The acoustical insertion loss of linear arrays of equally spaced suspended cylinders was measured. Insertion loss values were obtained for a varied number of cylinders, angle of incidence, and tube spacing for both solid, and expanded metal cylinders. The expanded metal cylinders were found to produce the same visual effects without the large insertion losses that the solid tubes produced.
