  1. What type of wave make up sound? COMPRESSIONAL WAVES

  2. In sound, humans interpret or perceive INTENSITY as __. • LOUDNESS

  3. Which part of the ear amplifies sound? • MIDDLE EAR

  4. How does temperature effect the speed of sound? • As temperatures increase so does the speed of sound • As temperature decreases so does the speed of sound

  5. Which words go together? • Intensity • Pitch • Energy • Loudness • Frequency • Amplitude Intensity, energy, Loudness, amplitude Pitch & Frequency

  6. If we increase the frequency of a sound, what else will change? • PITCH

  7. What UNIT is used to measure INTENSITY OF SOUND? • DECIBELS

  8. Which part of the ear collects sound waves? • OUTER EAR

  9. Which part of the ear interprets the sound wave? • Inner ear

  10. What two things will affect the speed of sound? • TEMPERATURE • DENSITY

  11. What two things will affect loudness of a sound? • Distance • Energy

  12. What unit is used to measure frequency of a wave? • Hertz (Hz)

  13. When the intensity or loudness increases, what happens to the sound wave? • AMPLITUDE increases

  14. What are the two types of waves? • Mechanical & • Electromagnetic What makes electromagnetic waves different from mechanical? Electromagnetic can travel through EMPTY space, mechanical waves must travel through matter.

  15. What unit is used to measure loudness? • Decibels (Db) • What is the threshold of pain in decibels for the human ear? • 120 Db

  16. Frequency of a wave is measured in __. • Hertz • What is the range of frequencies that human can hear? • 20-20,000 Hz

  17. Humans perceive HIGH frequency as • High pitch, high note • Humans perceive LOW frequency as • Low pitch or a low note

  18. Will sound move faster in high temperatures or low temperatures? • High temperatures (warm)

  19. Sound will move faster in __ • Air or • Water or • Steel ? • Steel

  20. What type of wave is a sound wave? • Compressional wave

  21. What characteristic of sound is demonstrated when you hear echoes? • Reflection • What do we call repeated echoes? • Reverberations

  22. What do blind bats used to steer? • Echolocation • What do submarines use to steer? • RADAR (a type of echolocation)
