1000, 5000, lowest, highest - answer-hearing is more sensitive at some frequencies -lowest thresholds are from _______ to _______ Hz -thresholds are much higher for ______ and for ______ frequency sounds 12, nonlinear, bigger - answer-there are _______ semitones in 1 octave -each semitone is a _________ step- each step upward is _______ than the last (about 5.9%) -no semitones are physically identical in Hz, but they SOUND equal in step size, because our human perception of sound is nonli...

Can jitter and shimmer co-occur? - answer-yes; you won't find one without the other How do waveforms differ as frequency goes up or down? - answer-higher frequency wavelengths appear closer together with more frequency over a period of time than lower frequencies How does a complex periodic sound change when the fundamental is removed or muted? - answer-when removed, the timbre (quality) differs, but the pitch is perceived as the same How does intensity change with distance? - answer...
