1 Sound is __vibrations__ you can hear. 2. To produce sound, an object must __vibrate__. 3. Sound can be transmitted or travel in __waves__. 4. Pitch measures how __high or low__ a sound is. The faster a vibration is, the higher the pitch. 5. An example of a low pitch would be: __barking__ like a dog. An example of a high pitch would be squeaking like a __mouse__. 6. __Volume__ is the loudness of a sound. 7. __Compression__ is the part of a sound wave in which the air is pushed together. (Think of a slinky bunched up.) 8. A __sound wave__ is a moving pattern of high and low pressure that you can hear. 9. Amplitude is the measure of the __strength__ (tallness) of a sound wave. A taller wave stands for a higher sound. 10. __Wavelength__ is the distance from one wave to the next in a sound wave. 11. Sound waves travel __away from__ the vibrating object in all directions. 12. Sound waves travel through __solids, liquids and gases__. 13. The more objects a sound wave must travel through, the more the wave is broken up or __lowered__. 14. The farther you are from the source of a sound, the __softer__ the sound will be. Crest wavelength Amplitude Trough ||
