Document Summary
Your brain hears like a chord and have to determine what notes make it up. Complex vibrations can be described as a group of simple vibrations. Intensity: more valid measure of sounds are softer than amplitude. Hz is calculated by dividing 1/time is seconds. When you add them together you get a complex wave (is not 300hz?) The taller you are, the longer your neck is and the longer the sound waves will take to move from vocal folds to the air. When boys his puberty, their voice lowers because their larynx drops and then it takes longer to transmit longer so lower pitch. Pitch and loudness are psychological and perceptual properties. Corresponds to physical properties of frequency (hz), amplitude and intensity (db) Wave a=sum of wave b + wave c ***know for exam. From zero to first wave (. 3) plus the distance from zero to second wave (1) = where we draw a point (1. 3)
