbre

Answer 9

harmonic structure of tone, same loudness pitch and duraction buit sound different

Question 10

aperiodic sounds

Answer 10

sound waves that do not repeat

Question 11
