COMD 5070 Fundamental Frequency FULLY SOLVED

COMD 5070 Fundamental FrequencyWhat is fundamental frequency? - correct answer *The lowest frequency *Reflects the rate at which the vocal folds are vibrating *Lowest rate of repetition; assumes there is repetition *Highest amplitude harmonic component of all the individual waves that add up together to make the voice spectrum Pitch is what kind of characteristic? - correct answer Perceptual not acoustic What is pitch influenced by? - correct answer *spectral properties of a sound *balance of different frequency components that are present in a complex wave that we hear *whether a sound is louder or softer may influence very slightly the pitch we perceive What kind of measure is fundamental frequency? - correct answer A physical measure; not a perceptual phenomenon How is fundamental frequency measured? - correct answer *Hz or cycles per second *can be derived by a computer; software calculates how many times the vocal folds oscillate Pitch and fundamental frequency are highly _________? Explain - correct answer correlated *as fundamental frequency goes up or down, the pitch we perceive goes up or down as well What is periodicity? - correct answer *the property of a signal that repeats or recurs over time. *individual cycle looks like any other;each looks like its neighbor *simple or complex it doesn't matter; if it repeats exactly then it is periodic *no variablity
