Feelings are different from person to person. So don't talk of "measuring" the "loudness". You can really measure the sound pressure with a sound pressure level meter. At 8 ft from the speaker sound pressure level (SPL) is 28 decibels. What is loudness 4 ft from the speaker? You get 6 dB more level at half the distance r = 1/2, that is 34 dB. The sound pressure varies with distance 1/r from the sound source. There is nothing squared! Scroll down to related links and look at "Sound pressure p and the inverse distance law 1/r".
