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!

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.

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

The soundwaves of imag 2, because they have a higher amplitude.

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

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.

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.

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 maximum displacement of wave compared to it's rest position.

The loudness of a sound.

Bonus

1. What do you think happens to the loudness of a sound when two soundwaves meet?

Interference
