diffraction | sound waves dont travel in a strate line. the sound spreads out |
interfrence | sound waves meet and interact with eachother |
loudness | depends on two factors-1-the amount of energy
2-the pitch |

infrasound-below what a human can hear | below what a human can hear |
the doppler effect | the change in frequency of a wave of a wave as its source moves in the relation to an observer |

auditory
prossesor | contained hair cells which makes you hear
sents message to brain

hear loss | if you hear something to lowd this occurs |
sonar | is the use of reflected soundwaves to detected of locate onjects underwater |
echolocation | is the use of reflected stored waves to deter main distances or to locate objects |
sonogram | the device uses the reflected ultrasound waves to create a picture |
