its absorbing power was nearly doubled, we used only 3,315 square feet of felt instead of 6,300 square feet. We paid the Johns-Manville Company $1,135.28 for materials and labor. To this should be added $1,400 for the cost of scaffolding and wooden ribs constructed for mounting the felt, a total of $2,535.28, or a saving of at least $2,186.72. The likelihood is that we should have paid $1 per square foot for the felt, thus making the saving somewhere between $3,000 and $4,000, instead of the conservative estimate as shown. Other changes were made in the Auditorium. A pipe organ was installed, the lighting system was changed, and the interior was redecorated. All of these modifications affected the acoustics and were considered when calculating the amount of hairfelt to be used. The results obtained have been generally satisfactory. The remodeled Auditorium has been used almost continuously under varied conditions for music and speaking and has been found to have acceptable acoustics. A speaker with a moderate voice can be heard and understood by auditors in the most distant seats. According to experts, the music of the pipe organ is satisfactorily rendered. The room is suited also for orchestra music although for this case the carpet is removed from the stage so as to provide a sounding board for the instruments. The reverberation is not excessive even when no audience is present so that rehearsals may be conducted under favorable conditions. Several instances of echoes have been reported but these do not appear to prevent the words of the speaker being understood. While the best evidence for the improved conditions was furnished by the favorable opinion of auditors, it was deemed desirable to get additional information by experiment. Accordingly, the time of reverberation was determined experimentally by Sabine's method and proved to have the acceptable value of 1.81 seconds with an average audience of 1,200 people. Calculations showed that the absorbing power of the hairfelt was increased by mounting it out from the walls. Echoes were tested by the arc light reflector. The padded walls diminished the sound to such an extent that they produced little trouble, but several unpadded walls of comparatively small area produced echoes under particular conditions. For instance, when the speaker faces such a wall so that the auditor can see the profile of his face, an echo is perceptible. This is because the sound passing directly to the auditor is diminished while that reflected from the wall is augmented. Aside from these weak.echoes the acoustics appear to be satisfactory. It may be well to consider the future possibility of padding the pendentives in the dome. I call attention again to the desirability of placing a cork carpet, or similar material, in the front lobby and on the stairs leading to the balcony. Respectfully submitted, F. R. WATSON, Assistant Professor of Physics.
