The Tower window air conditioners are next to a concrete corner wall. The noise bounces off the concrete and deflects into adjoining units. This is a loud humming, droning noise -- not white noise. The noise penetrates closed windows. Park La Brea tower air conditioners run at ~80 dB, adding ~20 db noise to adjoining units: FOUR TIMES LOUDER THAN NORMAL!
