  • Set up the sound level meter near a speaker producing a constant sound.

  • Cover the speaker with different materials (bubble wrap, cloth, newspaper).

  • Use the sound level meter to record the sound levels (in decibels) for each material.

  • Repeat for three trials for each material.

  • Record your results after each trial.
