If you have your left ear pressed to the surface of a wooden table and a partner taps the table with a ruler, why would the sound in your left ear be different from the sound in your right ear?  

 

   

   

•    Sound waves travel to the right ear through a gas, but sound waves do not reach the left ear.

• The right ear receives sound waves that traveled through a gas, but the left ear receives vibrations instead
  of sounds.

• The right ear receives sound waves that traveled through a gas, but the left ear receives sound waves that traveled through a solid

• Sound waves travel more slowly through a solid, so the tapping sound will reach the left ear after the same sound has reached the right ear.
