#### Slide 14 -Tekstslide

4) Listen to these two sounds. Of which does the sound wave have a higher amplitude?
Sound A
Sound B
• Make sure to be in presentation mode.
• Click the icon to play the sound.
• Make sure to keep the volume of your computer the same!

#### Slide 15 -Tekstslide

4) Listen to these two sounds. Of which does the sound wave have a higher amplitude?
Sound A
Sound B
• Make sure to be in presentation mode.
• Click the icon to play the sound.
• Make sure to keep the volume of your computer the same!
The soundwaves of sound B have a higher amplitude, because the sound is louder.

#### Slide 16 -Tekstslide

5) Which of these two sound waves will produce a louder sound? Explain.

#### Slide 20 -Tekstslide

6) Describe what the amplitude of the wave and what the amplitude of a sounds wave says about that sound.
The height of the peak of a wave measured from the center.
The loudness of a sound.

#### Slide 21 -Tekstslide

6) Describe what the amplitude of the wave and what the amplitude of a sounds wave says about that sound.
