What is the difference between pitch perception and frequency measurement? - CORRECT
ANSWER - pitch is subjective to the listener
frequency is objective and can be measured
, How do waveforms differ as frequency goes up or down? - CORRECT ANSWER - higher
frequency wavelengths appear closer together with more frequency over a period of time than
lower frequencies
