Which term describes sound energy received per second per unit area?
Intensity
Sound energy received per second per unit area is called Intensity, a measure of how much sound power reaches a given surface.
Frequency measures the pitch of a wave, Echo is a reflected sound, and Pitch describes perceived highness/lowness of sound — none define energy per unit area per second.
Hence, Intensity is the correct answer.
