I was in Mount Angel, Oregon, last month and noticed that they had removed more horns from their 3T22. I suppose it is because a senior apartment complex was just finished across the street and the siren is eye level with the third floor windows. I heard this siren four miles away one night (facing the other side of the siren with the horns as in the "before" picture), and the high note was a little louder, but I heard both tones. From the apartments across the street facing this side of the siren, will the removal of more horns really make a noticeable difference? Would it be better, at least aesthetically, to remove them all?
