|
amplitude (intensity) |
magnitude of displacement of a sound pressure wave. (perceived as loudness |
|
|
frequency |
the number of times per second that a pattern of pressure change repeats |
|
|
Hertz |
unit of measure for frequency = 1 cycle per second |
|
|
loudness |
psychological aspect of sound; perceived intensity (more intense= louder sound) |
|
|
pitch |
related to perceived frequency (low= low pitch TUBA) (high= high pitch PICCOLO)
|
|
|
decibels(dB) |
unit of measure for physical intensity of sound |
|
|
sine wave |
also called pure tone, simple sound (variation as function of time is this) |
|
|
spectrum |
complex sounds are best describe in this. representation of the relative energy (intensity) present at each frequency |
|
|
harmonic spectra |
caused by simple vibrating source; energy is at integer multiples of fundamental frequency
|
|
|
fundamental frequency |
lowest frequency component of complex periodic sound |
|
|
timbre |
sensation by which a listener can judge that 2 sounds with same loudness and pitch are not similar |
|
|
ossicle |
any 3 of the tiny bones of the middle ear |
|
|
malleus |
receives vibration from eardrum and attached to incus |
|
|
incus |
middle of 3 ossicles, connects malleus and stapes |
|
|
stapes |
presses against oval window of the cochlea on the other end |
|
|
oval window |
flexible opening to the cochlea; stapes transmits vibration to the fluid inside |
|
|
tip link |
tiny filament that stretches from the tip of a stereocilium to to the side of its neighbor |
