Definition: In physics, "attenuated" refers to a phenomenon where one quantity decreases in magnitude or intensity as another increases. It's like when you lower your phone from a high place and it starts getting louder. For example: - If you raise your voice by 30 dB, the volume of the sound goes up by 30 times. - If you lower your voice by 25 dB, the volume of the sound goes down by 25 times.
