Sound
Wave
Form of energy that travels through matter as waves
Disturbance that transfers energy from point to point

FrequencyThe number of waves produced in a unit of time
PitchThe highness or lowness of a sound
AmplitudeMeasure of the amount of energy in a sound wave

How do we hear sound?
![Page 13: Curriculum Science Unit Sol 5.2 Powerpoint](https://reader036.vdocument.in/reader036/viewer/2022062405/5560c7e6d8b42a0d088b47c0/html5/thumbnails/13.jpg)
Why do humans & animalshear & make noise differently?
•Animal brains are not as complex as those of humans
•Some species do not have vocal cords.
•The vocal tracts of animals may differ in shape and size, so vocalizations sound different
