M Rooms SHOULDN'T BOOm Amplification is not the sole solu tion to the problem of audibility in rooms of great size. Amplifiers will boost the sound level so that it will reach all parts of such a room, but usually tremendous reverberation is also present. A room such as the coliseum of the University of Kentucky at Lexington, shown here, in untreated condition, would have a reverberation time as high as 15 to 20 seconds. It is easy to realize that speech from the finest amplification system could hardly be understood when each word lingers 15 seconds to confuse the intelligibility of succeeding words. The aim of the acoustical engineer is to reduce this to a two second rever beration time. To accomplish this in the Kentucky coliseum, this remarkable clear span ceiling of 225 x 336 feet was created by suspending acoustical tile with a Z-spline system, 49 feet above the playing floor (see diagram). The presence of an audience makes a big difference in the acoustics of such a room. Clothing absorbs sound waves and reduces reverberation. The acoustics of this sound treated room are such that even with the room empty,asshown here, the instructions of the coach speaking to the famed Kentucky Wild cat basketball ream in normal conversa tional tones, could be understood clearly without amplification on the top row. Curved surfaces often create acoustical problems in large rooms. In St. Paul's Episcopal Church, Louis ville, Ky., the vaulted ceiling made hearing very difficult in certain portions of the room. Acoustone mineral tile adhered to these curved ceiling sur faces made an acoustical improvement that is the marvel of the entire congregation. Its beauty is a fitting complement to the new decorative treat ment that was also a part of the renovation job. Pochei Ctowinf Co., Inc., acoustical applicators. The Southern Baptist Theological Seminary ot Louisville, Ky. has a large chapel that is similar in design to many protestant churches in the South. The appointments of this building are magnificent. Notice especially the acoustical treatment. The front ceiling panels are not treated, permitting o reflection of a spoken message or music to the rear of the room. However the rear panels of the ceiling, and the woll surfaces facing the pulpit ore treated with Acoustone mineral tile to reduce reverberation (below). These include back walls of the boicony, the front surface of the balcony roiling and the bock partition below the balcony. Joseph H.

The proof is no better illustrated than it is in the restaurant industry. Cus tomer preference for a particular restau rant is based not only on good food and service, but also on surroundings. Acoustical tile is not a luxury item. Good, modest-sized restaurants find that an investment in sound control is as im portant to them as it is to the larger, more elaborate dining places. It mini mizes the noise of service. It quiets the mingled voices of many customers at rush hour, and helps to make dining in these establishments a pleasant, relaxing experience. The appearance of econom ical Auditone fiber ceiling tile is neat and effective as well. Colorful native posters and glass table tops covering a dis play of postcards and photographs of Mexican theme, set the scene for Chile Bowl Restaurant of Louisville, Ky. Good food,'1 o spark of Mexican culture, and comfortable quiet provided by a ceiling of sound quieting Auditone fiber acoustical tile, attract a high volume of business to this fine small restaurant. 33016 0252 ACOUSTON mineral tile installation by Oenman Floors Co., Oklahoma City, Okie. BB016 0253 The Supreme Court Chambers f the State of Oklahoma, handsome and impressive though they were, had ne shortcoming. This room, where the ability to hear and comprehend is so important, was acoustically imperfect. A richly baroque ceiling eliminated ^at area as a possible surface for acous- tical tile. So wall panels at the back and sides of the room were selected for ap plication of sound quieting and con trolling material. Notice that the surfaces at the front of the room were left clear, while others were tiled. Now speech is more distinct and more readily under stood, that justice might be done. --WI W SFf COMPANY M HNoormn, t4 on flock Cevcr / 1 1 1 I !' ii ^ J 1i rr J r. I *a i a r; a I : 4 Combine the wages of o group of executives in conference, and it can be quickly seen that a one hour meeting is a costly item. Maximum accom plishment must be the keynote. This Reynolds Metals conference room is treated with Motif'o Acoustone so that all participants may hear the speoker clearly in an atmosphere that is condu cive to concentration on the subject at hand. . Does Office Beauty Pay? Reynolds Metals says "Yes" Good Planning and good appear ance pays off in office construction. Attractive offices attract the cream of secretarial and clerical employees and contribute to their interest and happi ness in their jobs. Good looking offices make a favorable impression on all vis itors -- they add prestige to their own company personnel and put them on a better bargaining level with those with whom the company does business. Acoustical properties are part of such a picture. Sound control materials con tribute not only beauty, but also an atmosphere that complements visual beauty. They boost morale and effi ciency, reduce working fatigue. i To house their sales headquarters, fasn growing Reynolds Metals Co. converted; what had been a war production piano in Louisville, Ky. into attractive office quarters which exemplify rhe truth??- stated above. Good planning and a regard for thetic values are apparent throughod the structure. Aluminum building terials were used extensively and effe< tively. Visitors' parking is within building and with direct entrance the reception lobby. Sales conferen rooms are numerous and accessible every floor where they are needed. Di l6 0254 , 1'+,. ew Visual Uses for slotted acoustical tile The distinctive slotted pattern of Auditone fiber acoustical tile has direction. This factor can be used to influence the flow of traffic through a room in a manner that is as subconscious and subtle as the acoustical properties that the same material provides to such area. The sales psychology of a moderate sized store is to move customer traffic through the entire length of the space, even though it has entered for a single purchase. Moving through the store exposes the customer to all the displays, and may create desire for an additional purchase. The traditional basket weave pattern of Auditone fiber tile application provides a pleasing, even texture to a ceiling. In such a field why not build a "highway" on the ceiling, in which the Auditone slots all point the direction that it is desired for traffic to move; four tile wide, starting at the store entrance and leading past the principal display areas to the back of the space. This principle can apply to restaurants, residences, theaters, any place that traffic has definite flow. Auditone pattern has other psychological uses. A narrow room can seemingly be widened in appearance by running the tile pattern in a single direction across the width of the room. In the handsome Tremaine residence appearing in the last issue of this publication, direction was emphasized by tile pattern placement. The Owen's Cafe installation on page 4 of this issue shows a slight and interesting variation of pattern. Use Auditone fiber tile for its acoustical properties, but put its appearance to work too. The acoustical application company in your trading area which is named on the back cover of this magazine can be of aid in this respect.
