MARCH-APRIL 1952 ill BUSINESS Lift The Ceiling on .Learning CWith a New School libraries/ for the lower grades, develop concentration and study habits that are of benefit throughout a person's life. In Roosevelt Elementary, Mo* line. III. ACOUSTONE minerol sound quieting tile on the ceiling encourages this condition of study quiet. "ALLEGELATIONS TO THE AMERICAN FLAG rf*~| in which it stands" Little Mary came home from school and repeated her newly learned pledge to the flag. It was the funniest thing her family had heard in a long time. They added it to their "bright-sayings-of-Mary" collection, and everyone laughed. Yet in reality it was tragic. Little Mary, in her formative years, learned by sound. She repeated what she had heard in a classroom that was so poor acoustically that uttered sound was distorted before it reached the pupils. Poor acoustics put a ceiling on Mary's ability to learn. In-school learning at all age levels is largely learning by hearing. Only correspondence schools teach by sight alone. You can lift the ceiling on learning imposed by poor acoustics, with a new ceiling of incombustable, sound controlling ACOUSTONE mineral tile. Such treatment is equally available to existing structures, and to buildings being planned or built. ACOUSTONE minartl til* application* it Univenitv of Arkansas by Harry G. Barr Co.. Fort Smith.

Inc photograph '.SCHOOL ACOUSTICS check list Acoustical contractors are careful salesmen. They are sincere in their desire to avoid over-selling. They often tell a customer that his needs will be equally well served by less acoustical tile than he is willing to buy. They recommend ACOUSTONE mineral tile or AUDITONE fiber tile only when an area benefits from its acous tical properties as well as its appearance. The following check list is presented in the same spirit. In existing buildings, improvement with acoustical tile is often a progressive thing. It starts in one area, and because the improve ment is so noticeable and desirable, future orders are received to spread its use over an entire structure. The check list which fol lows is a guide to areas in schools where sound control materials are most profitably installed. For a progressive job they are in a general order of preference and importance. Follow this list in the order indicated and the acoustical benefits will be cumulative. AUDITORIUM A logical starting point, because an auditorium is worthless if its acoustics are poor. CAFETERIA AND KITCHEN Meals digest better, and a lunch hour is more refreshing if surroundings are quiet. Home isi a HAVEN Girl's Preparatory School, No. Chattanooga, Tenn., brings quiet to its corridors and cafeteria with AUDITONE fiber tile. AUDITONE has a dis tinctive slotted pattern, and is acoustically the equal of other tiles which sell at greater cost. The Curtin Co., Chattanoota, acoustical applicators. I CORRIDORS School corridors carry heavy traffic at certain peri ods, and because they are often tunnels of hard surfaces, the noise factor is high and disturbing. When properly treated acous tically the feeling of quiet present is a deterrent to thoughtless boisterousness. I CLASSROOMS Students don't learn what they cannot hear or understand, and poor acoustics can defeat the entire purpose of classroom study. Classrooms and practice rooms, and industrial arts shops are "musts" in school economics. g LIBRARY Student libraries often have a noise problem created by irrepressible occupants--a noise problem which can be minimized by use of acoustical tile on ceiling surfaces. I GYMNASIUM An echo chamber supreme, in which loud voices and noise is the rule rather than the exception. Acoustical treat ment can reduce noise to low levels which present no interference with instruction or study in other rooms. g SWIMMING POOL Tile, water, glass: all are highly reflective of sound, and all are present in a swimming pool room, where there is much verbal exchange. Acoustical tile lowers the noise level so the instructor may be fully understood by his class. PERFATONE metal pan tile or perforated asbestos board is especially suited to the high moisture conditions which swimming pool areas provide. 4 Home of Dr. <i Mr*, toy Baiyeat. John B.

