"the new AirTag is 50 percent louder than the previous generation, enabling users to hear their AirTag from up to 2x farther than before"

Can that really be true?

If you’re 2x farther away, the intensity of the sound with be 1/4, because of the inverse square law, so logically your speaker would need to be 300% louder.

  • And, technically, if you are 2x farther away, you are 3x as far away, so the intensity would be 1/9.
