Unit 6: Understanding the World Through Sound

what is the harmonic spectrum?

frequencies that are exact multiples of the amplitudes

what is the missing fundamental effect?

what will the brain hear when we take out specific vibrations of the fundamental and changing the timbre

• people hear the same pitch, our brain detects it by occurrence of temporal harmonics

• sound changes in properties, but pitch stays the same

what is the timbre?

psychological sensation that arises by the contribution of the harmonic components of a sound as a whole

what is the onset and offset of sound change in quality?

attack- how fast the sound’s beginning amplitude

decay- once a sound stops how slowly does the amplitude decrease
