Question

in movie theaters, they build the walls between theaters with materials that block the sounds from traveling to the next theater. what material would be best? materials that transmit sound waves. materials that absorb sound waves.

Explanation:

To block sound between movie theaters, we need a material that reduces sound transmission. Materials that transmit sound waves would allow sound to pass, while materials that absorb sound waves convert sound energy (e.g., into heat) and prevent it from traveling. So absorbing sound waves is key for blocking.

Answer:

Materials that absorb sound waves.