BB024 1660 Kitchens are usually devoid of "soft" adornment, and contemporary planning often leaves the kitchen open to dining or other areas of the house. This makes a sound quieting ceiling highly desirable. In the Walter Ramsey kitchen, Portland, Ore., AUDITONE fiber tile does an attractive job of providing kitchen quiet. Darrel Herbert, architect Emerl t Zadnik Co., Portland, acoustical applicators MOTIF'D ACOUSTONE adds extra appearance value to this living room in the Oklahoma City residence of Mr. and Mrs. John F. Eberele. Sorer, HiU & Sorer, architects. Denman Floors Co., acoustical applicators or ouses are usually full of soft things--carpeting, draperies, H upholstered furniture. In many cases these items take care of the sound '.'Sk*1 comroi problem. However there are rooms at home which can be improved immeasurably by a sound absorbent ceiling. Some are pictured here. err- Far left: Recreation rooms often boast large glass areas and floors covered with hard tile-like material or handsome wood which is left uncarpeted. This mokes a noise problem, especially considering the na ture of use made of these rooms. Acoustical tile pro vides fine appearance and effectively reduces noise. Three examples ore shown here, using ACOUSTONE mineral tile on the ceiling. Left: Home of Mr. and Mrs. S. J. Hammerman, Glencoe, III. The acoustical ceiling is an es pecially good complement for obtaining best results from the built-in high-fidelity radio and television equipment. (Turn page for more on this subject.) In this recreation room of Mr. and Mrs. Theodore Thorn ton, Hinsdale, III., fine music can be enjoyed at its finest, because of the acoustical ceiling treatment and the equip ment provided. High fidelity radio and record playing equipment has been gaining increasing popularity, and con be acquired at relatively moderate cost by buying ond hooking together o tuner, amplifier, record changer and speaker. These components can be acquired from local radio parts stores in larger cities or by mail through any one of several radio equipment companies. When properly housed, tone production is superior to most commercial sets. The two cabinets shown here (one is the speaker) are adopted from sliding door cabinets introduced by our sister publication POPULAR HOME magazine. These cabinets are shipped completely cut, drilled and sanded from beautiful hardwood plywood. Information about radio component combinations and the cabinets is available from SOUND BUSINESS, 300 W. Adams, Chicago. The SOUND BUSINESS high-fidelity radio rt Hall AT HOME Radio television and recordetii'sound, have brought the concert hall into the home. To some people this means nothing. Other millions of people find their greatest pleasure in music either as a "spectator" or as a participant. This page is for these latter millions. It suggests how a room in almost any home, large or small, can be made to serve the interest of a music loving family. Two solutions are shown here. One converts an extra bedroom, either upstairs or down, into a so-called music room, and yet allows it to retain its usefulness as a guest sleeping room. The other shows how a living room can serve its owners' musical taste as well as serve the many uses to which living rooms are traditionally devoted. Study them carefully in all of their detail. See how acoustics can be controlled in these rooms with sound quieting tile to make them serve all functions better. And note especially how economically the finest in music can be achieved in the home. This is no sport restricted to kings. Fine music is no more costly a hobby than photography or woodworking or many other pursuits of leisure hours. If the living room is to be the center of music interest, this may be the answer to its arrangement. Speaker for the high fidelity radio and television screen (if desired) are part of an angled wall which directs their entertainment to the principal seating area. Controls for radio-phonograph are located at the seating area, as is a motion picture projector found in an end table, mounted on a swing-up board like a typewriter. The screen drops from behind a baffle board. For good listening the ceiling is ACOUSTONE mineral tile. The spare bedroom can become a haven for the music minded, and still serve as a guest sleep ing room. Here is one that has been so converted. Equipment is optional, but we show an electronic organ, and a wall of cabinets which includes the control and speaker units of the SOUND BUSINESS high fidelity radio unit described elsewhere. Sound is controlled by area covered by sound absorptive material. In a small room such as this, covering the first two or three rows around the perimeter of the ceiling of the room gives almost as much sound absorption as covering the entire ceiling area. Here these strips are done in AUDITONE fiber acoustical tile. The center area, a sound reflective surface, helps distribute speaker tone. BB024 1662 Corridor Confusion with Acoustical Tile ENRY RUSSELL'S SENTIMENTAL Halls of Ivy immortalizes in song the H "echo through the years" associated with the corridors of alma mater. Alma mater's halls are fast losing their echo, however, with the steady advance of acoustical tile in schools and the corridors of all types of public buildings. It is well that this is so. Corridors lack soft, sound absorbent decorative materials. Floors are hard surfaced material designed for heavy duty wear. Walls have smooth hard surfaces to facilitate cleaning. This is the perfect condition for sound reflection--reverberation--unless there is present an acoustically absorbent material on the ceiling, and if possible, on the upper walls. The noise of milling crowds and many voices, which is present at high traffic periods in any corridor area, can be extremely disturbing when increased by reverberation. Even footfalls of a single person are multiplied to disturbing noise levels in an untreated corridor. Corridors and lobbies are good starting points for acoustical treatment in an existing building whether it is school, office structure, theater, apart ment or hospital.
